Re: CardBoard Rollercoaster
The key to bending cardboard smoothly is (much like wood) to use thin pieces (corrugated is right out) and glue them together in a form, and when the glue (elmer's) dries the shape is maintained. Trying to bend a thick piece will result in frustration.
The tighter the bendm the thinner the cardboard must be. I guess the thinnest you'd ever need is plain paper. For a 10" loop use 0.010 poster board, maybe 0.020 shirt board.
