We made this marble run with room 17.
It is called the Magic Marble Run. I got to paint the marbles on the marble Run. We used plastic tubes ,vacuum cleaner and hoses. We used old materials to make our marble run. When it was finished we tested it. This is a photo of me when I was about to put the marble inside it. It took 5 seconds for my marble to come out. It was so much fun playing with the marble run. I think everyone will really enjoy the marble run as well.
