Has your magic 8 ball been failing you? If shaking a ball of liquid isn't giving you the answers to your most critical yes or no questions, the UGears STEM LAB Random Generator might be the problem-solving magic you've been looking for. You might have questions about how to build it, but once you've followed the step-by-step construction manual, any other simple question can be solved with the simple push of a button. Designed with smooth gears and completely random results, this 3D model helps you make your decisions by scientific randomness instead of magical randomness. Each piece is made from carefully laser-cut sustainably-sourced plywood that comes with a fresh real-wood scent. By following the included paper manual or an easy online video guide, you can have your Random Generator ready to answer your questions within about two hours. There are six possible answers including "yes," "try again," "later" and the ever-reliable "do it." There is a precise 1/6th chance that any one of these answers comes out on top thanks to the careful symmetry of an internal octahedron. The eco-friendly materials are refreshing after decades of plastic models. The model is almost entirely made of wood with just a metal ball and a rubber band to help power the drive gear. A button and clutch work with potential energy to set the mechanism spinning and a drive wheel keeps the thrust evenly distributed to avoid predictable answers. Scientific minds can also explore concepts including a three-axle gear, internal octahedron, overrunning clutch, and basic geometry.
