yeah so were maken one of these pain in the asses for physics but we need an ideas for a wheel. you used this foam like materiel for the huge back one but we need ideas for 2 front wheels(about the size of cd's). any ideas? we might end up just using the same materiel we did for the back. also the wheels have to be perfectly round.
