Keva Contraptions Trebuchet Building Set
Keva's Contraption Trebuchet lets kids build a working replica of a medieval siege engine. Pre-drilled planks, included wood glue and step by step instructions make assembly quick and easy. Once the Trebuchet is assembled kids can make adjustments by changing projectiles, putting more weight in the counterweight basket. Which adjustments make the included ball fly further? Ages 7 and Up. Winner of the Parent's Choice Gold Award.
