Neck Cracker Gimmick/Magic Trick
A fun prank/magic trick to weird people out .. it sounds like a neck cracking!
You can move your neck at the same time as this for full effect. It's cooler than it sounds, trust us.
You could also use it for a leg break/arm break, but the neck seems to be the easiest and best way to get people to buy in. Of course, their belief only lasts for a few seconds, but it *is* there most of the time. At the very least, people are quizzical.
For $3 bucks, it's a nice investment for any prankster or someone who likes to spread smiles. My son used this at school and freaked people out in his gym class and art class. His teachers loved it and his art teacher ended up buying one. It's nice to have in your bag of tricks :)
