Leonardo da Vinci Kit - Catapult
Examine da Vinci's improvements to the catapult with this hands-on kit. The catapult components are molded in wood-colored, wood-grained plastic for a realistic feel. Pieces snap together, so the whole model can be constructed without having to use glue. The finished catapult stands about 5" tall and has a 9" long launching arm. The launching mechanism uses a very simple, but effective design. An instruction manual is included which also gives a lot of background on da Vinci and his work. Are there any improvements you would make?
