Eisco™ Garage Physics Large Trebuchet DIY Kit

Description

• Medieval weapons, engineering, and physics - not a bad way to spend a Saturday afternoon constructing this trebuchet which will throw the included ping pong ball more than 30 feet and heavier objects farther
• The main material is high-quality precision-cut Birch vernier pure bond plywood
• All necessary parts are included and holes are pre-drilled
• The kit is specially designed to be safe and robust
• Dry firings and heavy projectiles are no problems for this kit
• All that is needed for assembly is time, a screwdriver, a hammer, and fun
• No glue, mess or fuss, just assembly, and experimentation The trebuchet is one of the most elegant of all medieval weapons ever invented
• With a simple counterweight, beam arm, and sling, heavier projectiles can be launched much further than is possible with other siege engines
• Think of it as a machine which transforms gravitational potential energy into kinetic energy
• A lot of kinetic energy! Arcing across your yard! We include a ping pong ball, but have experimented with marshmallows, jelly beans, bouncy balls and other safe objects
• Two release pin angles allow exploration of how the release angle changes the trajectory
• The included guide provides clear assembly instructions with pictures
• It also contains pedagogy for exploring concepts of energy transfer using the scientific method.
