Finally we finished the marble run. We used metal clips to put on pipes, vacuum cleaner
hose, and big pipes. After we build a back round for the marble run to be a awesome. When the marble run was done we put the pipes on the back round we used metal clips also we used a screws to hold the pipes.It was so cool to have a marble run because the marble run goes very very fast.then when the teachers said that room 15 and room17 can have a turn on the marble run. We tried the marble run and it was very good because the marble was fast as a dog. I love to make a marble run because the marble run is very cool to with your family and then when you are finished you can try it out then you will be happy also I hope that you will enjoy the marble run.
