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.
What are some innovative ways to store and organize a hair dryer with a hair dryer mount?
Some innovative ways to store and organize a hair dryer with a hair dryer mount include using a wall-mounted hair dryer holder, a magnetic hair dryer holder, or a hair dryer caddy that can be attached to a cabinet or drawer. These options help keep the hair dryer easily accessible and out of the way when not in use.

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.
How do you put mousse in your hair?
Wet your hair and towel dry it. Put a golf ball-size lump of mousse in your hand and rub it into your hair. Then use a blow dryer to help style it.

How many watts does a hair-dryer use?
It depends on the model, if the hair dryer is a 1500 watt hair dryer, then it uses 1500 watts on high heat. If the hair dryer is a 2000 watt hair dryer, then it uses 2000 watts on high heat. Hair dryers come in all different size wattage, so it depends on the size wattage of the dryer. Most hair dryers are 1500 watts.
Can you use a blow dryer to straighten hair that is already dry?
Its really easy to straighten your hair with a hair-dryer. To straighten your hair using a hair-dryer you need to comb/brush your hair then get a hair-dryer and put the heat level on high for about 20 seconds whilst combing/brushing. Then turn the hair-dryer off and just your hair will be straight. It may be frizzy but for this you can use hairspray to flatten.
