Archimedes would be proud
For a school project, my 11 year old is taking on, for the night, the persona of Archimedes. Part of the project was coming up with three artifacts related to his character, so last weekend we built this catapult.
It's modeled after a picture we found on the internet. Built from 1/2 inch square pine, with a white oak bow and bamboo axels.
Of course, it being Easter last Sunday we tested the beast on the most available item, and discovered it will shoot a jelly bean 30 feet.
