Episode 14: Myths Revisited

Air Date: June 8, 2004

REVISITED: Soldiers marching in unison can cause harmonic oscillation in a bridge and cause it to collapse. (From Episode 12)


The first time the myth was tested, the miniature bridge was flawed enough in its design to get an inconclusive answer, but with this test, just testing the natural resonant frequency of a simple wooden bridge, resulted in a plausible conclusion, but it is very improbable.

(This myth was retested for this episode but it ultimately did not air.)

REVISITED: A frozen chicken will penetrate aircraft or train windshields better than a thawed chicken. (From Episode 9)


When re-visited, frozen chickens could penetrate sets of layered glass panes better. Listed as Plausible because it’s uncertain the original myth actually occurred.

REVISITED: An ice bullet can kill someone without leaving a trace. (From Episode 1)


They retested using slow-frozen bullets that were stronger than the ones they used previously. The bullets simply vaporized when the trigger was pulled.

REVISITED: Using one’s cell phone while pumping gas/petrol can cause an explosion. (From Episode 2)


The battery of retests the MythBusters performed reaffirmed their original Busted verdict.

SPINOFF: Leaving a can of aerosol spray or cola inside a hot car can cause it to explode. (From Pilot 2)


The aerosol cans didn’t explode inside a car after sitting in the sun for hours. Both aerosol and cola took temperatures of over 300 °F (150 °C) to blow.

SPINOFF: An inflatable brassiere can explode inside an airplane as it climbs in altitude. (From Episode 2)


The different types of inflatable brassieres tested proved capable of maintaining their integrity even at altitudes fatal to humans.

SPINOFF: Urinating on an electric fence can cause electrocution. (From Episode 3)


Upon retesting the myth on an electric fence it was found to be confirmed, but the rail was still Busted. Distance was the factor, as the urine stream breaks up less at the close range needed for urinating on the fence than urinating on the third rail, thus ensuring a direct line of current between ones body and the electrical source.

REVISITED: Covering one’s body in gold paint can kill a person by skin asphyxiation like in the James Bond movie Goldfinger. (From Pilot 3)


When Adam retested the myth, he reported some discomfort, describing it as a slight flu-like feeling, but he nonetheless survived.


  1. Mojax says:

    Cans of cola CAN explode in a car. I had a whole twelve pack explode and then dry out from the summer heat before I found out. AND the day before yesterday after some friends and I went out to play some basketball, one can of Coke Zero exploded as we were driving away in the back of his jeep cherokee, we thought we were shot at. Every can that explodes goes through the top of the can.

  2. John says:

    I had a 6 pack of pepsi and a 6 pack of Dr.Pepper that would not fit into my cooler for our camping trip. All but 3 cans had exploded by the next time I hopped in my car 2 days later. They might be neglecting the fact that the dark color on the can might channel the heat directly into the cola making it much hotter than the actual temperature of the car

  3. James says:

    I had a case of coke explode in my silver ’93 Probe in like 94 or 95.
    They were in the floor boards behind the passenger’s seat

    I do not leave sealed containers under pressure in the car anymore

  4. dc says:

    I’ve never seen cans of cola explode from heat before. Cold, sure. I’ve had that happen, where it was cold enough to start freezing.

  5. Priscilla says:

    i have a dodge ram 1500 and i had a can of dr. pepper in there that had explode sitting in my newborns car seat bass i think it depends on how big of an area the sun has to heat up to get the can to explode

  6. Jim says:

    I manage an autoglass shop and a customer called me in a panic . I went to the hotel where she was staying. An air freshner can had the bottom blown out , went across the dash board hit the steering wheel and almost all the way out through the windshield. I kept the can for years in my collection of odditys. I have never seen any thing like it since. It was a black car with a black interior and the can was on the dash board. It also took a small chunk out of the steering wheel. It takes alot of force to penetrate a windshield, especially with something the size of a can.

  7. Kat says:

    Unfortunately I missed the episode, but did you factor in the movement of the vehicles? This could contribute to pressure build up and when combined with the heat factor, the end result could be an exploding can. (Most of the previous comments mention items left in vehicles for a couple of days or while in motion until they exloded.)

  8. Suzanne says:

    I too have had soda cans “explode” in my car. I bought a 12-pack of soda and left it in my car trunk. The next day as I was driving when I heard popping sounds it occurred to me to check the trunk I found the 12-pack of soda was leaking. While the cans did not literally explode of the 12 cans of soda the top 8 cans were deformed by the reaction of the contents heating. They looked like someone had taken a stick and poked upwards from inside. On one can this deformation occurred right under the pop-top causing the can to open and spill its contents.

  9. Cara says:

    Yesterday – 8/27/07 – I went into work at 12:00 eastern time and when I got back to my car at 5:15 eastern time the two cans of pepsi that I had JUST Put in the cair had exploded, the soda was all over my windows, my seats and everything. I am not sure if it is just that I live in Florida and have a black car or what, but it was quite gross to open my car to. The cans also were seriously deformed, the top of them had popped up like they were a volcano… so this myth obviously is not tested right by the Mythbusters…. becuse cans DO EXPLODE in the heat.

  10. Rod C says:

    Re the Ice Bullet. Could this actually work if a non explosive weapon were to be used; for example a gas-powered or spring-powered gun. I have a vague recollection of spring-guns being used in the past and being outlawed for military use in the 19th Centrurty

    • michael says:

      what about compressed air? an ice bullet that is thrown forward by compressed air will not melt unless it is 500 degrees outside, plus, the bullet will shatter on impact with a bone, then the shards will melt due to residual body heat, rendering the kill, untraceable

  11. Robin says:

    There were a bunch of coke cans in the back of my dad’s car. All 12 exloded. The sides were blown out and everything. Loook like some osycho took a stick and started jabbing the heck out of the cans. I’m not surprised though… the weather in Kentucky is crazy and anything can happen.

  12. R.J. says:

    I agree with Kat. Shaking a can of pop does increase the pressure inside, which, when combined with the increased pressure from heat, could cause the can to explode. That might be the most likely explanation for the “when I was driving…” anecdotes.

  13. Chris J. says:

    I had a can of electrical contact cleaner explode in my 1987 Ford Ranger. Part of the can hit a piece of metal trim in front of the passenger area with enough force to dent it and knock it loose! The contact cleaner was not flammable.
    Vehicle parked in the sun.
    Hot summer day in Maryland, Harford Co.
    Windows up / doors locked.
    No witnesses.

  14. Charlie says:

    I have had several coke cans explode after being left in my car for only a couple of hours (i.e. getting to work at 7:30 and forgetting the can until 12:00pm at lunch). This has happened several times while my car has been parked in the parking lot of my office. I live in central Alabama and the can was in the cup holder each time. Therefore, it was unlikely to have suffered much agitation from the drive. Also, while I was working at an airfield in central Alabama, in the summer, I would often leave leftover pizza, wrapped in aluminum foil sitting on the dashboard and many times it was as hot as it would be has I placed it in the microwave for 40-50 seconds. The windows would be rolled up completely each time and the car was parked in direct sunlight with an average outside temperature in the mid to upper 90’s.

  15. Grant says:

    I would like to see the ice bullet myth retested with an air gun of some sort that would not create a hot explosion in a chamber, thus vaporizing the ice bullet.

  16. Steph says:

    While serving time in Iraq, I had a can of soda explode in our vehicle. So, technically yes, soda can explode in your car.

  17. Lance Brydges says:

    I wonder if a fire retardent wadding would be sufficient enough to protect the ice. All that should affect it then is barrel friction. A smooth bore shotgun with several types of wadding might prove better.
    Keep Busting!

  18. Paul Waters says:

    Seems like i am not the only one who has had a soda can explode in their car. In my case the soda was there for at least 3 days. It was a cheap soda and my windows were up. I imagine it was 100 degrees fahrenheit outside or 38 C. How is it the Mythbusters got this one wrong?

  19. peter smith says:

    Actually, for all you Dan Brown skeptics, ice bullets do exist – and have done for at least 20 odd years. They are coated with glycerine to protect the projectile from heat during flight to target. Largest calibre I’ve heard of is 7.62mm. Max range is about 150 metres.

    As to the storyline of ‘Deception Point’ (c), Delta using ice buckshot (I think), it is not too far fetched. After all, if we can have bullets made from ice, why not other munitions of a larger calibre?

    The Priory of Scion and Corpus Dei – both exist, as does the Illuminati. I respectfully suggest you research St John Ambulance [surprise!], the Knights of the Templars, Maltese Knights, Knights of the Round Table [King Arthur], Spanish Inquisition etc, etc.

    Everything can be traced back to the Holy Grail – be it a brother and sister or the cup which Christ allegedly drank from at the Last Supper or even Mary Magdelane as Dan Brown suggested.

    • Jeanette says:

      can the ice bullets be shot from any air gun??? most likely a small gun so as not to be noticable??? guy sits on porch shooting at my house

  20. todd says:

    A soda exploded in my vehicle yesterday — It was 104 degrees outside.

  21. dnksmom says:

    Cans CAN, and WILL explode – and not jus t soda cans. We had a WD-40 can go through the windshild the other day. If you’ve never seen a pop can explode all over your trunk or car….you obviously have never parked your car in the southern midwest during the middle of the summer!

  22. Ryan G says:

    I just had a can of coke AND a can of sprite explode in my car. They were on the backseat of my firebird and it got up to 93 degrees outside, the sun was shining in and the windows were all the way up. Somehow or another, I’m now cleaning up soda on the floor, front windshield, rear window and all the seats. Soda cans CAN explode. I have the proof for anyone who wants it.

  23. ker says:

    Yes, soda cans CAN explode in the car. I rarely drink soda, but I bought several 12 packs for my fiance who drinks it as if it were the only liquid on earth. I didn’t think heat would make them blow up (cold, yes); so I left them in the car for a two days since I didn’t want to lug them up to my third floor apartment. I went to get them today — HALF of the cans had the tops popped up, but not exploded. At least one exploded because it busted the box and messed up the inside of my car. When I brought the rest in the house, one exploded as I set it (set, not slammed) it on the counter. I blasted out of the box and splattered all over my kitchen. Needless to say, my fiance owes me big time.

  24. war gammer says:

    have had cans of soda explode in my car and a can of r-134a was working on ac an left the can in the hatch of a 280z directly in the sunlight an busted out the glass was also really hot out around 110

  25. Eric says:

    I did not see this episode, But a co-worker took me once that he had a can of CRC (like the WD40 story above) explode in his car one day (in Auckland, New Zealand).
    (I can not remember the damage, if any – I just remember not to leave any CRC can’s in direct sun light in the car)

  26. Michelle says:

    They need to revisit the can theory, I had a six pack in a cooler in my truck and thought it would be fine, came back a few day’s later and had a major mess, dried coke all over the windows, headliner, etc….everything was coated in nice sticky, dried coke. You couldn’t even see out the window. I hate to tell them this one is fact.

  27. Dana says:

    The exploding soda can was revisted. This is a FACT that they can explode. When they did the experiement they did it in a stationary heated container. What if it was in a moving vehicle where the carbonation is getting more activated? Just like shaking a can and opening it. We had several cans explode in the trunk on a road trip cross-country, this was also in 1978. The soda manufactures have made improvements to their cans, so this could also be a fact finder.

  28. DRP says:

    I am a safety inspector for a major refinery and folks, cans DO indeed explode inside hot vehicles. The idea that it has to be moving is of no consequence, it may be somewhat contributory in some cases for obvious reasons but the fact that pressure builds up is apparent. I don’t have extended years experiance as a stunt guy but I do have over 20 years experiance as a safety manager and have seen more than a few cans of paint, cola, WD-40 and most any aerosol type can explode. Most with extreme effects on the inside of the vehicle. I even have pictures!

  29. BCS says:

    I had a can of “Fix-a-Flat” in the back of my car explode today. The can was stored below the trunk area of my Subaru Forester, near the spare tire. LOTS of damage under there…and a sticky mess that took 4 hours to clean out of the trunk. Vehicle had been parked in the hot sun for 8 hours, and I had driven it 2 minutes when it went off. VERY loud.

    I think Mythbusters couldn’t get this to work because they were using an older car. You need a car less than 3 days old for this to work. :) Yes, I bought the car this happened to 3 days ago… Luckily it exploded in an area of the vehicle that acted as a sort of “bomb shelter”.

  30. CB says:

    RE: exploding soda: I don’t know about that but I had a bottle of semi-sparkling muscat (which is carbonated) explode in the car.

  31. AD says:

    There is no doubt that soda cans can explode in a hot car. It’d be great for Mythbusters to determine the temperature at which this happens. I had about a dozen soda cans explode while driving through Death Valley in July in a van. The air conditioning was on full but it was ungodly hot — the air conditioning can only do so much — and I’ve always wondered how hot it actually was in that van.

  32. Nat says:

    I had a can of Fix-A-Flat in the back of my car, and it exploded yesterday and literally blew apart a paperback book that it was near. The weird part is, yesterday wasn’t the hottest day we’ve had this summer.
    So, yea, it is possible, I’ve got a sticky mess all over my car to prove it.

  33. Fela says:

    I live in Hawaii, and the temperature never gets much above 90 here and is usually in the 80s.

    Last month, after I got home at around 1pm, I heard a sound like a heavy book falling on the floor. I walked around the kitchen where the noise had come from and heard dripping.

    A can of caffeine free diet Pepsi (which was in a 12-can fridgepack in my pantry along with a dozen other such boxes) had popped open (the mouth of the can was pushed out) and sprayed out with enough force to wet the door of the pantry and the entire shelf it was on, as well as the puddle on the actual floor. Not cool.

    Last Thursday it happened again. Same type of soda. Same shelf, even. This time I knew exactly what to look for and so minimized the mess.

    My wife and I (she once had it happen, about three months ago, but didn’t find out until hours later and had a big mess to clean up and the shelves were permanently stained with the box artwork) think that this is probably due to heating and cooling of the cans, because it always happens right around the time our home is at around 80 degrees, and right about the time we’ve cranked the AC.

    I can’t remember whether I’d opened the pantry or not those days, but I am positive that the cans were undisturbed for at least twelve hours prior to their explosion.

    I could probably reproduce this on purpose if I set my mind to it, but not dependably, and I really don’t have that kind of time (or willingness to clean.)

    Thank goodness it was diet, or we’d get bugs everywhere.

    Diet Pepsi is more carbonated than most sodas, I believe, and maybe the caffeine free stuff is even worse or something (or maybe it’s just at an ideal height for this.)

    In any case, MythBusters is so obviously wrong that I’m actually a bit ashamed of them. They’re hurting for material lately, so they should probably revisit this and reclaim their honor, in part.

  34. Jane says:

    Has someone ever experienced a gas hair curler device exploding while packed away in a glove compartment, under a seat or boot?

  35. Darryl says:

    The trick is of exploding soda can is prolong heating. So take the temperature up to 125-135 degrees and hold it there for up to 4 hours. Just like my wife does about once every couple of years by not taking the cans out of the car after shopping. She improves her results by parking in the sun and especially if the cans are in direct sunlight.

  36. Bob Poland says:

    MythBusters are wrong!!!!

    I left a 12 pack of diet pepsi and a 12 pack of diet cherry pepsi cans in my car over the weekend. I guess it got really hot in there. Some of the diet pepsi cans did explode and many others greatly expanded. The strange thing is that all of the diet cherry pepsi cans are in perfect shape!

  37. Jen says:

    Soda Can Exploding in Car: Confirmed. Salem Oregon, 96 degree high for the day. Car was left in sun with windows up, can of rootbeer completely lost it’s top and soda splattered on the roof and filled the cupholders. The car had been in the sun for 7 hours when the can was found.

  38. kody says:

    my brother was at work and he had a coke can in his truck and after he got off of work the coke was all over is truck

  39. nikki says:

    our friends had 3 12 packs in their car this weekend–got up to 104 outside–all 36 cans exploded inside the car. It was all over the inside–huge mess!! I saw the cans–all the tops came off.

  40. Mike says:

    Yeah I just got back from a trip here in Florida. Twelve pack of cans sitting in the back seat all hot for a few days. Carried the pack into the hotel, it was dripping all over me. The top of one can was bulged outward completely in a convex shape, and another was halfway bulged out. One can had leaked through the drinking hole, the others I threw into the cooler and drank a few hours later with no problem or loss of quality.

  41. Mick says:

    The frozen chicken penetrating an aircraft windscreen is a bit of a stupid test in reality.
    For one, frozen chickens don’t fly,especially at aircraft altitudes, so it would not be possible to run into one.
    Myth Busted.

  42. Carrie says:

    I had a can of Dr. Pepper I left on the set of my car for a couple of days, because it had gotten warm before I drank it. The weather had been hot here in UPstate NY (spit and hit Canada North), and I had not driven all weekend. I guess, I FORGOT TO PUT IT BACK IN THE FRIG! I found a sticky mess all over the windshield, dash and passenger seat from the can. The top blew 3/4 off and was domed. I still have it if you want to take a look.

  43. Bud says:

    I live in Marion, IA. I went out to my car on August 11th at around 5:00 it was a high of only 87 degrees and there was a huge explosion of Sam’s Cola everywhere. There were 3 cans, one was empty already. The second was completely bubbled out. The third can and main culprit had the top fully blown off, the can itself had a perfect circle where the top blew off, bottom of the can was bubbled out aswell. I threw them away unfortunatly, but i DO have pictures, and a stain on my car roof if u want proof.

  44. michelle says:

    So my question would be what’s the easiest way to clean the soda out of your car…I had one explode and its all over the roof

  45. Kristi says:

    This was my first week of a new job. The new place has a parking lot and I was used to parking in a nice cool garage. I didn’t think about leaving unopened diet coke in the back seat. On my first day of work, I returned to my car (it had been left in full sun for 9 hours) to find coke all over the back seat and the seat backs! The top of the can had been nearly completely blown off the can body, but was still attached by about an inch of seam. The force must have been tremendous. Hope this isn’t an omen!! I am keeping the can on my desk…and also have the stains to deal with!

  46. JP says:

    A few summers ago I was in the kitchen when I heard a bang followed by my car alarm going off in my driveway. I went outside and discovered that the unopened can of diet coke I had left in the cup holder had cooked off and exploded all over the windshield.

  47. JR says:

    Well, I don’t need myth buster to confirm the soda can. Its happened to me, in the trunk and in the cupholder.

  48. keithwins says:

    Re: exploding cola: Wrong question asked and answered. The temperature of a can sitting in the sun in a car is NOT equivalent to the air temperature of the car (which is what they set their oven too). Radiant solar heat could have heated the cans themselves to many hundreds of degrees, depending on the emissivity of their coatings and other specifics of the arrangement.

  49. blessed says:

    I had 4 six packs 1 pepsi 1 diet pepsi 1 mounyin due and 1 sprite in the back of my truck for 3 month. The only cans exploded was da diet pepsi sodas. How do u explain that.

  50. felixnoir says:

    In Queanbeyan, near Canberra, Australia, there is a quite substantial pedestrian suspension bridge over a gorge, similar to the mythbusters bridge but larger. The deck bounces in quite a frightening way, if only a couple of centimetres, when you walk across it. I think the little soldiers used did not have much weight or mass, thus not much inertia. Try putting a couple of rocks over 100 lb on the bridge and then set them bouncing from the side. I think you may well see structural damage to the deck resulting from twisting.

  51. glortman says:

    I was in a mall parking lot near Toronto, Canada, walking past a car when it sounded like a shot went off inside. When I looked to see what made the noise (after jumping!) I saw white foam all over the inside of the car. From the menthol smell, I am going to guess shaving cream. It was hot, but not like Nevada or anything. Myth confirmed.

  52. Darren Forster says:

    After yesterday I was so shocked and can confirm that cans of pop can explode if left in a hot car. Was working on car park yesterday at Goodwood festival of speed, left cans of dr pepper in the car in heat. Went to open one – BOOM! – the metal ring pull blew upwards out of the can, obviously the weakest point, then made weaker at the moment of lifting ring pull. Luckily only just stayed attached to the can. Quite shocking.

  53. Michele Scercy says:

    I had 5 cans of diet Dr. Pepper in the 12 pack box sitting on the passenger seat of my new car. While I was at work today 2 of the cans exploded inside my car- so, yes, it can happen as has already been mentioned.

  54. Bill says:

    I wish y’all would come visit Texas in the summer. It’s nothing new to have a can of coke explode in the car if ya leave it there in the summer. My wife left a brand new 12 pack in the back seat. After coming work she found 9 out of 12 cans exploded! They tore up that box pretty good. Only 3 cans survived.

  55. KR says:

    Oh my, so frozen chickens really penetrate more glasses than thawed chickens? The weapon industry better start producing full metal jackets again, and stop making those rubber bullets…

  56. CHERY GEATHERS says:

    My husband just had a can of Pepsi explode in his face and heat had nothing to do with it. The can was at room temperature ( about 80 degrees) and he was stocking a built in can holder in the refrigerator. There is some impact on the can when it lands on the can beneath. Interestingly, it wasn’t the top that blew off. There was a jagged rent from top to bottom.

  57. Clinton says:

    Both aerosols and soda cans can explode in a hot car.

    1) Personal experience I had a can of soda on my front seat and car was parked in full sun (temp on day was about 35C). Came back to my car to find sticky soda everywhere. Can top had blown off and the bottom piece had ballooned out. Myth totally confirmed in my opinion.

    2) as for aerosols I work for a company manufacturing these. By law all aerosol cans need to be tested at 55C to ensure that they have no leaks and are not over pressured. The cans we use have a burst pressure of about 1400 kPa, and usual pressure of a typical aerosol we manufacture is about 750kPa at 55C. So there is a safety factor built in, but if you store it in an area which can be exposed to temperature > 55C the risk is all yours. I’ve tested cans up to 85C and got internal pressures of around 1300 kPa so this is really pushing the limits of the cans. If there is a slight defect in either the can itself, the crimping of the valve onto tthe can, or the quantity of propellant filled into the can there is definitely a huge risk of exposure. Internal temperatures of a car standing
    in the sun can easily reach 70-80C (on a day when outside temps are 35C)

    For what it is worth I have had a box of safety matches ignite inside a car on a hot day. Luckily for me I went to the car and managed to put the fire out before it got too serious – only melted a bit of plastic.

  58. Mike says:

    Episode 12’s bridge test was a joke. Episode 14 tested and changed to plausible, but didn’t air.
    Given episode 60’s tesla testing with a small oscillator, you’d think the bridge question would be revisited.
    When in the Army, I was in a platoon (approx 40 guys) doing our 15 miler.
    Our Drill Sergeants didn’t put us into routestep as we started to cross a trestle bridge in Ft Sill OK. It started oscillating side-to-side so bad that when we did break step, it was hard to stay standing for a few seconds.
    It didn’t shake apart, but then we didn’t continue once we realized what was happening and stopped our activity, so who knows what would happen if we continued… or worse, if we emphasized our action to see what would happen?
    The issue with episode 12’s test is that they tried to “stomp” the bridge down.
    That’s not the problem with marking troops. It’s the side-to-side shifting of weight that causes the issue.
    Find a nice rope bridge, line up the staff and match across in synch, then multiply that by a bunch and imagine the impact on a more solid structure without as much “give”.

    Sorry, episode 12 always made me scream “are you serious?!?” at the TV, since they failed to see the horrid flaw in their test.

  59. Dan says:

    Not only do cans explode in cars in the heat (the stuck buttons on my radio are remaining evidence), but plastic bottles can get hot enough even just outside. I’ve seen a row of 2 liters of Mt Dew explode while getting gas because the station left them outside for an advertisement display on a hot day.
    The problem is that mythbusters, while a cool show and lord knows I’d love to have their job, don’t know how to account for confounding variables.
    For example, heating a car isn’t enough – the sun’s rays are different than a heater. Then if the can happens to be in direct sunlight, not just the heat, even more energy goes into the can.
    I also got upset at the super heroes episode (first one) where they tested whether a ring could leave an indentation on someone’s forehead when punched. They did well with the mechanic arm and all, but the skin they used not only wasn’t close enough to human, it also was just draped over the head. Our skin’s attached pretty well… If the skin isn’t attached, there’s a lot more give and the force gets moved away, thus no indentation.
    I don’t know if that one would be true or not, but just the fact that they quite often don’t take those things into account.

    This soda can myth is definitely true, keep cans out of car on both HOT and COLD days.

  60. MEKI says:

    My experience just a few moments ago – I have photos and everything – scared the living you know what out of me…
    DR PEPPER CAN EXPLODED – while I was driving 55 — while laying by itself in passenger seat… not even 85 degrees out.

  61. Ryan says:

    (ice bullet)what about putting a metal cap behind the bullet with maybe a post up to the top to keep the weight right.. and freezing the bullet with liquide nitrogen?

  62. Jonathan says:

    We had some pretty insense heat last week here in Chicago, and I had some diet pepsi cans that exploded in the car. It’s strange that a majority of the exploding cans were diet pepsi. I wonder if it’s the ingredients of the diet pepsi that make it more prone to explosion from heat, or if the manufacturer of the cans is producing them to a lower specification.

  63. Ben says:

    Cans can explode if left in a hot car.
    I left a cold, right out of the refrigerator can of sprite in my car on a hot summer day (105 deg) out of the sun. The can had exploded by the time I returned 3 hours later. Sprite was found on the roof, window, and steering wheel.
    It appears the top buckled, creating a crease which looks like the initial point of failure. On the inside of the can, near this point and speckled about, are discolorations and pock marks, like the aluminum oxidized.
    My can may have had an imperfection that allowed the explosion.
    I’m sure you can recreate this guys… Or we’ll have to bust the Mythbusters.

      I had a similar experience, except I was driving to back to college in my 1989 K2500 and it was winter time. The truck was not very air tight, so to keep warm I had to blast the heat all the way up to keep my toes from freezing. I had several Sierra Mist Cranberry cans on the transmission tunnel with some clothes and a pillow keeping them from rolling around. The hot air from the heater was blowing directly on the cans that were insulate from the rest of the cab by the clothes/pillow.

      Long story short, the can exploded and scared the you-know-what out of me. When I got back to college, the first thing I had to do was laundry. The next day I spent an hour cleaning sticky soda from the floorboards, headliner, steering column, etc.

    You guys once again don’t know anything about testing. A can of Coca-Cola can and will explode if left inside the Neon you bought your girlfriend. I know I left on in and had to clean it up.
    The problem with your testing is you never really know what your doing, and never actually have real field tests, just your hypothetical crap that is never definitive.

    I actually had some Sprite from Mcdonalds that I left in my backseat for a month of the summer, and when I came into my car to do some cleaning, I couldn’t find my cup, yet the cupholder was filled with sticky soda. My sister told me the heat exploded it, so I guess it pretty much is real. I’m not sure.

  66. Jasmine says:

    From what I’ve seen from other tests, Sprite would be the kind of soda that would explode from heat, so Mythbusters throw away that Mythbusters cola and test out some sprite.

    A soda indeed can explode in a hot car. I left a can of Dr.Pepper in my tan Oldsmobile Intrigue in the center cup holder was about 95 F on summer day for about 4 hours. I estimate it to be maybe 120F degrees in the interior. The top blew off the can and it took awhile to clean up since it was everywhere.

    I personally witnessed a can explode in a hot car. I was driving, a loose, closed can was rolling around on the passenger seat floor, and when I braked and the can rolled forward, it sounded like a gun going off, and split all the way down the side.

    I watched the aerosol epp. the other night and was so shocked at the result of busted! I personally had an anti-perspirant can explode in my car! I’m in Australia though.

    We just had an older can of enamel spray paint explode in our garage. It was hot and humid. Maybe 100 degrees out. The can had been on there shelf for years but no rust. We used WD 40 to clean the paint off our car. Thank god we found it before it dried.

  71. PeggySue2u2 says:

    I’ve found that in this Texas heat, proximity of window for glare and duration are all variables that induce cans to explode as well as leaking plastic coke bottles.

  72. PeggySue2u2 says:

    Sometimes variables are not that easily recreated. For instance, who would’ve thought that my fence would catch fire yesterday from a spark in the BBQ grill that traveled 5′ to the fence. Thank goodness the hose was in front of the fence for a quick soaking before it reached our homes. :)

    Adding some cotton to the ice bullets makes ice much much stronger. Later when the ice melts inside the body only the cotton remains mixed with the T-shirts cotton. No way to find the assassin :)

    I haven’t had problems with soda and heat, but my dad bought about 4 packs of a dozen sodas each and they have mysteriously exploded in our pantry. It drove my mom nuts, since he didn’t clean up after. We thought placing them in a clear plastic tub would stop it from going on the walls, and it did. Just today, we found out that about 12 entire cans had all burst, all on the bottom of the box. I think it was a simultaneous chain reaction. The only ones that survived were 3 cans of coke zero, which were above the empty cans, and one can of iced tea. There was also a weird powdery blue-gray dust on top of the mix. Our house isn’t extra hot or extra cold, so maybe it was the air pressure? I don’t quite know.

    I wasn’t so lucky. I had a can of paint explode and saturated my car with paint.

    Also, shattered my windshield. It wasn’t even near the damn thing. To bad I can’t post pictures. I got heaps.

    Today a can of Coca-Cola exploded in my car!! please revisit the mith…I can show you the mess in my car :-(

    The aerosol can test makes me doubt myth busters and if they can be bribed. Aerosol cans and bic lighters can and do explode inside vehicles closed in summer heat. Now someone seeing the show could leave wasp spray etc in a vehicle and possibly blind someone !
