A daredevil has shared his madcap scheme to build a rollercoaster in his back garden, complete with a 10ft high drop.
Ben Tolliday, 19, had the idea to construct and ride a single-lane rollercoaster in March, and then took three weeks to build it in his parents' garden in Atlanta, Georgia.
He filmed his progress and his eventual successful ride down the track, whooping in delight as he sat in an old go-kart seat attached to his homemade wooden carriage.
