Leonardo da Vinci Catapult Kit

Catapults were first invented in Ancient Greek and Roman times, however our common idea of them is based on drawings we have from the Medieval Ages. Leonardo redesigned the catapult around 1485, and used the springlike energy stored in bent wood to give power to the swing arm.
