Is it me or in the second video with the 40 cal...where they shoot is in front of them yet the bullet that actually spins looks like its right next to them?

apparently the bullets bounced off of the ice into a different location.

I'm not entirely convinced that this is real either. That's why it's up for discussion.

No doubt about this part, but notice the odd trail leading up to the bullet in the second video? How did it maintain its rotation speed as it even shallowly gouged its way through the ice and snow on the way to that spot?

I'm not saying it's fake, but I've fired hundreds of rounds of almost every caliber into the ice over the years and never seen anything like that happen. Who knows.

It's pretty cool to see the bullet spin that's for sure....In the comments on the vid, they discuss Mythbusters. It would be cool if they actually do test it haha.

Perhaps I'm missing the obvious, but how does a bullet fired into solid ice show zero deformation?

Seems more than a little sketchy to me.

I agree. It would seem to me that
a) the bullet doesn't deform because it hits a soft medium (slush or snow) and would penetrate. It would eventually hit a hard medium halting it suddenly (go to b) or loose all its energy, coming to a rest (both laterally and rotationally).
b) hit a hard surface which causes it to stop and not penetrate (in which case it would deform).

I can't imagine ANY scenario where the bullet's lateral energy would be completely sapped but it would retain all of its rotational energy. However, I've watched more than my fair share of Mythbusters so I'm aware that in crazy circumstances, crazy, seemingly impossible things can happen.

definitely fake.

Okay, I just saw the video where they demonstrate it. I hadn't watch that before.

ASSUMING it's real, it appears that the bullet is shot at the ice at an angle where it digs out a divot (transferring much of its lateral energy) which (given a precise angle) ends up launching itself up into the air at a speed slow enough that when it falls to the ice again, it doesn't penetrate. With a soft enough medium at the right angle, I guess it's feasible that much of the rotation might remain.

I'm still dubious but I guess the ice could be soft enough to refrain from deforming the bullet.

In one Mythbusters episode, they try to reproduce the 360 degree ricochet (bouncing off 3 steel plates), a vertical shot with the high-speed showed the bullet flying towards the first plate in maybe 1/2 second, flying to the second plate in maybe 4 seconds, and taking a good 10-15 seconds to hit the third plate (after which it went painfully slow). So it's obvious that such a radical change in direction (close to 135 degrees or more, it looks like) would sap a lot of velocity from the round.

I'd still love to call 'fake' on this, but I wouldn't have my mind blow entirely if I found out it was real.

hmmm shoot water it deforms shoot solid water no deforming ?
