We had a long heavy cardboard roll from a rug that we purchased and the boys had been begging me for it. I finally figured out something that we could do with it that didn't involve them beating each other....hopefully. We made some rain sticks. We just cut the cardboard tube to the desired length. You could also use a paper towel or wrapping paper roll. I like how thick ours were though. Then along the spiral seam that runs the length of the tube we put 1" wire nails every 1/2" the entire length of the tube. Then we taped up one end and put tape down the spiral covering the nails. Poured in some rice and then taped up the other end. We let out some stickers and markers and TA DA! They have some rocking rain sticks.
