Magicians and mentalists of all kinds love to push the boundaries of what's humanly possible. It's why Houdini straps on a straitjacket, or why David Blaine holds his breath for ten minutes. Even as impressive as some of these moments are, sometimes I can't help but ask: "Why???"

Case in point: Martin Castor is a mentalist and hypnotist who's recently found success moving up the ranks on Denmark's Got Talent. A few days ago, he posted the video above to his YouTube channel, where he asks his audience to choose the order of the numbers one, two, and three. He then displays three animal traps on a table, and proceeds to activate them with carrot sticks - the trap severs the carrot cleanly in half. And then he just... puts his hand in the last one. Just puts it in there. 

If you have the stomach for it, you can watch the whole video above. It's an incredible talent, but you'll probably clench your teeth for the entire three-minute routine. If you're looking for something a bit less... painful, be sure to check out the mesmerism routine that won Castor a golden buzzer on Denmark's Got Talent from a few months ago:
