Garage Physics Large Trebuchet DIY Kit, Each

Details:

The Eisco Garage Physics line is designed for students interested in STEM concepts, including physics and engineering. Each kit encourages learners to discover new ideas about the physical world through assembly and play. This trebuchet kit offers a fun way to spend a Saturday afternoon, constructing a medieval weapon that can throw the included ping pong ball over 30 feet and heavier objects even farther. The trebuchet is one of the most elegant medieval weapons ever invented, featuring a simple counterweight, beam arm, and sling that enables the launching of heavier projectiles much farther than possible with more complicated siege engines. The key to this success lies in the efficiency with which the gravitational potential energy of the counterweight can be converted into kinetic energy of the projectile. This kit explores simple concepts of energy transformation with thrilling results. The kit includes a base plate, two A-frame supports, four wheels, a beam arm, a 3/8" diameter dowel, a release pin, a leather pouch, string, a 1 kg counterweight, a counterweight pin, four wooden pins (for wheels), four wood screws (for supports), one ping pong ball, a cardboard storage box, and instructions for assembly and experimental activities.
