Last week in Kitchen Science we did the flying ping pong ball experiment. It's super easy and you can try this at home. You will need a hair dryer, some ping pong balls, and a balloon.

And here'sw what you do:

1. Turn tha hair dryer to Cool and turn it on
2. Aim the hair dryer straighr up and place the ping pong ball directly over the hair dryer. The ball will floqt in the air, without falling down.
3. You can add a second ping pong ball, they will both flow above the air stream, revolving aroubnd each other!
4. You can add a balloon and it'll flow aboove the ball, without falling down!

... and here is the science behind it!

The ping-pong ball will fly up with the air from the hair dryer until it reaches a point of balance - this is where the force of gravity (which pushes the ping-pong ball down) is equal to the force of the air (which is pushing the ping-pong ball up).
The ping-pong ball stays within the column of air coming from the hair dryer because of air pressure

Look how easy it is, and how much fun!
