Thames & Kosmos Catapults & Crossbows Science Experiment & Building Kit | 10 Models of Crossbows, Catapults & Trebuchets | Explore Lessons In Force, Energy & Motion using Safe, Foam-Tipped Projectiles

It’s time to get medieval on physics! Build ten sleek and up to date models of catapults and crossbows. These classic siege weapons from the middle ages also happen to be great tools for teaching physics, including lessons in force, energy, motion, and projectiles. A crossbow is a medieval Form of weapon according to a bow and arrow, wherein the bow is mounted horizontally on a stock. Build and experiment with five several types of crossbows. The projectile, referred to as the bolt, has a secure foam tip and a special cross-section that prevents other projectiles from being launched. When the bolt is loaded into the crossbow, a rubber band is pulled backward and energy is Stored in the stretched Rubber band. A trigger releases the bolt and the rubber band launches it through the air toward its target. A catapult is any other medieval ballistic device that uses mechanical rubber Bands and counterweights to fling projectiles into the air. The 32-page, full-color manual has illustrated step by step instructions.
