UGears STEM LAB Random Generator Model Kit

A beautiful little eco-friendly wooden machine, mixing precision (in the assembly) and scientific randomness (in the answers it provides). A step-by-step manual guides young scientists through building gears, axles, internal mechanisms and understanding basic geometry. The model is composed of 160 parts and takes approximately 2 hours to complete. It's almost entirely made of wood with a metal ball and a rubber band to help power it. It's Magic 8-Ball, next level!
