About This

• Build six sleek, functional toy models of catapults, trebuchets, and launchers.
• Models include classic seige devices from medieval times: crossbow, reverse-draw crossbow, onager, catapult, trebuchet, and ballista.
• The 32-page, full-color illustrated manual includes detailed assembly instructions as well as experiments that demonstrate physics and engineering topics like force, energy, motion, and trajectory.
• Specially designed and tested for safety, the kit includes soft foam balls and foam-tipped projectiles; building components are designed to allow only the included projectiles to be inserted.
• Bonus activities! Also includes cardboard target blocks to test your aim, and the box itself transforms into a castle kids can color and decorate to set the scene for their medieval physics adventures!
