It’s high time we reconnect with the kid inside us because the world’s largest underground trampoline has just been unveiled in Blaenau Ffestiniog, North Wales, in United Kingdom. Bounce Below is a network of trampolines and slides mounted to the walls of an abandoned slate mine at dizzying heights of up to 180 feet above the ground. To pump up the adrenaline, kids and the young-at-heart can climb, bounce, slide, and jump in the netting amidst a dazzling technicolor light show.

But please do not enter with a full stomach in case you get a serious case of the heaves, which may be detrimental to everyone below.
