I received a "build-your-own" medieval trebuchet kit from my Secret Santa. It was a little intimidating at first because there were a lot of parts and instructions, and I would always just build random stuff with my LEGOs instead of the actual kits, but once we got down to it, it was an awesome fun Christmas Eve activity to build the trebuchet. It has a lot of kick to it and can launch a walnut 10+ meters easy! Some calibrations will be required before test firing flaming cherry bombs can begin. Very cool.
