Make a floating pingpong ball

Friday, December 28, 2007

Using Mom's blow dryer you can create an experiment that might get the entire family hooked on science.


* Blow dryer

* Pingpong ball


* STEP 1: Plug the blow dryer into an electrical outlet, switch the setting to high cool and point the flow of air toward the ceiling.

* STEP 2: Place the pingpong ball into the flow of air.


The air pressure surrounding the stream of air is higher than the air pressure in the stream of air. The higher air pressure keeps the pingpong ball from escaping the stream of air.

While the stream of air is pushing the pingpong ball upward gravity pulls the pingpong ball downward causing your pingpong ball to float in the air.
