What is something I can use to make the bumper on the proton pack's cyclotron? I need good Ideas and fast! I have to have my pack finished by friday morning, and the bumper is one part I can't find. but beggars can't be choosers, so any tips, anytime are helpful. Thanks

i have heard of ppl using the olf hot wheels tracks for the bumper, and from what i have hard a seen they are pretty good.
