What is it about marble runs that makes them so compelling? Kids (and adults!) can watch marbles going down a track, passing through various obstacles, for hours on end.  Marble runs are fascinating, they grab our attention, and yet they're also relaxing. Marble runs and races have become an unexpected YouTube phenomenon, with thousands of videos racking up millions of views. You choose a marble to watch, to cheer for, you wonder which path it will take, you put yourself in the marble's place, imagining that you are right there with the glass ball, going on a marvelous, unknown journey, with twists and turns and surprises around every corner. The thrill is even greater when you've built the marble run yourself. Now you're not just passively watching a video, you're fully invested because you built a wondrous machine with your own hands.

Presenting the Ugears Marble Run Chain Hoist—an exciting combination of art and engineering. The Marble Run Chain Hoist is modular, and can be connected to other Marble Run Chain Hoists (2 or 4 models can be connected, in pairs) using special connectors (included). Attach two Marble Run Chain Hoists together frontally, or connect four together, both frontally and laterally, for a mini system of hoists and runs.

Experience the satisfaction of building your own intriguing, 3D puzzle/kinetic sculpture/marble run with your own hands As you build this ingenious wooden marble run, you will learn about the action and interplay of drive gears and driven gears in gear sets, the delicate action of counterweights, and be intrigued by the mechanics of the 3-way switch and accumulator as they determine the marbles' course.

The fun doesn't stop with the build. With static models the completed model often gets put on a high shelf collecting dust. Not so with Ugears! Once you finish building this DIY marble run the fun is just beginning! Watch the wooden puzzle come to life as you crank the hoist to send the marbles on their adventures. For anyone looking for a toy that will give more than 5 minutes of fun, a marble run is certain to capture the attention of any child (or adult!).

Let the good times roll!
