Question 1: If you are a happy arab, and you fire your gun up in the air, will the bullet kill someone when it eventually comes back to earth?

Question 2: How does Superman shave?

Probably more to come.

Question 2: How does Superman shave?

Pretty sure he ask Wolverine 

[redsniper]

Question 1 handled by mythbusters. A bullet falling straight down at terminal velocity probably won't kill you. A bullet fired up at an angle though can easily still have enough horizontal velocity to **** someone up.

[Mongoose]

Yup.  If you fire it at an angle, it maintains its spin, and therefore its ballistic trajectory.  Straight up, the bullet tends to spin out and start tumbling, which means it probably won't give you more than a bruise if it hits you on the way down.

It's raining 7.62mm FMJ Hallelujah!

[Colonol Dekker]

Who decided one day......that white stuff coming out of that cows udders,....i think i'll try some of that

[Mongoose]

I think the more pressing question is...who decided to try eating that round white thing that came out of a chicken's ass?

Seriously? As a mammal that should be pretty obvious. 

[Flipside]

Not to forget... 'Hmm... That milk is so rotten it's gone solid. I wonder what it tastes like?

So annoyed I missed this

[karajorma]

Well I'm back home next month, so we can have another one.

[Flipside]

Sounds like a plan to me, and this time I'll sort out some kind of contact number so I can call someone if I get lost... The problem is, I think, that Charing cross has several exits, I think I came out one of the side ones and headed toward Shaftsbury Avenue, but there's so many theatres in the area that I had no idea which one I was actually looking for, I could have used those street maps more effectively if I'd had a name.

[Colonol Dekker]

Palace theatre, ask newspaper sellers. Them's the experts

[McCall]

Well I'm back home next month, so we can have another one.

Beers in London or a re-run of last year's BBQ?

[McCall]

Question 2: How does Superman shave?

Pretty sure he ask Wolverine 

How about all those hairs up his nose though? I've never seen the Man of Steel with crusty nose foliage, so he must get them out somehow.

Would plucking work?

[redsniper]

Yup.  If you fire it at an angle, it maintains its spin, and therefore its ballistic trajectory.  Straight up, the bullet tends to spin out and start tumbling, which means it probably won't give you more than a bruise if it hits you on the way down.

Er.. well... it's not the spin that matters so much. Objects are going to move in ballistic arcs regardless of how they're spinning. If you chuck anything straight up, it's going to come back down at terminal velocity. If you chuck something at an angle, the vertical component of it's velocity will be reduced and then go negative (it falls down) because of acceleration from gravity. The horizontal component of velocity only has air friction acting against it, so it won't slow down nearly as much, so the projectile could still be moving dangerously fast. [/HerraTohtori]

[Scotty]

The difference being that a bullet fired straight up loses its spin during the negative acceleration due to gravity.  A bullet traveling horizontally loses much less of the spin, and maintains a not-insignificant aerodynamic advantage over the vertically fired bullet.  When the spin is removed, the bullet begins tumbling, which sharply reduces the terminal velocity on its way back to the ground.

[NGTM-1R]

Mind you, if the difference isn't sufficient to reduce the velocity of impact enough, a tumbling round will simply do more damage rather than less.

[karajorma]

Well I'm back home next month, so we can have another one.

Beers in London or a re-run of last year's BBQ?

I could do either to be honest. Been a while since I did beers in London though.

[Scotty]

Mind you, if the difference isn't sufficient to reduce the velocity of impact enough, a tumbling round will simply do more damage rather than less.

Considering the increase in surface area upon which air resistance and friction is now acting is increased by at least double and depending on the bullet up to fourfold, the difference is quite significant.

[NGTM-1R]

It's also tumbling, so it's not presenting that surface constantly, thus making your argument more impressive than reality.
