Eisco GP00015 Garage Physics Murlin Trebuchet Kit - Explore how the use of a simple machine (pulley) efficiently redirects gravitational potential energy to throw objects farther than a traditional trebuchet. The Multi-Radial Linear Node (MURLIN) Trebuchet is able to transfer much more energy to the projectile than the standard trebuchet. In fact, this system, with a throwing arm that is half the length as in our standard trebuchet (GP00009), is able to throw just as far, if not farther. Assembled kit throws the included ping pong ball 30 feet or more. The included guide provides clear assembly instructions with pictures. It also contains pedagogy for exploring concepts of energy transfer using the scientific method. Manufactured with high quality, precision-cut birch veneer pure bond plywood.Who knew that the trebuchet, one of the most elegant of all medieval weapons ever invented, could be improved by redirecting the pulling force of the counterweight with a pulley. |
