The Slow Mo Guys were inspired by an imaginary digital image of a tennis racket slicing up Jello (or jelly, as Brits call it). They had to try it in real life, and capture it in 2500 frames per second.
They made five balls of Jell-o, red, green, blue, orange, and more red, because they figured they would mess up the first ones. But they all were quite photogenic! -via Boing Boing
