Rollercoaster.......for a marble not me.....

 Today we made roller coasters that had to have certain features such as hills, valleys, loops and ect . The roller coaster you see in the picture is the feature of a hill.  Taping it to the wall to hold it up was very helpful so that it could stay up. At the end of the rollercoaster was a can so that when you rolled the marble down the rollercoaster it flew into the can. Try It!!
