    Help with Science Project, please!!

    I was wondering whether anyone here could help me with a science project I have. The assignment requires me to build a catapult/launcher that can launch a ping-pong ball up to a distance of 10 metres. I was wondering whether anyone here knows of any good websites that has instructions and plans on how to make one, or if any of you have any plans or anything, it would be very helpful.

    hmm, you could try a sort of trebuchet, an old catapult that used a counter-weight to throw the object pretty dam far.

    just look for 'trebuchet' or something along those lines in google or any search engine.
