STEM Build Catapults Kit Learn physics using medieval-era technology! Six updated models of catapults, crossbows, and other medieval launchers with soft arrows and foam balls to build. These classic siege weapons from the Middle Ages are also great tools for teaching physics, including lessons about force, energy, and motion. A catapult is a medieval ballistic device that uses mechanical rubber bands and counterweights to launch projectiles—in this case, foam balls—into the air. The 32-page, full-color manual has step-by-step, illustrated instructions for building the models and conducting experiments. Bonus: It also includes folding cardboard blocks so you can build a fake castle wall that will then be knocked down. The durable plastic pieces can be reconfigured in a variety of ways; build models from the manual or create your own models, learning about mechanical physics with simple experiments. The kit contains 88 pieces, 6 experiments, and an instruction manual. Recommended age: +8 years. Made of plastic, rubber, polystyrene. According to EN71&ASTM regulations. WARNING: Not recommended for children under 3 years, contains small parts. Adult supervision is recommended during play. Read the instructions before use, follow them and keep them for reference.
