    I love these Science Fair things[​IMG]
    We need to "invent" a simple machine using at least one of these: Lever, Pulley or Inclined Plane. The product must be useful and make a job easier. Size does not matter.
    Anyone care to contribute any ideas? Or links.

    How about a lever that can safely pry DVDs from any type of spindle? I'd buy that for a dollar!

    Not a lot of takers here. I would think at least Jack would have a suggestion for how to lever your 3rd grader into a star child. [​IMG] I personally try to block out the Science project days...not that I don't believe in them...but it often becomes the parents 'job'.
    Also sometimes when a child has a 'good' idea to follow. The 'rules' do not permit.
    One we did in a timecrunch panic, 2 hermit crabs set on an obstacle course to race with predictions and results. It won a first...only because my son grudgingly documented that the 'results' were contrary to what he had predicted for the outcome. I had to do some fast talking on that one...he wanted to manipulate the results till he 'got' his predication. I had trouble explaining to him the the whole point of 'experimentation' was to set up a trial run and document regardless result...then explain where you went wrong and what affected your predicted expectations.
    The other was when we were driving along a few weeks out from science fair deadline, with no choice settled. And my son asked. 'Mom, why can birds sit on power lines but people can't touch them?". I said bingo! Thats your 'project' - to find out 'why'. He went to district with that one.
    I asked,...he was in a hurry but suggested something using a lever/pulley/or plane to facilitate 'cleaning your room'...might have been on his mind since he has to do his. [​IMG]

    Thanks for the replies. We've narrowed it down to a couple of ideas, still working on it though.
    Bob, if I could invent that I would make a million here at the HTF alone! Hmm....
    Mary, I can't wait to "block out" these days[​IMG]

    No specifics here, but you might consider a catapult or trebuchet. Since there is no size restriction, you could set it up in the parking lot and throw maybe a 500 lb rock into the principal's offi.....

    Well, maybe that's going a bit too far.

    Good luck with the project!!
