Make a Rocket Engine with Pasta

It sounds crazy, but you can build a hybrid rocket engine with yeast, hydrogen peroxide, a jar, fire, and – last but not least – a piece of uncooked pasta.

When the yeast mixes with the hydrogen peroxide, they react to create pure oxygen gas. If this pure gas is then funneled through a burning tube of pasta, you’ve got yourself a rocket flame!
