Not a good builder

Postby Harkins » Sun Sep 09, 2007 9:36 pm

Got to build a structure that will allow a marble to drop vertically in 20 seconds. Has to stand 70cms high, can use tube, containers, tape etc. The marble has to pass across/through a minimum of four different materials/structures. I also must lable all forces for the trip, push and pull. :? :? :?
