Penny Surface Tension

Penny Picture From
This experiment is designed to tet how many drops of water can be dropped onto a penny without the water falling off the penny. I predicted that 6 drops from a water dropper would be all. What actually happened was it held 32 drops of water before it overflowed. I think it took so much water to overload the penny because of surface tension, or water "sticking" together because it is polar.
