UGears STEM LAB 160 pcs Random Generator

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.

Careful physics has gone into the design of each Random Generator. Each piece is made from carefully laser-cut sustainably-sourced plywood that comes with a fresh real-wood scent. Pop out the pieces and gently sand or wax interlocking parts to get just the right fit in case of small deviations. 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. It comes with 160 parts and is recommended for anyone age eight and up, though younger children might enjoy working on this project with a bit of adult assistance.

There are a number of scientific elements in this model, making a great science fair project or activity for brainy young scientists and older explorers. The mechanism includes ways to explore weight and balance with an internal metal ball that drives the random chances. 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. Although not every kid is as excited about STEM projects, giving your young ones some base examples is a great way to expand growing minds to the possible applications of math and science in real-world situations.

Even though this kit is an ideal IQ game for kids and teens, anyone can enjoy the simple pleasure of solving these simple puzzles and physics experiments. UGears is always available to help out in case of lost or broken pieces, ensuring that your project is enjoyable and beautiful even if it takes some time to come together.
