How to make a paper towel marble run.
We have seen this idea around and thought we should give it a try. We chose a rainbow theme.
First get a bunch of empty paper towel tubes. (These are cleaner than using toilet paper tubes.)
You can cut them to any size. If you cut a notch (to make a landing area) out of the paper towel tube, then the marble will fall from one tube to the other more easily.
Then get your paints out and paint and create! We have seen paint, colored tape, stickers and more. Your imagination is your only limitation here!
Use hot glue to add some magnets on the backs of the tubes and you are done!
TIP ALERT! Do NOT put a ton of glue on the magnets because the tube will be so heavy that it won't stay on the fridge.
