Pop Quiz, Water Bowls in front of speakers

OK, here something entirely different. See if anyone can figure out how the Frog Jump in Water Sound Tweak works. This Machina Dynamica tweak was first exhibited at CES in 2005 in the Golden Sound room, along with the original Intelligent Chip, Brilliant Pebbles and Ultra Tweeters, the 1 MHz tweeters. The Frog Jump in Water Sound Tweak involves filling two medium size bowls with cold tap water and placing them a couple feet in front of both speakers on the floor. Please, no jokes about how they make the sound more liquid.

A prize for the winner.

Ok, I know what you're thinking

Playing hard to get, eh. OK, Then here's a few hints. First, it's got nothing to do with humidity. Second, it's got nothing, or at least very little, to do with the reflection of sound waves off the surface of the water.

Is it the coldness of the

Is it the coldness of the water that acts to cause the air in front of the speaker to slightly condense, thus transferring more energy from the loudspeaker

You're warm. Very warm.

The cold water actually slows the bottom portion of the acoustic wave near the floor (speed of sound slower in cold air), forcing the top portion of the wave to "break" or curl downward toward the listener. Analogous to why a wave breaks on the shore when the bottom of the wave is slowed by the friction of sand on the beach.
