This construction set will help children to learn the principles of pneumatics and uses realistic models to demonstrate how compressors, cylinders and pneumatic valves work. The new, powerful and compact compressor guarantees a reliable supply of compressed air to the models. In addition to vehicles such as hay bale pickers and tree trunk grips, front loaders, and other educational models provide young inventors with background knowledge on the subject of pneumatics in combination with the instructional activity booklet.
