In this activity each player will drop pennies one by one into a full glass of water. Be sure to count your pennies as you drop them in! As the pennies go in the surface tension becomes more and more evident. Once the water spills you have completed the round. Make sure your glass is on a smooth even surface. Be sure to have a pitcher or extra glass of water to refill the cup for the next player. It is also a good idea to have a large bowl to dump your glass to get the pennies out and restart. Dry pennies may be easier to work with as well so be sure to have a towel handy.

You can try it again using different water temperatures and seeing if there is any change. You can also try using different objects like paperclips or larger coins.
