Build a model of four-bar linkage! Use the hand crank or attach a motor (sold separately) to watch the marbles ascend and then flip-flop down again! It’s part of the first Marbleocity marble machine line to feature colorful plastic accents! Perfect for beginners; one hour build time. Triple Play models can connect to one another for bigger fun! Also works with Marbleocity Motor Kit, sold separately. For ages 9 and up.

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!
