Jumping coin experiment
Science experiments are fun to do and a great way for children to learn. Children will enjoy watching a coin jump in this science experiment and will want to do it over and over again.
What you need:
- Cold water
- Glass bottle
Number of players:
Fill a bowl with cold water.
Place the bottle neck and coin into the bowl of water to chill them.
Place the coin on the top of the bottle.
Wrap your hands around the bottle and wait for several seconds.
When you hold the bottle with your hands, the air inside the bottle heats up. The warm air pushes harder than the cool air that is outside the bottle so it forces the coin up so that it appears to jump.
