Totally Safe: Guy Builds His Own Coaster
John Ivers is a man with a dream. A dream of building a roller coaster in his backyard. And he did it, using nothing but scrap metal, his welding skills, and "the seat of his pants". This leads me to believe John has balls of at least quartz (a 7 on Mohs hardness scale). The coaster features a 360 degree loop and is ridden on what appears to be a 1986 Toyota Camry car seat attached to a lawnmower frame. Way to go John, that thing looks like a lot of fun. Well, as long as dying on a homemade coaster in the middle of bumf*** is still considered a good time.
Homemade roller coaster looks incredibly dangerous [dvice]
