(This should go without saying, but just in case... don't try this at home. It's dangerous and stupid. Also, you could potentially go to jail for it, without a team of lawyers and a lot of paperwork. Just save yourself the trouble, please.)World-famous magician David Blaine is well known for his astounding magic and Houdini-esque stunts. Most of these dangerous feats are well-supervised; they also require training and practice so that the risk of death is minimal. But the real magician, in our opinion, was the man firing the gun. This shot would give even a practiced marksman reason to worry. However, with nothing but a metal cup keeping the bullet from the back of your skull, it would be hard not to flinch. Either way, this one's a nail-biter.
