Marble Run

Not too long ago, I challenged my group to create a marble run out of recycled materials.  On the table I put a shoebox, 5 paper tubes, a small plastic drink bottle and the only way to hold it together; tape!  I asked them to examine the items and draw up designs we could collaborate. 
The first design had the tubes going from top to bottom, which didn't result in the amazing thing they had hoped for...but, the children persevered.  They decided the tubes would need to be cut and redirected to the sides.  We tested out a couple designs until we came up with the final result:

It has become a favourite for children and adults alike!  Perhaps this summer a large scale version will be in the works???
