The question investigated in this expirement was “How many drops of water can fit on one side of a penny?” It was hypothesized that “If I take an eye dropper and drop water on pennies, then the pennies will hold as much water as possible because of the surface tension and cohesion.” The result of this expirement proved my hypothesis was correct because the pennies did hold as much water as possible until there was way too much water on the penny and the mass of the water grew greater then the penny. The answer to the purpose of this expirement is that with just regular drops of water pennies can hold an average of 30.25 drops of water. When the water is tampered with and mixed with a soapy solution the Penny does not hold as much water. In the soapy solution tests the average amount of drops the penny could hold was 13.25.
