I got the idea to do this while watching Trevor's slow motion videos. I stood for several minutes taking video of each coaster and sped it up. If I get 10 likes on the video I will make more with pompeii, mach, etc. Enjoy!
P.S. Sorry about the watermark. I took the video with my camera with a .mov, and Windows Movie Maker doesn't work with that, so I had to convert it to .avi. So sorry about that!
