Step into the medieval era and explore physics in a fun way! Build ten modernized models of catapults and crossbows, classic siege weapons from the Middle Ages that are also excellent for teaching physics concepts like force, energy, motion, and projectiles. A crossbow, a medieval bow - arrow - based weapon with the bow horizontally mounted on a stock, allows you to build and experiment with five different types. The bolt, with a safe foam tip and a special cross - section, ensures only it can be launched. Load the bolt, pull back the rubber band to store energy, and then use the trigger to send it flying towards the target. A catapult, another medieval ballistic device, uses mechanical rubber bands and counterweights to fling projectiles. The 32 - page, full - color manual provides illustrated step - by - step instructions. Suitable for ages 8 and above.
Using the catapults and crossbows is easy. First, for the crossbow, load the bolt with the safe foam tip. Then, pull back the rubber band to store energy. When you're ready, press the trigger to launch the bolt at your target. For the catapult, adjust the mechanical rubber bands and counterweights according to how far you want to fling the projectile. The 32 - page manual will guide you through building each model step - by - step. Remember, these are designed for use with the provided projectiles only. The special cross - section of the bolt ensures no other objects can be launched, keeping you safe. After use, store the catapults and crossbows in a dry place to prevent damage to the rubber bands and other parts. Check the parts regularly for any signs of wear and tear. Have fun exploring the world of medieval weapons and physics!
