Here are just a few ideas for making marble runs using toilet paper tubes. You can put them up in all kinds of ways and places. Use masking or painters tape when applying to walls or doors so you don't peel off paint! Can you make two tracks that funnel into one? Make your marble jump an open space and then continue on the track? What happens when you use a small ball instead of a marble? How long can you make it? Grab someone in your family and start engineering!
