penny lab

Procedure: place a penny on some paper and drop water drops onto of the penny and see how many the penny can hold

Prediction: the water will over flow with three drops

Outcome: the water over flowed on twenty drops on the penny

Explanation: the positive hydrogen ends of one water molecule attract the negative oxygen ends of nearby water molecules. as a result, the water molecules tend to stick together.
