Observing Water Properties

My partner and I did a penny and water experiment. We took 2 pennies, laid them on a flat surface, and with water droplets dropped water on to them to see how many drops the penny could hold. I thought the penny would only be able to hold 4 water droplets. But I was wrong, the penny held 12 droplets in all. The height really effects how many droplets the penny could hold because the higher the droplet was held. The faster the water would fall. Plus I didn't have a lot of control on where putting the water on the penny at a greater height. Unlike when the droplet was about maybe a 1/2 inch above the penny. I could control where the drop landed on the penny and how fast it landed.
