Somewhere under there is some actual water!

From the boing boing website, I found a link to this wonderful bit of humanity.

Having been part of the great mass of bodies at West Edmonton Mall wave pool once or twice, I can only wonder at the ability of the Japanese to head for the wave that probably few of them can actually see...

Compared to this, West Eddies mall is but a Deserted Island with nary a soul for miles.
