Someone showed me a picture of an underwater slide from an image site a while back. This got me interested, as I love the sea. And drifting on a little current between fish sounded like heaven to me.
After a little Googling, I managed to find this picture, which is in the Atlantis Hotel, in Dubai.
Are there any other places that have underwater slides? I would love one that actually goes through the sea, not an aquarium, like the above, but I can see how that would be difficult.
