How to bounce a tennis ball higher than a house
Education • Science
Be sure to try this science experiment outside! It will save you the work of cleaning up the pieces of broken lamps and shattered windows.For this experiment you will need:a basketball or soccer ball a tennis ball duct or masking tape a flat, hard surface outside.Hold the basket ball about shoulder high in one hand and the tennis ball at the same height with the other. Drop both at the same time. If both are fairly new and fully inflated, they should bounce about the same height. OK, nothing strange about that. Next, use the tape to make a round, raised collar on the basketball. This is going to help you balance the tennis ball on top of the basketball. It does not have to be fancy. Just a ridge of tape in a circle that will fit the bottom of the tennis ball. Hold the basketball out at the same height as before, with the tape ring at the top. Place the tennis ball into the tape ring. It should balance there. Now, before you drop it, think about what you expect to happen. Then drop the balls. This video was made by Robert Krampf!
