Bendy-Straw Marble Roller Coaster. This is a marble roller coaster machine built completely out of bendy and straight straws. The project was for a Junior-year Honors Engineering/Technology high school class. Our instructions were simply to build a marble roller coaster on a 3x1 foam board completely out of straws and hot glue. The machine was built in two weeks, from the bottom up. The Pink track was built completely first, and then the Green track was added. Each track is shown, followed by a break-down of each of the special elements of each track. To wrap it up, there is a video of both tracks running at the same time. Background music is "Grace" by Apocalyptica ft. Tomayasu Hotei (2007 "Worlds Collide" Sony BMG, all rights reserved).
