Episode 72: Underwater Car

Air Date: January 24, 2007

If a car falls into the water and becomes submerged, you cannot open the door until the interior is flooded.


The pressure differential between outside and inside when the car is submerged is too great for a man to force the door, and the pressure must first be equalized, which means the interior must be flooded first. But it should be noted that Adam was forced to resort to emergency air in his first test. A second test later showed it to be possible to escape the car simply by opening the door, but only by remaining calm and not attempting to open the door until the interior is well and truly flooded, so as to conserve oxygen while holding your breath.

You can escape a car that has fallen into the water immediately after hitting the water.


There is not enough water pressing on the door to keep it shut. Adam escapes easily.

You can escape a car that has fallen into the water as soon as the water inside the car is up to your waist.


Adam barely manages to force the door open and is even briefly submerged before he emerges from the car.

You can escape a car that has fallen into the water as soon as water covers the car window from the outside.


At this point, the pressure differential has become too great. Adam is unable to escape.

You can open a window in a submerged car by using a manual window crank.


Using a test weight of 350 lbs (equivalent to pressure differential from just two feet of immersion), the pressure of the window glass against the frame is so great that no amount of effort can move the gear. You are more likely to break the window handle.

You can open a window in a submerged car by opening power windows.


Though more powerful, power windows still cannot overcome the pressure differential. Contrary to popular belief, though, power windows can withstand immersion in fresh water for prolonged periods and still function.

You can open a window in a submerged car by attempting to break the window using a set of keys.


Window glass is tempered and resistant to impact from blunt objects. Keys are ineffective.

You can open a window in a submerged car by attempting to break the window using a cell phone.


A cell phone is ineffective.

You can open a window in a submerged car by attempting to break the window using steel-toed boots.


Boots are ineffective.

You can open a window in a submerged car by attempting to break the window using a window-breaking hammer.


The device is designed with a pointed tip designed to shatter tempered glass. The hammer breaks the window on the first try.

You can open a window in a submerged car by attempting to break the window using a spring-loaded center punch.


The point of the punch can work like the tip of the hammer, and punches are sold for the purpose of breaking window glass. The punch breaks the window on the first try.

A piece of paper cannot be folded in perpendicular halves more than seven times, regardless of its size.


It was impossible to fold a piece of letter-sized (8.5" x 11", 216 mm x 279 mm) 20 lb (37 g/m2) copy paper with perpendicular folds more than seven times. The thickness of the paper exponentially grew with each successive fold, and after the seventh fold the paper was just too thick to fold without breaking. The MythBusters then laid out a football field-sized sheet of interconnected paper (170 ft x 220 ft, 51.8 m x 67.1 m), and due to the reduction of its thickness-to-area ratio, were able to perpendicularly fold the paper 11 times.


  1. Kevin dipple. uk says:

    Hi there going back to submerged car, the pressure differencial in water is not preventing the window from moving because the window is smooth. when you tested the theory you put weights and sand bags onto a car window in a door on its side therefore the weights and sandbags will not move pass the window frame. You really need to test it on the car in a pool. sorry not being picky but gotto get it right i suppose.

    • Carl says:

      Not really, as it’s not the contact points outside that matter. The pressure of the water is pressing the window against the car’s molding and frame. The point of contact that matters is between glass and car. The weights placed on the window were free-standing, so would not have had an anchor to cause friction to enter the equation.

      • Andrew says:

        Kevin is correct. I just watched the episode again today and it reminded me of a definite flaw in the weight system that he used to “simulate” the weight of the water. The sand bags would obviously cause friction that would stop the window from moving once the sand bag met the lower window frame. When you watch the segment closely, you can notice that the window moves very slightly until the sand bags meet the lower door frame. It no longer becomes a test of perpendicular pressure upon the window, but more of a test of parrallel pressure applied by friction…which totally skews the results. The weights would need to be frictionless in order to not interfere in a simulation that is ONLY supposed to be the effect of the pressure on the window. The added friction is what made it completely inaccurate. A large block of ice would have worked nicely.

  2. jamoecw says:

    he also didn’t use the point of the keys, which would mean less force would be required in order to break the glass, just like the hammer and such.
    also on a safety note, adam didn’t blow bubbles on his way up from the car, which could have killed him due to the expansion of air in his lungs. jamie being a “dive master” should have known this, to me that was the most disturbing thing i saw in this episode, after all if the diferential pressure wasn’t as great (as in if the myth was busted) then the air in the car would have been compressed enough to pop his lungs from about 6 feet (i beleive 4 feet is the record).

    • Tyler says:

      I didn’t see the episode, but exhaling on the ascent is not necessary if he held his breath on the way down from the surface. If, however, he took breaths of the compressed air inside the car once it was significantly compressed, there could have been a problem. The situation was not nearly as dangerous, however, as it would have been if he had been using an air tank.

      • ben says:

        He wasn’t submerged long enough or deep enough to saturate his blood. He was totally safe.

        • Ed says:

          That’s not the point. If you take a breath of air at depth then as you surface the air in your lungs will expand – to avoid serious injury you must breath out whilst ascending.

          If you merely take a lungful of air at the surface, dive to depth then resurface again then there is no danger.

  3. Anon says:

    I thought the same thing about using the point of your keys. It seems like if you use anything to concentrate the force like the hammer or pick does, the tempered glass will shatter. Kicking or punching the window won’t work because underwater there is too much resistance to move your arms or legs fast enough, and a boot will disperse the force a lot more.

  4. Mike says:

    After the Bridge collapse in Minneapolis yesterday this episode seemed to be a bit more relevant. Is there any particular type of window breaking device that works better than the rest (Hammer vs. Spring loaded center punch)? For some reason the spring loaded center punch doesn’t seem as dependable. How about Seat Belt cutting devices in the event it jams or your weight is preventing it from releasing?

  5. Lillian says:

    See lifehammer.com and resqme.com

  6. Lillian says:

    Also found spring loaded center punch recommended for first responders on web site. But the lifehammer and resqme products have seatbelt cutters included. Spring-loaded center punch does not.

  7. James says:

    I found this site through a google after the bridge collapse. If I have a life hammer, I can get out but how would you do it if you had kids in the back? Esp. one in car seat?? I imagine that if you bust the glass, the car would flood with water very quickly. I’ll have to find this episode on iTunes.

  8. Daniel says:


    Get the kids out first.

  9. Mike b says:

    Hi all, being an Australian and living on the driest inhabited continent in the world makes me wonder why you people like to drive into water so much. It would seem perfectly logical to stay the hell out of it if you where in a car.
    Pretty worrying about the standards of your seat belts to. Ours always work even in 30 year old cars.

    • Nicole says:

      Hahaha! There’s always that danger you’ll drive into a pond or flooded roadway though. Happens firly often

    • Melissa says:

      Your comment made me kind of laugh. We don’t drive into the water intentionally over here, LOL! This would be an emergency situation, like if a bridge over a river collapsed while you were driving on it, or if there were a car crash and your vehicle went careening down a slope and landed in a lake or swamp or something. And our seat belts are just fine usually — but again, this is for an emergency situation and if the crash damaged the buckle mechanism on the seat belt causing it to not release properly, it wouldn’t matter how well the seat belt functioned previously. :) Hope that clears it up!

  10. Phil says:

    Being a EMT I know that seatbelt buckles when your in a panic can be hard to work. It’s best to have a seat belt cutter included. Please note, not wearing a seatbelt the impact of your nogging into the windshield would leave you useless. I agree to have kids in hand, cut the seat belt a second time so you have enough to tie your child to you before you attempt to break out. Try not to panic, you will have time to get out and get to the surface for your next breath.

  11. Taylor L. says:

    Adam, and J man, you guys did not test the windshield. If you it the windshield during a (superhuman) panic with the heal of your foot, you can break the windshield. (Foot or boot, or shoe)

    • brokensyntax says:

      Hahaha! Taylor, I challenge you to go stand on the hood of your car, and kick it until your foot penetrates the glass.

      Even trained martial-artists have difficulty with this particular feat of strength; and any I’ve seen try have required multiple hits, followed by IF they managed to make ANY size hole at all, it was only large enough to pass through cutting up skin around the point of entry and then requiring a safety crew to enlarge the hole before extraction of the limb to prevent further damage.

      The issue with the windshield is that they’re designed specifically to not break. They are two layers of tempered glass fused with a flexible binding layer. As your windshield is constantly abused and pummeled in it’s day-to-day uses it is highly resistant to damage by design to protect the occupants of the vehicle.

      • stephanie says:

        brokensyntax taylor may not be right. but you are talking about the strength from the outside of the windshield. he is talking about the inside of it. completely different, a windshield is meant to break and give way from the inside.

  12. Anon says:

    Side door windows can be broken with your elbow, at least from the outside, on dry land. I saw a thief do it right in front of me. The window broke on his third strike. Then he stole the purse from the front seat and ran.

    • slade says:

      you couldnt move your elbow with wnough velocity underwater to break a window. unless you have a spring loaded elbow.

      • Emily says:

        You wouldn’t be moving your elbow through water if you were inside the car and trying to get out.

  13. David says:

    With reference to submerging a car in water and being able to opent he car door submerged.

    I Have seen this experiment undertaken by TopGear; a vehicle program on the BBC.

    They found that while the car was sinking the pressure did not equalise until it had reached the bottom and rested for a few moments.

    They indicated that as some lake/lochs can be quite deep in Britain and holding your breath until this process had completed would make survival unlikely. The best cause of action was to get out asap, before the doors became submerged.

  14. michael says:

    I was an autoglass installer for 11 years and can tell you that a door glass can be broken with a set of keys by rubbing them firmly in one place. deepen a small scratch and the temper will do the rest. I have done it in the dumpster at work just for fun with used windows.

  15. Natalie & Owen says:

    Hello from Australia! We were wondering about the effects of salt water on the electrical system of the car. Would the salt water short out the system more quickly than fresh water? We also have to agree with kevin from the u.k regarding the weights on the window. Lets repeat the experiment with a car with electric windows in both fresh and salt/sea water. please. We love your show, keep up the great work guys!

    • slade says:

      I agree with the manual window opening. It will open. With the 350lb weight they are using a completely different example of torque than if it was under water. They didnt test it underwater even though they had a car with manual windows underwater numerous times. Leads me to believe it was a decision by the produces.

  16. Greger R says:

    Hello from Sweden! I think that the mythbusters have missed a possible tool for escaping a sinking car, namely the seatbelt latch plate (the metal plate that you push in to the seatbelt mechanism)! It’s always where you can find it and if you close your hand around the plastic covered back part and let the metal part stick out through your fingers, you can use it as a glass breaking device! I wish I could get the busters to try that!

  17. Ferus1920 says:

    You busted the paper myth on a technicality. The football sized sheets you used were taped together changing the properties of the paper. Increasing the size without increasing the thickness is also unfair. The original myth refers to a standard sheet of paper. With the way you tested it you might as well have used tissue paper.

  18. Norman says:

    I just lost a friend who was unable to get out of a submerged rollover in water. I am researching this subject and have a post on the Halfbakery regarding this subject. Lots of good advice here, thanks.

    I’ve heard that they’re beefing up windowglass to make theft harder. If this is so then a lot of this advice will not work.

  19. emil says:

    in your show “underwater car” you busted the mytin wich you can open a window in a submerged car by attempting to break the window using a set of keys, but you’ve made the attempt to break the window, with a submerged door thou, in a real car when it’s underwater and the interior it’s not filled with water the presure on the window can cause it to break more easyli when hitting it with a key, so I think that you should try it again.

  20. Fred E. says:

    Okay Adam, I’m late to b**ch (saw a repeat)! However, when you tested rolling down a window (powerd OR NOT), you forgot about friction! TEST IN WATER!

    • slade says:

      Agreed, water against the window will have little to no friction. They had a manual window car underwater numerous times the whole show and could have tested it but decided not to. I think this was a decision by the producers of the show. Maybe to help sell window breaker hammers.

  21. kyle says:

    Iloved this episode

  22. Kusumura says:

    “Taylor L.:

    Adam, and J man, you guys did not test the windshield. If you it the windshield during a (superhuman) panic with the heal of your foot, you can break the windshield. (Foot or boot, or shoe)
    August 14, 2007 at 10:31 PM”

    I agree. Although I doubt it would have a difference, in a panic I’d be smashing at my windshield as though my life depended on it. Lol.

    • Dallas says:

      Windshields are laminated. You could potentially break it, but you’d never EVER get through. Go ahead and try with a sledgehammer – with a sledgehammer, you might get a fist sized hole, and the average person would need a few swings at that.

  23. Brian says:

    Blew it on the window thing, folks. EITHER you have differential pressure, OR you have water in the car slowing your hits. Not both. So, if there’s water in the car, roll down the window because there’s no diff pressure. Otherwise, hit the window.
    Really should have caught this, guys.

  24. Tom says:

    On the power windows problem, Kevin is right. You could see in your video that the weights against the frame were preventing it from moving, not merely the pressure. Both were probably at work, but I think the power window might have opened without the frame interference.

    Brian (Jan. 30) makes a good point about water pressure. But we already know if you wait until pressure equalizes, it’s too late. The question is, can you open the window before you can open the door?

    And, as some suggested, you can probably more easily break the window win the pressure is not yet equalized. But do you really want bits of glass pushed into your face by 300 pounds of water pressure?


    • Sarah says:

      I feel like bits of glass in my face are preferable to drowning… just saying.

  25. mATT says:

    I accidentally discharged one of those pointed window punches while holding the thing in my hand, with my thumb over the pointed end. It didnt hurt. I doubt its ability to break glass if it couldnt even puncture the soft skin on my thumb! I’d just get the metal seatbelt buckle (since its always readily available) and punch the window with it.

    • Sarah says:

      I did it once too, but it punctured my thumb. However, that’s irrelevant. It’s not meant to puncture the glass, it’s meant to resonate at a frequency that shatters it.

  26. Lance Brydges says:

    For those of us who have had someone we know suffer this tragedy it is good that all avenues of this myth be tested and the public informed. An episode like this took place right near our home and on a road that we travel often. We still shudder when we pass the spot.
    I watched an episode on “Daily Planet” where they interviewed a scientist studying this topic and his instructions were to exit the vehicle as soon as possible. He estimated that if it was not done in the first 90 minutes, that the outcome would almost always be tragic.
    Car industries should get involved in this as well. Maybe making those little bottles, Adam had as backup air, affordable and accessible to the public would be a good idea.
    Keep Busting!
    Namarie an si

  27. Madison says:

    for jamoecw, its true about blowing bubbles on the way up, but thats if you are breathing compressed air from a scuba tank. if you take a breath of air at the surface and dive down, your lungs compress as the pressure increases. since you are holding the same air as on the surface, your lungs expand back to normal size on the way back up. hence freediving. IF you breathe from a scuba tank at depth, your lungs return to the size they would be at surface. this is where it can get dangerous. as you ascend, air expands. after breathing compressed air ,if you ascend and hold your breath your lungs will over expand and potentially pop (bad). also after breathing compressed air and ascending too rapidly, you could cause an air embolism or DCS.

    for lance, pony bottles (the little bottles of back up air) are available to the public, but because of the aforementioned potential dangers, as well as other things to keep in mind, you really should get scuba certified first. scuba diving is a lot of fun, and easy to learn.

  28. Zeph says:

    Go for the side windows, which are tempered glass (shatters into not-very-sharp fragments) – NOT the windshield (which has tough flexible plastic sandwiched between glass). The windshield deforms but still traps you in the car.

  29. Trent says:

    I am with Fred E. It was quite obvious that the weights on the car glass window were hitting on the bottom of the window and the friction was stopping it from moviing. If this were done with water there would be no hitting from this.

  30. Dianne says:

    I too, am thinking about getting the children out. Being a mother with 4 kids I usually have 3 belted in the back and one in the front. If I got out but couldn’t save my kids I would rather be dead too. So, how do you get everyone out safe?

  31. Rajn says:

    Just a comment on the power windows myth.

    If I remember correctly, they used weights to simulate the pressure of the water pushing down on the power window. The power window was not able to open because it would need a great deal of force to slide the weights sideways due to friction.

    I hope Mythbusters revisits this myth.

  32. Tom B says:

    1) As water pressure increases and water infilitrates the vehicle, if there isn’t a good escape route, the air will be compressing. So, if you are breathing this air and then exit the vehicle, one would imagine there is a chance of a problem.

    On the other hand, you’ll have no real chance to tell if the air is escaping or compressing. Also, since it takes 33′ (10m) to generate 1 ATM of pressure differential (in freshwater), if you’re only down 3-4 m, you’ll probably be okay in any event. And even if you did suffer some damage because you held your breath after breathing some compressed air and came up from a notable depth, you’d still be better off than drowning as long as someone could adminster oxygen and they could get you off to a hyperbaric chamber soonish.

    Still, it won’t *hurt* you to slowly exhale a small stream of bubbles as you ascend. Small bubbles, slow stream to give you time to get to the surface.

    2) The lifehammer and other similar things work on the idea of force applied over surface area of application. They apply very large forces/unit area because of the sharp point of their delivery. Keys might work, but try punching a board with your keys point out. It’ll probably do your hand some damage. Better to have a reliable rescue tool. At $15, you can’t really argue against the value if you ever need it.

    3) To be safest, get some training from your local FD or paramedics on vehicle extrication. Hard to practice if the use of the tool cuts belts and smashes windows, but you should practice unbelting, acquiring the tool, and the rough motions with the eyes closed. Extricating yourself through a window could be challenging for some if they are short like me and fit tightly into place – I’d want to tilt the steering away and move the seat back if possible.
    Getting out through a shattered window is a bit like a wet exit in a flipped kayak and that’s a bit exciting if you’ve never done it for real before.

    4) Seatbelts, if you are hanging upside down or they’ve taken some damage, may jam. You might not be able to unbuckle, thus trapping you and/or preventing you using the seat belt as a hammer. Something like the lifehammer or resQme should be within *arms reach while belted*. Then you can cut away (probably that would be exciting if you’re upside down also… fall on head on car roof in confined space won’t be fun, but it will be necessary).

    5) Pressure outside from water is both good and bad. More of it means likely more water pushing into the vehicle from any point it can intrude (eventually any seals will fail). But it also means that the pressure on a window to fail is greater, so a smaller crack in the glass should yield window disintegration. Of course, the more water pressure, probably the more cold (from depth) and force (in your face) you’ll face when the window goes. Nothing like being kicked in the head by a wall of water… so get out sooner rather than later. But if you have no option and are submerged, probably face away from the window, put your chin on your shoulder to stabilize your head, and shatter the window. That’s the best chance of not getting knocked out or stunned by an inrush of water at significant depth I’d imagine.

    6) If all else fails, try keys, try seat belt edge, if you’ve got a brass-barrel or steel-barrel fountain pen, use that to strike the window – anything that can help generate signifcant force on a small area (hatchet, knife point for hunting or pocket knife, etc).

    Failing having any tools, if you can get a forearm lined up, try to strike hard with the tip of the elbow, moving from the shoulder with your body weight. Or fold your fingers at the second knuckle (tiger’s paw) and drive with that – likely to break some knuckles, but it might crack the glass. These are VERY desperate measures – far better to have the $15 lifehammer.

    No, I don’t work for these guys, I just recognize a key safety tool for a good price.

    And remember, the best lifesaver in a crisis is not panicking – immediately focus on the critical next step to saving yourself, don’t think about anything else, and act swiftly but deliberately. Deliberate action, a cool head, and a focus on ‘what do I do next?’ is the best odds of coming out in one piece.

  33. Casper Andersen says:

    About the big piece of paper. You took normal-size thikness in paper (A4) and strecthed it! It is not possible to fold a piece of paper more than 7 times if you use the same scale every time you try folding it! It’s what a wise man once said: “for every action, there’s a re-action”.

  34. Logak says:

    Casper: That wasn’t the myth. The myth was “a piece of paper cannot be folded more than seven times regardless of size.” The fact (if it is) that a matching-scale paper wouldn’t get more than seven folds is irrelevant; the myth was talking about any paper of any size, and was clearly busted.

  35. Seth says:

    I never heard a mention of the air pocket in the rear of the vehicle that can be used while waiting for pressure to equalize. Also I would have definitely punched out the window with the point of the key, and yes, windows should still work underwater.

  36. Jessica says:

    K,so I know that it is not completely relevent to the whole car and water thing, and I have no idea whether it has been done or not, but I was wondering if you could test which boils faster: cold, hot, or salt water. There has been some debate amongst me and several I know and I’m dying to have it answered.

  37. KatetheGreat says:

    Along with the other parents who have previously left comments, I am terrified at the thought of being in a submerged vehicle with my child strapped in a carseat behind me. I don’t know if it would be a good idea to revisit this myth using a Buster Jr. or if it would be too disturbing for viewers. I guess it would all be a matter of timing once you hit the water as well injuries being a factor, but I’m no rocket scientist.

  38. Billy says:

    I’m all for being prepared when it makes sense, but you have to weigh the cost of preparing for something vs. the probability of it occurring. You don’t just drive into water every day. You may say it’s worth a few days of research and preparation to be ready for it, but there are plenty of scenarios that are just as dangerous and much more likely to occur. Are you going to spend a few days on each of them?

  39. Paul says:

    It is good to know how to get out of submerged car.
    Based on the few comments from people with children it seems that chance for survival with children may be much lower for both parent and the child due to “parental panic”.

  40. Jeff says:

    I was a towtruck driver for many years. I towed publiclally and for ins companys. Once in a great while it became necessary to break a window. Like I said, not often, but in very certain cercumstances. This is how I did it. First of all, big hammers don’t work without beating hard on the window repeatedly and making tons of noise, forget that. What does work: Carry a leatherman or any other similar tool with you. Stick the pliers or whatever you have down under the rubber on the botton side of the window, preferably near a lower corner. Now pry. The tool chips the tempered glass and it instantly spiderwebs very silently and easily. Do not try this for any illegal purposes. I just wanted to prove that it is very easy to do if you know what you’re doing, and only if you need too. Works just as easily underwater.

    • Dave says:

      If this advice was not for “illegal” purposes, why did you mention that hitting with a hammer makes “ton of noise.?”

  41. Phil says:

    *”You don’t just drive into water every day. You may say it’s worth a few days of research and preparation to be ready for it, but there are plenty of scenarios that are just as dangerous and much more likely to occur. Are you going to spend a few days on each of them?”*

    Sorry, Billy? What’s your solution? Ignore them and be unprepared if they do happen? Considering that this is really only costing about $15 for a hammer to break the glass, and possibly something to cut the seat belt, I don’t see the cost outweighing the benefit. Far better to be prepared. Especially since those items would be just as handy if you were in an accident and your car was on fire.

  42. Rob says:

    Drive a convertible

  43. Ian says:

    I just saw a programme where Bear Grhylls put his belt around his foot with the buckle on the sole and smashed the window with a stamping motion…but I’m not sure if it was true or fixed. I reckon the Mythbusters should test some of these survival myths like the time Grylls gave himself a seawater enema to rehydrate himself on a desert island. Would it really work? Or when the guy died after a few weeks from eating rabbit because there wasnt enough vitamins.

  44. Yossarian says:

    Also on Worst Case Scenarios, Bear Grylls tested this but used the head rest to smash the window as the two prongs had a small surface area.
    He also recommended not undoing your seatbelt until the water on both sides equalizes unless you want to get buffeted around by the water. There was an exception of course, being if you could open the door early enough to get out.

  45. Laura says:

    I am also interested to know if the prongs of a headrest would break a window. You always have that available in a vehicle. That still leaves you with the trouble of a jammed seatbelt. I noticed when this myth was revisited and the car “turned turtle” that the saftey diver had to cut his seatbelt off. This might also be necessary if your car was on fire. Thanks for all you guys do on Mythbusters!

  46. Derek says:

    what was the name of the air tank they used inside the car that made no bubbles, it turned your breath into breathable air

  47. Chris says:

    Has anyone ever tested opening a sunroof? A sunroof has a tilt operation, which may be enough to at least provide a little crack to equalize pressure. What is more, the mechanism on a sunroof slides the glass very differently than on the door windows. Perhaps the sunroof wouldn’t get stuck the same way a door window would trying to slid against all that pressure.

    Additionally, why is it that no water is gushing in through the HVAC system in cars. If they are set to pull in fresh air there should be all sorts of water coming in.

    And if automakers were smart they would include a valve or seal of sorts that would blow the glass or some panel if the pressure differential gets to a certain point (a few feet of water even). That would make all this discussion pointless.

  48. Max says:

    @ Kevin dipple. uk
    It’s not about the friction between the water and the glass. The water just pushes the glass against the ‘chassis’ of the car. The friction is the friction between that window and the car that it gets pushed against. So the texture of the object that pushes against the glass will not matter.

  49. henry says:

    Well this not a reply to episode 72, but I am woundering if someone can slam a car door so hard that the window shatters, if the mythbusters can bust this myth for me it would be greatly appreciated. Thank you

    P.s I love the show please keep up the good work.

    Sincerely henry

      I actually had that happen to me. The car had just left a heated garage to the cold winter air and the heater was going full blast inside. I got in, slammed the door and the entire winder shattered. Maybe the window was already defective in some way, and the temperature differential weakened it more, but it did happen (I had to pay for the bloody thing).

    About the paper folding myth: I was always under the impression that the “7 folds” stipulation was based on actual creased folds, not just layers. I’ve always been able to “bend” the paper over itself more than 7 times, but have yet to actually CREASE the folds more than that.

    ok.. so being the mom of 2 young boys, what woudl you do if you knew you were going into water….? put the pwr windows down as fast as you can.. if possible? if not, i have 2 boys, and a window hammer..cut the belts, bash the window out ASAP?
    wait . . . ? how do you get out of a window with the water rushing in? wait?
    if possible.. in somewhat perfect scenario, step – by step – what would you do with 2 kids? i would like to be prepared – though hope i never need to

      I am terrified of this happening! I hope someone comes up with something. I have a panic attack every time I travel over water with my two toddlers!

    Yes, I think they should redo the car stunt and try opening the window under water for real, and not just in laboratory with the weights pressing against the window seal.
