Description
If you have trouble deciding what to do with your day then the Dynamometer is just the machine for you. Similar to our Pneumatic Engine, this model operates by turning air pressure into motion. Blow on the top gear to set the mechanism in motion. The air pressure you apply spins the arrow until it lands on your task for the day.
The Dynamometer is one of the simplest UGEARS models but at the same time it demonstrates several basic principles of mechanics, including the cascade of gears and the mechanical junction known as the Geneva drive.
Self-assembly; No glue required
