Video of The Abyss water slide at The Atlantis at Paradise Islands, the Bahamas.  This ride is located at the Power Tower. It is part of what they bill as Aquaventure a 63 acre waterscape.  See a rare first person view of the slide as you are taken down the almost vertical 50 foot descent, through the twists and turns of the slide in total darkness, and then tossed gently into tranquil waters .
