MythBusters Episode 50: "Bullets Fired Up"

Air Date: April 19, 2006

Bullets fired into the air maintain their lethal capability when they eventually fall back down.

busted / plausible / confirmed

In the case of a bullet fired at a precisely vertical angle (something extremely difficult for a human being to duplicate), the bullet would tumble, lose its spin, and fall at a much slower speed due to terminal velocity and is therefore rendered less than lethal on impact. However, if a bullet is fired upward at a non-vertical angle (a far more probable possibility), it will maintain its spin and will reach a high enough speed to be lethal on impact. Because of this potentiality, firing a gun into the air is illegal in most states, and even in the states that it is legal, it is not recommended by the police. Also the MythBusters were able to identify two people who had been injured by falling bullets, one of them fatally injured. To date, this is the only myth to receive all three ratings at the same time.

Vodka can remove poison oak.

busted

For some reason, although most of the MythBusters were allergic to poison oak when they were young (especially Kari, who was exempted from the test because she had once had a dangerous reaction), it didn’t affect anyone but John the Researcher. The vodka still gave no results.

Vodka can painlessly remove plastic bandages.

confirmed

Both a control and vodka-soaked bandage were quickly removed from hair-covered legs and, while not painless, the vodka-soaked bandage came off less painfully and removed less hair than the control.

Vodka can be turned into high-quality vodka through charcoal filtration.

busted

Through a double-blind taste test, the cheap vodka seemed to taste better with every subsequent filtration, although the top-shelf vodka beat them all. However, a chemical analysis showed no actual difference between the filtered and unfiltered cheap vodka.

    dear mythbusters, im an ialian fan and i watch our episode on discovery channel. i love our program, and i have a suggestion for revisit the myth: bullets fired up. you create a long tube (50 or 75 meters) and plant it in the desert with a 44 magnum or a revolver .38 over the tube….
    you shoot and when the bullet fall down calculate if the fall is dangerous for the umans. please say hello at adam, jamie, tori, kari, and grant….
    W mythbusters…
    P.S
    revisit my myth please
    thanks

    Hey guys, Your bullet in the sky repro failed to figure in the spin ! the .30 M1 Garand you used had a 24″ barrel and a 1/10 twist. So figure 2400 fps 2400×12/10*60
    is about 172,800 RPM ! You do know that the bullet is still spinning when its on the way back, dont you ?

    I also heard that there was a substantial difference in lethality between high-velocity and low-velocity rounds….can the mb’s confirm? I was told that high-velocity rounds would remain lethal after being fired high in an arc, but low-velocity (44 mag., et al) would not.

    a revisit would be very nice…

    You’ve done dropped pennies, dropped bullets… the mass problem means these aren’t lethal. At what mass does something dropped from a tower/high building become dangerous? Bricks, for instance, I would think would be a real issue. Certainly watermelons and champagne magnums (as seen on Letterman) would be dramatic.

    Here’s a story that should change “Bullets fired into air…” rating to confirmed:

    That msnbc link can’t confirm anything. There’s nothing to say that those bullets were fired straight up in the air.

    I heard the story that the Poms used to do a check fire when they had a new batch of
    artillary shells.
    They would take one of their guns down to the beach, point the barrel up vertically
    and pull the trigger.
    They reasoned the only place the shell
    wouldn’t land was back down the barrel,
    so they wore their tin hats and camped as close the the gun as possible.

    Filtered Vodka

    In wartime France, the fuel if you could get it ,contained a large quantity of alcohol.

    Bloke I new used to extract the alcohol and
    Drink it by passing the fuel through a carbon filter.

    Errata Filtered Vodka

    To be more accurate you must first add water to the fuel.

    This causes the Alcohol to separate out from the mixture.

    You can then decant and carbon filter the alcohol.

    In Australia you can buy fuel that is ten
    percent alcohol.

    That translates to 0.8 of a pint of 100%
    alcohol to a gallon of fuel.

    As normal spirits are only about 40% by volume alcohol that translate to two pints
    of drinking alcohol per gallon of fuel.

    Starts to make a trip to the gas station
    an economic opportunity!!
