In this science experiment, you will boil a leaf in 50-100ml ethanol for 3-5 minutes. The chlorophyll will be removed and will be in solution. Turn off all of the lights and have the kids crowd around. Shine a white light on the test tube of chlorphyll. The light will excite the electrons and they will emit energy in red light. It looks really cool.
