I have seen people use toilet paper and paper towel tubes (the cardboard center of the roll) to make things with toddlers… a way to begin tinkering and making their own toys. I decided to try building a marble/ rock drop because my granddaughter, 16 months old, also loves collecting rocks.
First we saved several rolls. We then cutout a “u” shape at the opposite sides of each end of the tubes, then painted them. I used a spray enamel to coat both the inside and outside for the waterproofing advantage it would give. We chose bright colors… red, green, yellow, blue.
Painting turned out to be more challenging than I anticipated. The tubes are light weight cardboard. They are far more absorbent than I had anticipated, and I had to apply several thin layers to get a relatively even coat. The light weight of the tubes caused them to fall over easily in the light breeze that was blowing in our backyard. The wet paint got on other tubes, the table, my fingers… absolutely anything they touched before they were dry. I also had to do a lot of touch up that I didn’t expect.
Once dry, I attached little square patches of Velcro hooks to the sides of the tubes so my granddaughter could move the tubes around and play with different configurations. We attached them to a 3’ square piece of felt suspended vertically with long flat sticks at the top and bottom to suspend the fabric and weight it at the bottom.
Simple enough design. I didn’t have the felt attached to a solid backing. My thought was if I can have the felt somewhat loose and just have the weight at the bottom, it would be pretty easy to store when we’re not playing with it. It moved too much, however, and made it harder to apply the tubes. The Velcro- tubes tended to roll somewhat sideways, which affected the alignment of the “u” cutouts. It took several tries to get rocks to roll from the top, through the tubes, to the bottom.
My granddaughter caught on quickly, and she enjoyed the concept of dropping rocks and watching them fall. I got caught up in the execution of the process, and was flustered that the tubes were more flimsy than when I was younger. It was pretty easy for my granddaughter to squash the tubes, which made harder for the rocks to roll down. Certainly not a very durable toy as it is currently constructed, but the process was fun.
I would add a picture, but I’m not quite sure how to do that.
