Re: Need help with 7th Grade Science Fair Project
There are a bunch of really simple but very cool experiments you could do to explore the Coanda effect. This is the effect that enables airplanes to fly (**not** the Bernoulli effect). For example, running water off the surface of a spoon, blowing air across the surface of curved pieces of paper, that kind of thing. I'm sure Google will be your friend here. These experiments will be pretty simple, give you results that are not trivial, and also have a good chance at educating your judges (who may have the incorrect standard view of a lot of these things) which will definitely allow you to score well.

Re: Need help with 7th Grade Science Fair Project
forget the trebuchets - build one of these.
