If you want to build a marble run, there are no limits to your creativity. You will need cardboard tubes, scissors, tape, a box, and a large surface to stick things on. Start by drawing the marble run on paper before you start building it. Then roll up your sleeves and get started. The rolls need to be cut to the right size. Make “windows” in the rolls so that you can see the marbles rolling through the run. You can simply cut out the rolls, roll up pieces of tape and stick them on the rolls. Once you have cut the cardboard tubes to the desired lengths, wrap the tape around the ends of the tubes to attach them together in the places where you want to have windows. At the end of the run, you can place a box into which the marbles will fall.
