Hey guys i just built a track bout 1 or soo it took me i just took a piece of corplas and then took my dads old hotwheels track( opps lol ) and i stood it up on its side and took electrition tape and taped it into a track formation with little piece holding it along he way so if u try 2 ride the wall the little pieces of tape will sloww u down like gravel so it is pretty kool try it it wll work like a charm that way if u have some corplas or card board just go get that old hotwheels track from the basment or pick some up at a garage sale and start buildin(u ne tape 2) so what u guys think
