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.

This old-timey truck sure is pretty to look at, but it\'s not just for show. The Ugears Pickup Lumberjack is a working truck with a job to do, and that\'s hauling wood (or hay bales, or work tools—whatever you can imagine)! Based on the popular 1959 Chevrolet 3100, the DIY wooden model features a 1m x 7mm spring motor (same as the powerful Ugears Drift Cobra) allowing the Pickup to travel up to 6 meters and haul loads of 400 - 450 g in the truck bed. The winding knob is stylized to resemble a custom open top air filter emerging from the hood. Lift the hood to reveal the beautiful V8 engine firing away! UGears 70171
