Science Projects at Green Fair

Bill Kuhl

I brought my display of science toys; mousetrap cars, solar model cars, water rockets, and electric motors to a "green fair" yesterday. The turnout was disappointing but the feedback I was getting was great. One young boy told me how he had designed and built a radio control car using cheap stuff and how he has friends that like to do the same sort of things. Parents and grandparents looking for science projects for kids. Almost everyone that stopped by took a ScienceGuy.Org card.

Bill,

Thanks for showing my son your cars and rockets. This morning I built a plastic bottle pressure rocket and launcher using a bike tire tube valve and wine bottle cork for the launcher. I made the top very loose so the parachute came off every time as long as I kept it dry. It typically launched at around 30 - 35 psi. I uploaded a video of one of the launches on you tube.

So far I have an article and two videos about the water rockets, I plan to come up with a construction article of a simple water rocket article in the future, actually more construction articles, because people are asking for that now.
