UGears Dynometer Wooden Model

Our UGEARS Dynamometer uses the same principles as the Pneumatic Engine, but has a game element incorporated into it's design. In order to make the system come to life, all you have to do is blow on the top gear! Dependant on the amount of air pressure you add to the system, the arrow will spin and land on any of the eight pictures. Unsure of what to do at home? Let the Dynamometer decide for you! This is one of our simplest models to build, so a great set for a beginner it demonstrates the intricacy of mechanics, putting emphasis on it's Geneva Driver, whilst also providing a fun game once the build is done.
