Andrew Gatt | 2014 USA Science & Engineering Festival Paper Roller Coaster @AndrewGatt | Uploaded June 2014 | Updated October 2024, 13 hours ago.
I built this paper roller coaster for the 2014 USA Science & Engineering Festival in Washington, DC. The coaster was one of my better small coasters. The funnels worked almost too well. I wanted it to be a racer with two tracks for two marbles. I added a small bump to the lower funnel so that it would be a fair race. Without that bump, whichever marble went down the path with the second funnel would always lose.
