Cave transformed into giant trampoline
The world's largest underground trampoline has been unveiled in a cave in Blaenau Ffestiniog, North Wales.
The unused cavern was once used as a slate mine but has been transformed by installing three giant trampolines.
The trampolines are reached by train, with each linked by a 60ft (18.28m) long slide.
