Don’s ask me why I have been saving toilet paper rolls, but they get handy for so many projects! I made this marble run after watching Lukas to play with one of the big wooden one in the store. Building without an exact plan, just cutting and gluing the tubes to fit and make the run interesting. Didn’t take more then half an hour, cardboard box, tubes and hot glue gun. There are to starting points (top and back) and they connect at the front. I have never got to photograph Lukas playing with it (sadly) and because we have been playing with it for over 2 months now, I’ll better to post at least these pictures before we recycle it. It won’t be end of the fun, I am hoping to make a magnetic version one day.
