Leonardo da Vinci’s Trebuchet is not as well known as his other siege engines, but is an interesting design as it has a single supporting mast. This working model has a counterweight and swing arm with a sling that launches a small ball over 2 meters!

-Easy to make in about 30 minutes
-MDF wood pre-cut and ready to assemble(some glue needed)
-Great STEM kit to learn about levers and simple machines, combined with history and launching things- awesome!
