My daughter has been faithfully helping me save the paper towel rolls for probably the last year. We were going to use them to make a cardboard castle but somewhere along the way lost our motivation (okay maybe it was just me . . . ). But when I saw this I knew just what to do with all those paper towel tubes.
Make a marble run.
We gathered some paper towel tubes, some scissors and magnets.
I cut widows into the tubes while my daughter stayed busy decorating them.
Apply some magnetic strips . . .
And you're ready to set up your marble run and have some fun. Arrange the tubes on your refrigerator doors and experiment to see which arrangement works best. The lighter the marble and the stronger the magnet the better off you'll be. Make sure you put a box a the bottom to catch your marbles.
What a great rainy day activity . . .
