Hey, Erich, check out recipe 83 in the Exploratorium Cookbook II for
one version of the Bernoulli blower. Dupage Children's outside
Chicago has another version where kids make their own Bernoulli
blowers with PVC pipe, ping pong balls, and a table with multiple
ports to plug into for pressurized air. It's much more open-ended
than the original and gives kids a chance to play with a variety of
configurations.
