This is the world's coolest bounce house

Bounce houses are the coolest thing parents can rent for a kid's birthday. They're definitely better than clowns, too, in that they hurt fewer children. But you know what's even better than a bounce house for kids?

A bounce house for adults. In an abandoned mine.

Bounce Below -- quite possibly the world’s coolest trampoline system and quite certainly the largest, with 10,000sqft of nets -- just opened up in the cavernous belly of an abandoned slate mine in Blaenau Ffestiniog, North Wales. The elaborate setup consists of three stacked trampolines suspended between 20 and 180 feet above rocky, jagged, certain death. But don't let that spoil your fun.

To get to the underground jumping paradise, visitors have to board an old mine train, put on special overalls and helmets, and then slip down a 60ft slide that leads straight into one of the trampolines, which is connected to the other two by walkways, slides, chutes, and ladders. 

It's like everything Indiana Jones did in Temple of Doom, but with way less ripping out of hearts.

And if bouncing around in a 176-year-old, 200 x 60-ft slate mine most recently used for hiding art from Nazis weren't enough, the whole experience gets a disco effect from technicolor LED lights trippier than a Phish concert.

And no, these tricks aren't just for kids. Bounce Below plans on using its psychedelic space for bachelor and bachelorette parties, and even weddings and co-ed slumber parties.

Co-ed slumber parties are a thing?

Check out Bounce Below here. There's even a "serious" Victorian mine tour of its history narrated by a 12-year-old miner. And yes, that's with an E. And it's definitely a lot weirder.
