Yeah, I'll third/fourth/fifth/tenth that - this was fun. Keep up the good work! How would you actually curve a bullet? It's an unpowered projectile with a fixed velocity in the x and y directions, while only being acted upon in the x- and y-vectors of direction by air resistance and the acceleration of gravity respectively. | |
I'm a mech eng and physics graduate do your worst ;P Now I'm tempted to figure out how much the answer changes when you take the pressure falling as the bullet fires into account... | |
It's F=m*a, not F=M*A That would be Molar Mass times Area... which will lead to weird results. I wouldn't think Einstein did those kinds of mistakes... | |
Yes yes yes | |
If the bullet had an uneven cross-section you could certainly make it curve by having different drag amounts on each side. The tricky bit would be making it curve in any reliable direction. You'd need a gun that wasn't rifled, so the bullet didn't spin, and you'd need the bullet to be placed in the barrel in the correct orientation. Nothing theoretically impossible, but getting any kind of accuracy would be unlikely! | |
you should do an episode form these scene. (coulndt find the video as such) | |
That would be an interesting one :) although it does seem pretty unlikely... | |
They didn't say "penetrate his skin" they said it would break the skin, just like getting hit by a baseball can break the skin. As for the bullet shape, if you see the diagrams they use, you can see how wide a .45cal round is- and of the most common loads, a standard 230gr ball round, or FMJ, is pretty much spherical at the front, an SWC round has a flat nose with only a bit of taper at the sides, and the hollow point shown in this video would probably tear the skin a little at the velocity shown, but is definitely not carrying enough energy to penetrate more than the depth of it's hollow sides (and that's granting a perfect shot on skin without deflection from clothing, and would definitely not have enough energy to expand. The .45cal round is more akin to throwing high velocity heavy chunks of material at people and relying on raw punch than most other calibers which rely on a ballistic design to maintain velocity and penetrate, causing tissue damage through a wound channel via hydrostatic shock. | |
I'm not really contributing to the thread, but just wanted to say this is the best episode I've seen for a while, keep up the good work! | |
Must've understood it differently then.. I thought if you broke the skin you pretty much penetrate it, but perhaps my English isn't up to snuff on that one. | |
This is quite literally a case of "a wizard did it". | |
What DanHibiki said. Also, the book is better. | |
Excellent show. I loved Shoot'em Up. Well, basically I love Clive Owen. Still, it was a great piss-take film as you rightly pointed out in the beginning. It would have been interesting to find out just how long it would take for the bullets to spontaneously fire in the flames, but enjoyed this, and all your other vids very much. Cheers! | |
Another fantastic episode. I just remembered, that scene with John Malkovich as a retired officially dead government black op in R.E.D. where his revolver shoots through an RPG and blows the woman to bits? I'd love to watch if that is even physically possible, accuracy aside. That movie is chock-full of scenes worthy of your episodes, by the way. | |
lol. never read the book. dint even know there is a book of it. still enjoyed the movie though. but you have to admit, it still would be a funny scene to show. | |
Abell beat me to it. The "chamber" pressure will defiantly go through the soft brass case. It would not be a mini shrapnel grenade, but it would be more like a zipper. I have seen pistil and rifle ammo do this. I have a few hand loading friends and with my loading experience we have seen out won share of catastrophic failures. The "slow burning smokeless powder" still burns extremely fast and hot. That spurting of hot gases pouring out a split in brass would severely jeopardize those soft fingers. | |
The mythbusters tried that, the answer is no. | |
I have a request for a future episode. Will Meg Ryan ever find true love?
Shoot em up is not a plausible film, it is however, a superb film. You think you know what will happen but it just gets crazier as the film progress. | |
The movie is an adaptation, and seeing as the book is a massively dense brick of political intrigue and philosophical discussions about what really differentiates "good" from "evil" and how arbitrary the designation ends up being it can't possibly measure up. The book is in fact so good it makes me very sad that I can't read Russian because in places it really feels like something is lost in translation. | |

Just wanted to say great show and thanks for doing it!
