Hey, for this project how did u stabilize or bend the tubes, we have to build a roller coaster, how did you make it so that the tube banks and is straight and everything? :) PLEASE
what is with this unsupported tubing? Sort of a cheating way to lose the energy and speed of the ball. We had to use the track clips, to keep the energy of the ball sustained. But my group reduced them out of a desperate attempt to finish the coaster in the alloted time and get it to work.
=/ if anything, sustaining the energy means you can possibly fit one more loop in. If you wanted to "desperately" finish in the allotted time, then simply but a stopper at the location of the allotted time, simple as that really.
hey man sick roller coaster. i was wondering how you keep those tubes close together like that. do you use tension , or something to keep them together
what is that track made out of ? i am building one now for physics and i am using a steal ball like that as the object that has to go on the roller coaster. i was just wondering what it was

I think he uses pins to keep it together, we did something similar for my physics class.

why don't you use this one in the contest? This one has 2 more loops.

did you heat this to bend it or just use force then secure it and where would one buy set tubeing
