UGEARS Pneumatic Engine 81 Piece Wooden 3D Puzzle

The UGEARS Pneumatic Engine may be small, but is definitely mighty, giving a sneak peak inside a functioning steam engine. The model Pneumatic Engine comes to life by either having the user blow into a special socket, or by using an ordinary air balloon. All the parts move as if they were inside a real steam engine, the amazing thing is its built entirely out of plywood! The Pneumatic Engine comes with its own, built in air pressure tachometer, and two small compartments for storing spare parts.
