Kraul Wooden Cogs STEM Experiment Kit

Inspire a lifelong love of science and engineering with the Kraul Gearwheels Experiment Kit, a hands-on introduction to the fascinating world of mechanics. Designed for curious minds aged 12 and up, this wooden experiment set lets children and teens explore the principles of gears, motion, and chronometers through real, working models they build themselves.

With easy-to-follow instructions and all the tools included, from screws to wrenches, young engineers can experiment with different gear configurations and create their own working cog train. As they assemble and adjust each piece, they’ll discover how gears transfer motion, change speed, and work together to keep time.

This STEM toy combines creativity, problem-solving, and physics in action, helping children build confidence as they see theory come to life through play. It’s an exciting, hands-on way to explore mechanical engineering and develop a deeper understanding of how things work in the world around them.
