Aside from making Play-dough this weekend while recovering from a virus, we made this marble maze. We taped toilet paper rolls, pie boxes, egg crates, etc to the window so the tape wouldn't take paint off our walls and had fun playing with this Marble Maze for an hour or so. Wish I had more paper towel/toilet paper rolls! Time to start saving them up. We used what we could find as you can see. But it worked!
