You can scare the hell out of your friends with the neat trick, or you can use it in your next horror-filled independent movie, to scare the hell out of your viewers. Watch this prank video tutorial to learn how to embed floss into your neck.
This could be considered a magic trick, but it's more of a prank or special effect. It creates the illusion, that when you rub dental floss around your neck (like you're cutting yourself), it gets stuck in your neck, like slashing your throat type stuff. It's a really cool gag and effect.
