Incorporated, a worldwide network of science museums and related institutions.

Hi all--
Somewhere, long ago, one of our wonderful volunteers saw a neat exhibit
where a small diameter pipe is connected near the bottom of a large
diameter pipe. A bowling ball drops down the large pipe, compressing
the air inside it; this causes the tennis ball resting on the smaller
diameter tube to shoot way up in the air. He'd like to build one for
our outdoor Science Park area.
Our early experiments have not been very successful. Any hints or
suggestions as to someone who has done this successfully would be most
appreciated!
