-First, we put pennies on paper towels. Then we took droppers and put one drop of water at a time on the top of the penny. We saw how many drops of water we could drop on the penny before it poured off of the penny. We dropped the water at different heights and speeds to see what worked best.
-My prediction was that the higher you drop the water from and the slower you do it, the more water drops you can fit on the penny before it flows off. Also, I tried to get my penny flat on my desk so that the water didn't have a slope to trickle down.
-It turned out that the closer to the penny that I dropped the water from and the slower I did it, the more drops i got to stay on the penny. The max number of drops that I got to stay on the penny was 24.
- I think that the water eventually falls off, because the water molecules have to keep expanding in order to connect to each other, and the surface tension decreases as the water droplets increase.
