Indoor Water Park... Say, whaaa?

Backblip.

Yes, ladies and gentlemen, it is possible to build a water park indoors. Not sure why one would have a water park indoors, but some of us thought this was the best thing since Christmas. To be honest, I partook as well: the slides are 4 story high, with the tubes on the outside. One was lit, one was dark. I preferred the lit one, as it was MUCH more twirly.

This attraction is called "the river". You plop your rear end in a tube thingy, and the current twirls you about and in a loop.

Why not...
