Easily demonstrate the unexpected effects of low air pressure.

Description

You provide the fast moving air, and we'll take care of the rest! You can easily demonstrate the unexpected effects of low air pressure with an electric leaf blower or vacuum cleaner (exhaust mode). A fast stream of air across the top of this fascinating device reduces air pressure in the tube. As a result, ambient air pressure propels the ping pong balls upward, in apparent defiance of gravity! Students at all levels will marvel! Instructions included and available online.

Poor Product Information

Feb 24, 2016

I purchased the Bernoulli Blaster to do a different experiment - the Ping Pong Ball Blast-off. You drop a ping pong ball with a golf ball below it and the collision transfers the energy to the ping pong ball. The problem is your Bernoulli Blaster uses custom ping pong balls, slightly smaller in diameter than regulation ping pong balls and therefore the tube is too small for the golf ball. It would have been nice to have the tube diameter in the product description. I have donated the Bernoulli Blaster to to my local elementary school science dept. It works as advertised, just not for the purpose I bought it for.

Owner Response: We're sorry the blaster did not work for your intended purpose.

Fun and educational

Great way to help children understand about air pressure. Took a few tries to find that sweet spot but trial and error is also a teachable moment.
