Introduction: How to Make a Dancing Penny
A science experiment for all ages. Keep the kids busy over the holiday. This demonstration will entertain them for hours. You can have fun making one for each of the kids in your family. All you need is a penny and a bottle. Wet the top and place a penny on top. The heat from your hand causes the air pressure inside to increase until the penny pops up slightly. It continues for a few minutes.
