Keep the ball in the air by directing the airstream from under it. Watch the ball move with the fan, floating in mid-air at the center of the airstream where the pressure is lowest - in keeping with Bernoulli's Law.
Scientific Principle: Bernouli's Law in fluid dynamics - an increase in the speed of flow occurs simultaneously with a decrease in pressure.
