MURLIN Trebuchet - DIY Kit - Explore Projectile Motion, Gravitational Potential Energy, Velocity, Motion & Stability - Garage Physics by Eisco

The Eisco Garage Physics line is aimed at students interested in STEM concepts included physics and engineering. Each kit engages learners to discover new ideas about the physical world through assembly and play.
Step aside standard trebuchet! The MultiRadius Linear-Node (MURLIN) Trebuchet combines the throwing advantage of the standard trebuchet with a highly efficient spinning windup. The result? Projectiles launch much farther compared to the size of the trebuchet. This MURLIN trebuchet throws the included ping pong ball more than 30 feet. The throwing arm in this model is half that of our Large Trebuchet (GP0009), but throws just as far. Explore how the use of a simple machine (a pulley) efficiently redirects gravitational potential energy to achieve this amazing result. A small Phillips screwdriver is required for assembly. Kit includes instructors manual.
Wooden components made with precision-cut Birch verner pure bond plywood. Kit includes 2 A-frame supports, front and back base struts, pulley mount, swing arm, two 3/8 diameter 8 long dowels, release pin, leather pouch, sliding pouch holder, 1 kg counterweight, pulley, 2 wood screws (for pulley), 2 orange strings (one 26 length, one 19 length) for sling, one 40 pink string for counterweight, 1 ping pong ball, and 1 rubber band, cardboard storage box and instructions for assembly and experimental activities.
