What happens if air is blown in between the two ping pong balls?

Air pressure can decrease when air is in motion. When you blow air between the ping pong balls in Step 5, you cause the air between the ping pong balls to move faster, lowering the air pressure between them. According to Bernoulli’s principle, the faster the fluid moves, the less pressure the fluid exerts.

Why does a ping pong ball float in air?

This is due to gravity. Gravity is a force that pulls objects toward each other. The ball “floats” in the air at an even point when the force of gravity (which is forcing the ping pong ball down) is equal to the force of the air stream from the hair dryer (which is pushing the ping pong ball up).
