Congratulations on your site Balancing Ball (at http://www.exploratorium.edu/snacks/balancing_ball.html), which has been awarded a Highly Commended rating by Schoolzone's panel of 250 expert teachers. It is included in our searchable database of educational web sites.
This is what we say about it:
"Bernoulli effect using a hair dryer and a ping-pong ball. Pupils can feel the ball be 'sucked' back into the stream - which goes to show that there is no such thing as a 'suck' only a change in air pressure causing a push."
Keywords, for search purposes:
"Physics Bernoulli Effect Fluid Dynamics Air Pressure Speed Forces".
