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
Description
It’s time to get medieval on physics! Build ten sleek and updated 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 Type of weapon based
on a bow and arrow, in which the bow is mounted horizontally on a stock. Build
and experiment with five different types of crossbows. The projectile, called
the bolt, has a safe 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 another 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.
