These guys are absolute morons and its only a matter of time till one of them is hurt. Do to some language ONLY the link is posted

"I dont care if I get hit"

While stupid, I assume he meant he didn't care if he got hit by the ice that flies back.

I sure hope that's what he meant.

I found this MythBusters thread about it.

One would hope but the bullet did not land where he shot so that tells me it had to fly up somewhere.

there is no way that this is real. Looks like they're using one of those magnetic stirring systems they use in chemistry labs where you drop the rod in the beaker and put it on the spinning magnet plate.



I'm calling shenanigans!!!!

If some one is looking for that big vacuum for the bullet drop test I know where there's a giant vacuum available.

I don't know how they did it, but I think it's fake. Magnetic stirrers don't work on copper or lead. If the bullet was fired it wouldn't be "pristine." It would have rifling marks on it.

uh oh.... what was seen can not be un-seen.... now I have the strong urge to try this

It looks like there are rifling marks on the sides to me.

Can I watch? When do the lakes freeze in Little Elm?

[terryg]

That is so bogus. The spinning bullets aren't even 'found' in the huge impact craters ...

[Tamie]

That's was choppier than the Blair Witch video and less believable.

I just read all 9 pages of the MythBusters threads with self-proclaimed experts in physics, special effects/CGI, and firearms chiming in.

There's a lot of tit for tat, things brought up, things explained. Some highlights from the thread which I did not see any refutation of are:
The boy first posted a short video only of a bullet spinning and was told to go out and re-video using certain criteria, which he did and posted just days later (that being the video posted above).

Frame by frame analysis shows that one of the spinning bullets remains in scene 100% of the time, making tampering or editing to create an illusion in this video an extraordinarily time-consuming and expensive venture, much beyond the reach and knowledge of even those beginners in the field of special effects, much less for a teen within a couple days from request to posting. The fact that the camera is hand-held adds to the difficulty in editing in such a circumstance because of the extraordinary skill it would require to line up and merge edited scenes without any discernible signs (such as the bullet being in a slightly different place) when not using a tripod or stationary camera point is far beyond the skill and equipment levels he would be expected to have access to and mastery of.

Several others have duplicated it and posted similar results. Those who shoot regularly posted anecdotes of similar occurrences when they've shot at milk jugs full of frozen water, packed earth, and bowling pins with the fired bullets appearing intact, largely undeformed, and not having penetrated the object. None of them claim historical experiences with the spinning. One person who gives no credentials says it's nothing new to him as they shot the ice and saw spinning bullets all the time growing up.

The big issue of debate seems to be what force would allow its forward momentum to stop while the rotational momentum would continue. Based on the belief that it isn't possible, the primary objection to the video is that it must be a fake because it isn't explained by their basic physics knowledge. I didn't really read those carefully as they don't seem to verify or debunk the video, but to try to explain the science behind what was happening. I didn't see any evidence that the video itself was a fake, though there were many outright statements that people believed it was so.

The poster said that he was talking with the MythBusters staff last January, IIRC, about setting it up and testing it on the show.

Good point.

It could've been carried by an African swallow though.
Supposing two swallows carried it together.
