Marble Run

Today we have finished our marble run. We used metal clips to hold the tubes that people put in
the rubbish. We screwed some screws on the metal clips to hold the tubes on the board.
We used vacuum pipe hoses and tubes.  We did a wiggle line. We did the wiggle with the vacuum
we did the lines with the tubes.  Then we tested it.  The marble took five seconds to go down.
I hope people will like playing with it like we like playing with it.
