Trebuchet Calculator Tool – Model your Pumpkin Launching Design for Maximum Distance

Super cool program: Trebstar, a Mac and PC trebuchet modeling software, calculates the range and efficiency of your trebuchet design.

The program has various configurable parameters and animations, and also shows the forces on the different components of the trebuchet itself – lets you know what part might break when you build your masterpiece. A handy tool for aspiring punkin chunkers! And a quick reminder: watch me on Science channel’s Punkin Chunkin special this Thanksgiving. It’s awesome.
