Just when you thought partying couldn't get any crazier, we're here to introduce you to the next big thing (well, if you're a mermaid).

Underwater raving. In the world's deepest pool. WITH mermaids. Oh, and beer.

MTV travelled to Venice with Desperadosto experience a completely mad party that was the definition of LIT. Or, well, as lit as you can get when you're underwater.

They teamed up with party producer Elrow to create an unforgettable sub-aquatic experience in the Y-40 Deep Joy Pool.

The party saw over 400 guests taken down into the underwater wonderland that is “Deep House” -a42-metre-deep pool turned dancefloor, filled to the brim with disco lights, scuba diving mermaids and floating plastic bottles of beer featuring performances from world-renowned DJs Peggy Gou and Artwork.

From the surface, we sawbeams of multi-coloured lights blasting out, making thepool look like a liquid disco-ball. Once we were kitted out in brightly sequin-clad outfits, and fitted with our SeaTREK helmets, we were ready to go.

We climbed down a ladder deeper and deeper into the incredible dancefloor, and once we made it to a safe platform, the show began. Looking out from our platform we saw dozens of trained divers zooming about like super-heroes all around us,dressed as mermaids and other underwater characters, all while a kaleidoscopic laser light show refracted around us.

DJs Peggy Gou and Artwork were DJing from an underwater tunnel; sending surreal, sub-aqua sounds into speakers built inside our helmets. Absolutely bonkers, absolutely amazing.

Once we left the pool, we were greeted by staff who took us to the above pool rave, where we partied the night away with amazing beerslushies and mojitos (aptly named Despajitos).

As experiences go, it was incomparable and about as bucket list as they come.
