marble Run

Last week we finally put everything together.  We used the metal clips to put pipes onto the board so they don’t fall off.  Today we tested the marble run. At morning tea we were testing how long it takes for the marble to get through the tubes in 1 minute.  Mine took 4 seconds. When I was painting a mushroom  I was thinking that every will like the marble run .  I hope that every one will say it works very well .
