We love this marble machine made out of a cereal box that we spotted at Made By Joel. He has a great tutorial on how to make it! For ours, we cut out multiple holes in the lowest ramp and positioned it at an upward angle—we wanted to see if we could make the marble could fall into the second or third hole instead of the first.

Getting the marble in the second hole was not too hard, but we still haven’t been able to get it in the third hole!
