Hooked on Science: Floating ghost ball

Thursday, October 27, 2011

Using a few items from around the house, you can make a ball float.


* Hair dryer

* Styrofoam ball


n STEP 1: Turn the hair dryer on and hold it so the air flow is toward the ceiling.

* STEP 2: Place the ball in the flow of air.


As the flow of air pushes the ball upward, gravity pulls the ball down making it look as if it is floating in the air.
