Usually I am fortunate to work with clients who understand my more zany ideas, confident from my previous successes that the new ones, yet untested, will work. Sometimes though I have to prove it first!
This catapult is an example of just such an idea. I have designed it to be built from a single sheet of plywood and standard parts from any builders or large DIY shop.
I reckon it will throw a load equal to half a brick about 150 metres or more. Right now the main parts are marked out in permanent pen on a sheet of ply leaning against my house, awaiting a chance to saw them out and assemble the thing for testing! My hope is that when I have proved that it is economical, easy to build, effective and safe (How can an 11 foot catapult be officially safe?) then clients will let me run it with a whole year group as a day building or week long learning project..
Some say if you build it they will come, with an 11 foot catapult, you build it and they run!
