Wood, gasoline and food are examples of potential energy. Something moving has kinetic energy. A rolling ball or falling rock has kinetic energy. Hang the spirals from thread over heat sources, away from drafts. Heat sources could be light bulbs or radiators.
Water Fountains Cut off the top of a plastic soda bottle.
Place the bottle in a pan to catch the water. Cover the holes with your fingers and fill the bottle with water. Move your fingers.
