Big One

The Big One, formerly known as the Pepsi Max Big One, is a steel roller coaster located at Blackpool Pleasure Beach in Blackpool, Lancashire, United Kingdom. Designed by Ron Toomer and manufactured by Arrow Dynamics, the ride opened to the public on 28 May 1994 as the tallest and steepest roller coaster in the world. It held the record until July 1996, when Fujiyama opened at Fuji-Q Highland in Japan. The ride is currently the tallest roller coaster in the United Kingdom.
