Sword-Swallower Under The Glow of X-ray

Some people think of sword swallowing as a magic trick. After all, as with most magic tricks, sword swallowing doesn't seem like something that should be possible. It can be a little easier to accept the idea that it's all an illusion than to believe that a person can guide a long piece of metal all the way into his stomach. If you've ever watched a sword-swallowing performance, you may have also gotten the impression that the performer is trying to gain the audience's trust, just like a magician does. He might invite members of the audience to join him on stage to inspect the swords or even to pull them from his mouth.
