first, marbles are hardly ever used ball bearings are. Second, ball bearings are smooth and the perfect size for a machine which has a size limit. third, anything larger will shake the machine causing steps to go off prematurely, and fourth, they are easily obtained
i'm no rube goldberg x-pert but why do all of them envolve a marble. If i was a judge, i would take pionts of origanality cuz everyone uses marbles. it would be nice if someone didnt use a marbe and used something else that rolls.
nice but could be better quality

If you had all of the machines, full length, you would have more comments, and ratings, but it was okay.
