These giant trampolines are 100 feet underground
Hidden 100 feet below Earth's surface is a one-of-a-kind playground for the explorer in all of us. North Wales in the UK is home to an underground cavern, covered in lights, trampoline-like nets and slides.
Called Bounce Below, each person gets overalls and a helmet before taking an old mining train down to the 176-year-old cave. The giant bouncy nets are hung in two huge chambers, linked by slides and walkways.
The best thing about it? This playground doesn't get rained out, so it's open all year.
