You may not realise it, but your kitchen is one of the most well-stocked chemistry sets you could ever hope for. And it's not only for creating edible chemical reactions. NASA might rely on giant laboratories and factories to build its rocket engines, but all you need is a piece of pasta, a jar, some hydrogen peroxide, and a little yeast. Oh, and fire.
As long as you're not expecting to a put a human into orbit, this simple experiment will produce a surprisingly satisfying rocket engine on a very small scale. Mixing the hydrogen peroxide and yeast produces a steady flow of oxygen, and the pasta works well as makeshift rocket fuel. And while your creation won't produce much thrust, it still produces a decent flame, so be careful with this one, OK?
