Learn a great deal about surface tension from this simple experiment. fill a glass full to the brim with colored water. now take a coin and gently drop it vertically into the glass. keep adding more coins. you will be surprised at the number of coins a glass of water can still swallow. after dropping the coins the water surface will bulge but its skin will still remain intact because of surface tension.
