Why does a ping pong float with a hair dryer?
When you point a running hair dryer upward, and place a ping pong ball in the air stream, it will eventually float somewhere above the hair dryer and near the air stream. It stays above the dryer because the drag of the air balances out the ball's 2.7 grams of mass, and near the air stream due to the Bernoulli effect. The Bernoulli effect is the drop in pressure when a fluid's velocity increases; you can demonstrate it by blowing over the top of a piece of paper. It is partly responsible for the lift generated by an airplane's wing. The ball is drawn towards the center of the air stream due to the increasing velocity and the resulting Bernoulli force, but is pushed away by the air glancing off its surface. The ball maintains a position where these forces balance out, perhaps wobbling back and forth so the average forces balance out.
When was the hair dryer invented?

How do you demonstrate Bernoulli's priciple with two ping-pong balls?
You can demonstrate Bernoulli's principle using a hair dryer and one or two Ping-Pong balls. Simply turn on the hair dryer and point it upwards. Then place the Ping-Pong ball in the air stream so it the upward force of the hair dryer balances the force of gravity. The ball will appear to levitate. This demonstrates the Bernoulli principle that fast moving fluids are at a lower pressure than slow moving fluids. Air from the hair dryer is at a lower pressure than the outside air. So a ball that is smaller than the air stream can be balanced in it.

What is the usefull and wasted energy in a hair dryer?
Useful energy in a hair dryer is the electrical energy converted into heat to dry hair. Wasted energy in a hair dryer is the heat that is lost to the surroundings instead of being used for drying the hair.
