Pneumatic Engine
Let a balloon bring engine mechanics to life
This compact wooden engine kit turns air pressure into moving pistons and gears. An inflated balloon provides the pressure, while a built in gauge adds another visible detail. It suits an inquisitive builder who enjoys practical demonstrations of how an engine transforms stored energy into motion.
