I came across the Marble Run idea on Pinterest several months ago and started saving all my cardboard tubes. We didn't get around doing this activity until recently. Not only did The Toddler LOVE this activity, but so did the spouse and I! It's problem solving game to see just how you can get your marble to run all the way through the tubes without falling out.
We used acrylic paint (because that's all we have) and allowed The Toddler (equipped with a bib) to paint the tubes. And we painted them too. Because it was fun.
Be aware that if you give your child more than one color at a time, they may end up dipping their brush in EACH color before they actually begin painting.
And all those pretty colors may end up looking more like a greyish-olive green.
Like the paint on these tubes. But it's really ok, because this activity really isn't for us, it's for the kids...right? Right....
After the paint was dry, I hot-glued the magnets onto the tubes.
And then we put the tubes on the fridge
and played with them!
Ahhh!!! Rolling marbles through this is so much fun, I can hardly stand it!!
And when you are done with your tubes, you can also do this. What more could a kid ask for?
