The Demon
The Demon is a roller coaster in the Danish amusement park, Tivoli Gardens. It opened April 16, 2004 and features an Immelmann loop, a vertical loop, and a Zero-G roll. The riders experience G-forces of up to four times gravity while traveling the 564 meter-long ride.
It is a floorless roller coaster, i.e. the riders have no floor between them and the track. The total cost of the roller coaster was US$12 million and was the most expensive amusement Tivoli had built in many years. Dæmonen consists of a vertex, then a drop forming a loop, then a turn to a corkscrew, then it speeds up and suddenly brakes. All in all, the ride takes 1 minute and 46 seconds.
