One wet penny buys a lot of science fun

How many drops of water will fit on a penny without running off? Challenge your elementary schooler to find out. First, ask your child to make a prediction. Then, give your child a penny, a glass of water and an eyedropper (a straw will work if you don't have an eyedropper). If your student works slowly it's possible to get as many as 24 drops on the penny. Repeat the experiment. Does your child get the same number?
