Ugears Dynamometer

The UGears Dynamometer design is inspired by real-life mechanisms, so you can see exactly how simple machines function to transfer energy and achieve their results. With no box hiding the gears and mechanisms, every blow on the gear sets in motion a wondrous series of rotations that culminates in the spinning of the arrow which is plainly visible to be studied and enjoyed by the user. The Dynamometer is just as fun to build as to play with, so gather around with family and friends to construct your Dynamometer and share the satisfaction that comes with building your own toys. The Dynamometer is crafted from high-quality plywood boards using 48 precision-cut parts which require no adhesives or tools for construction. It can be assembled in under 2 hours with the help of the detailed instruction manual. No getting mired in messy glue or scouring the garage for the right tool, just unbox and get right to the building! Suitable for ages 14 and up.
