Gee...Why Didn't I Think of That?

Straight from the product's website (emphasis and hyperlink added):

"Using an ingenious gravity flow system, the PiMag™ Aqua Pour™ Gravity Water System can provide you with Nikken PiMag water no matter where you are."

Now...according to Dictionary.com, ingenious is an adjective that means:

"characterized by cleverness or originality of invention or construction"

So...you open the faucet, and gravity forces the water to pour out. Ingenious!

Pretty sure I learned about this in my third grade science class.
