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.

Why do ping pong balls float?
If they float in water, then it is because the density of a ping pong ball is lighter than the density of water. The density of water is just below 1, and the density of a ping pong ball is much less than 1.

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 minimum number of ping pong balls needed to get a steel cube to float?
The number of ping pong balls needed to get a steel cube to float would depend on the mass of the steel cube.
Why does a ping pong ball float?
It is lighter than water and is hollow with air.
Which floats a baseball or a ping pong ball?
This depends upon what liquid you are placing the baseball in to. When the volume of liquid displaced by putting the object into it is less than the weight of whatever you put in, it will float. So, if a baseball weighs 300g and it is in water, and it displaces 400g of water (because of the baseballs volume), then it will float.
What are some songs about ping pong?
Among the only songs "about Ping Pong" are a 2007 Enrique Iglesias song called "Do You Know (The Ping Pong Song)." While not referring directly to the jargon of the game, the track has a sample of a ping pong ball bouncing in a steady rhythm throughout. The Raffi song "Bananaphone" also has a lyric "Ping-pong ping-pong, ping-pong, ping."
