ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.

At the Manitoba Science Centre we built a wave tank with pneumatic (hollow
rubber) bladders, used on semi-trailer truck suspension, on either side of
the fulcrum. They inflate in alternate periods (using a clock cam) when
visitors push a button. While it was very reliable it was not terribly
interactive, and certainly not what I think you are thinking of via visitors
pushing on large rubber bladders. I have seen other tanks where visitors
move a plate, horizontally, to create a beautiful wave (possibly at
ScienceWorld B.C.), but I think this was also electrically controlled.

Subject: Ways to Power a Wave Tank
Hello,
We are developing a wave tank as part of an alternative energy exhibit and
are looking for a fun way for visitors to create waves. I've heard there's a
wave tank where visitors push against a rubber bladder. Has anyone seen
such a device, or know about its reliability?
Thank you in advance for your help!
-Eric
