In the last two weeks of September, I made a marble run. A marble run is like a rollercoaster but for marbles. The run I made has three tracks and is powered by an XL motor. It is five feet six inches tall and made of Lego Technic. I made it so it could break down into smaller pieces so I could bring it to church to show my friends. I made a video so you could see how it works.
