if you wanted to make a cool track you could get some stuff to make a buch of hills on plywood.(dont know what to use yet) Then you get alot of really fine sand paper that looks like sand and you put it on there. YOu could have like a starting and finish line and just go your own way. A n 8-4 piece of plywood that has dones all over it = unlimited possibilities and fun
