Nathan found this idea in a back issue of Highlights magazine and I finally gathered the supplies to put it together. We hot glued different cardboard tubes to the inside of a box lid, then made a start and finish out of other random containers. Put the marble in one end and tilt and twist to get it to the other end! Ours isn’t pretty and painted nicely like the one in the magazine, but it came together quickly and has been played with many times since we made it. Fun!
