Hydraulic Gearbot

Catapults have traditionally been powered by using the energy in twisted rope - as in ancient Greek and Medieval Times- or in bent wood - as Leonardo da Vinci designed in his Renaissance era catapult. Pathfinders has now designed the very first hydraulic catapult - a HYDRAPULT! - using the energy of moving fluid to hurl items. 

 

Designed to get both boys and girls into learning about levers and simple machines, trajectories, fluid power and engineering, this newest kit has three different throwing machines in one, and nothing gets kids more excited about learning than hurling things!
