Make your own battery using copper coins, vinegar, foil and cardboard. I had enough energy to power an LED with mine and also a TV remote! Really simple science project and easy to do yourself.
Make your own candle from a stick of butter and some toilet paper MacGyver style.
Most people wouldn’t think of butter as a flammable substance, but in this project they are! We’re making emergency candles that burn for hours .. using some toilet paper, and a bit of butter!
