Penny Lab

When doing the lab, what I did was put a penny on a flat surface, and with a medicine dropper put water droplets, one by one on the penny until the surface of the penny overflowed with water. At first, I predicted that only 5-7 drops of water would go onto it without overflowing. After repeating this two times, the highest number of drops on the third time repeated was 49 drops. I learned that the slower I put the drops on it, more drops were able to fit on it.
