Keep a Candle Burning Underwater!
Magic tricks can't hold a candle to this scientific triumph! Watch your child create a bizarre candle souvenir by getting a candle to burn below water. With just the open flame above the water's surface, this process will transform the candle into a hollow tube of wax. The water surrounding the candle is the secret to this "trick." It keeps the exterior of the candle at a cool temperature, so the area touching the water never melts.
