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 Pendulum is a stylised educational model, an interactive study guide to the mechanism, only for learning its essentials and principles of working. The pendulum is one of the basic and most reliable time measuring mechanisms. Its working principle is based on the model\'s constant amplitude oscillation under the force of gravity (weight) and potential energy (tension force) of the rubber band. UGears 70133
