1994,1995	Designed simple exhibits and take home demos for fund raisers for the invention factory, a new science museum in Trenton, NJ. Demos included a water tank with vortex cannon, a take home vortex cannon made of a plastic container and a rubber membrane, and a tornado vortex machine made of soda bottles and rubber hose.
1996	Designed and demonstrated a four story soap film at the Carnegie Science Center in Pittsburgh, PA, on several occasions. In one case it was for the ASTC (Association of Science - Technology Centers) annual conference. In another case, CNN Science and Technology Week program.
1997	Following my web site (and with some of my e-mail advice), science centers and many others around the world built my soap film apparatus for demonstration events. The Xperiment huset of Vaxjo, Sweden, has made a permanent exhibit which is has been running continuously.
1999	The American Physical Society requested that I install and operate a 40 foot tall soap film during their centennial celebration.
1999	During the same conference, the Division of Condensed Matter Physics requested that I create a set of hands on exhibits on soft condensed matter physics.  Topics included Ferrofluids, Colloidal Crystals, the Weissenberg Effect, Wormlike micelles, and Aerogels.
2000-2001	At the request of Ann Hamilton, I built a flowing film exhibit which will be used in a modern Dance and Vocals performance by Meredith Monk and Ann Hamilton.
