Will ALL bullets tumble & if so, why?
Do ALL bullets tumble when they are fired? If not, why not?

Those questions are answered in the same episode.

Download and watch it, then explain why they're wrong, or forever stay ignorant.

^^ Eh?

Could have showed them to that lard arse BBC reporter,you can't miss him ,how he keeps running around I don't know.

No need for insults.

Actually we dealt with that kind of stuff in my first year at University. Mythbusters is fun to watch, but has a huge amount of error in their experimental approach. That's one of the reasons I stopped watching it. A lot of it is rubbish - good for TV, & that's about all.

(I'll stop here as I really don't want to ambush the thread any further)

all rounds are fired at a parabolic trajectory - even those fired vertically - don't forget the speed you are moving at sitting on this ball of rock

Sure he is...just saying I bet thats hard work running around in this heat.The BBC are ok ,just ok though.

The Straight Dope: Can a bullet fired into the air kill someone when it comes down?

Dear Cecil:
Every so often you see it on the news: streets full of Middle Eastern men indiscriminately firing guns straight up into the air. If I learned anything from physics class, it's that what goes up must come down. I'm certain the returning projectiles don't float harmlessly to earth and wonder how often they plunge into bystanders.

Cecil replies:
Those Middle Eastern men. You want to shake them and say: Guys! Is this the safe and sensible way to celebrate? Can't we just say "hooray!" and "whoa, baby"?
But you raise a good point. How dangerous is this really? The question is controversial. Let me lay it out point by point.
Datum 1. At first I thought being struck by a bullet falling straight down would be no worse than getting hit over the head with a two-by-four — not the average person's idea of fun, but not fatal either. What goes up must come down, but it needn't do so at the same speed. You run up against what's known as "terminal velocity." A bullet fired straight up will slow down, stop, then fall to earth again, accelerating until it reaches a point where its weight equals the resistance of the air. That's its terminal velocity.
For further insight, we turn to Hatcher's Notebook (1962) by Major General Julian S. Hatcher, a U.S. Army ordnance expert. Hatcher described military tests with, among other things, a .30 caliber bullet weighing .021 pounds. Using a special rig, the testers shot the bullet straight into the air. It came down bottom (not point) first at what was later computed to be about 300 feet per second. "With the [.021 pound] bullet, this corresponds to an energy of 30 foot pounds," Hatcher wrote. "Previously, the army had decided that on the average an energy of 60 foot pounds is required to produce a disabling wound. Thus, service bullets returning from extreme heights cannot be considered lethal by this standard."
If 30 foot pounds doesn't mean much to you, the bullet made a mark about one-sixteenth of an inch deep in a soft pine board — about what you'd get giving it a good whack with a hammer. Note that we're talking about bullets shot straight up. If the bullet is fired more or less horizontally, it may not lose much speed before returning to earth and could easily kill someone.

Why arent you out filming and interviewing the rioters for Scampy TV then?

^ I called him and invited him and he told me something like his video camera was not good for this sort of thing or her was too drunk or something like that.

He said Butterfly was a twat as well and I agreed!!!

agreed. fun show but definitely flawed. in their defense though they do need to add entertainment value

a poor workman blames his tools....

Looks like this bloke caught this one just in time. Try catching it in your teeth next time mate.



One of the shots taken from the BBC news photo montage of the protest:-

BBC NEWS | In Pictures | In pictures: Thai crackdown

I bought my niece a battery powered whale with a waggly tail from a stall on Suk. It has a blowhole and a ping-pong ball sits in the stream of air air and balances perfectly at its terminal velocity. I would be tempted to try an experiment involving an AK47 cartridge I picked up in Cambodia except my niece might swallow it.

Gordy is banned I think but he says, why don't you wusses all get off your arses and stop talking about it and go down there and throw rocks at the police?

Falling bullets !
I was working, and marooned, at Basrah Airport during the Iraq Iran conflict. The airport was a no fire zone 'cos both sides wanted to have it complete !
Incoming 'spent' bullets were a daily hazard !

Only one chap had a direct hit from one travelling fairly flat and that only just broke the surface of the skin on his back . A few broke windows but the majority were coming in just about vertically.
A construction style hard hat took care of those on your head but if one hit an unprotected area it was about the same as being hit with a pebble from a slingshot - made your eyes water and left a nice purple bruise !

anyone mentioned the myth about a penny dropped from the Empire state building being able to kill??

A coin will have a lower terminal velocity then a bullet

erm, you are being silly now.

Bullets fired from a rifle will spin because of the rifling of the barrel ie the subtle twisted grooves in the barrel of the rifle (I think it is 7 twists for an M16) force the bullet to start spinning as it leaves the barrel.

without the rifling in the barrel a bullet cannot spin of its own accord and thus will tumble - that's why a gun eg: shotgun fires pellets in a spray. and is less accurate as a result.

fuck this terminal velocity mumbo jumbo shit...

will it kill or not?
