Natural Skimmer? ITS TRUE!

Saw this in Connecticut when I visited for passover and thought it was pretty cool. I know most people have already seen this, but just thought the simplicity and efficient of this natural skimmer mechanism is remarkable.



Makes you think about revolutionizing skimmer design, basing it on agitating water rather than shoving in bubbles
