Can you make the ball float? This "magic" trick is really a basic lesson in air pressure.
It takes a little practice, but children as young a three can master it, and everyone has fun trying.
This clever little item demonstrates Bernoulli's Principle – Law of Pressure Differential. As air is forced around the ball it must move faster in order to "catch up" to the other side. The result is a decrease in air pressure around the ball that in turn keeps the ball in place.
