Remember those flat cellophane "fish" that curl up in your hand, supposedly indicating something about your destiny? I've always wondered how they worked—what caused them to curl one way or the other. In this short video from The Curiosity Show, we learn a simple lesson about cellophane. Spoiler alert: the fish can't read your mind.

If you, like me, wondered where a person would get a bit of cellophane to try this, you can buy cellophane online (lots of it!).
