Blackpool Pleasure Beach, Blackpool, England

The planet's first looping 'coaster running entirely over water

This is the hair-raising ride being put through its paces at Blackpool Pleasure Beach. The £8m beast whisks riders upside down an amazing five times and soaks each passenger with jets of water from its huge fountains.

Infusion will be open to the public this summer and is expected to attract record numbers to the Pleasure Beach. Andy Hine, chairman of the Rollercoaster Club, said: "The G force is incredible - not quite a rocket taking off, but you can't move."

Come with us as we take an exciting ride through the world's scariest white-knuckle rollercoasters.
