Tinkineer's Marbleocity introduces children to engineering principles and physics concepts with dynamic hands-on STEM model kits made of precision-cut wood in the USA. Each kit includes easy-to-follow assembly instructions in a graphic novel that features the Tinkineer characters. The comic introduces a physics concept or engineering mechanism that is the focal point of the model, all in a fun and engaging way! The result is an awesome kinetic sculpture and some new physics and engineering insight! Building requires only household white glue…no special tools! It's a unique and playful learning experience for beginner and experienced Makers alike!
