Fischertechnik pneumatic power

The inexpensive pneumatic excavator toy Pneumatic Power playfully teaches the basics of pneumatics and uses realistic models to show how pneumatic valves and cylinders work. The air is manually pumped into an air reservoir. By actuating the hand valves, the compressed air reaches the pneumatic cylinders via the hoses. In addition to an excavator, four other models can be built. The didactic accompanying information on the subject of pneumatics is available online for the young inventors.
