Ice-cube-tray in a bottle

The "Polar Bear Ice Tray" is a sealed bottle that makes icecubes and then facilitates their easy removal. The sealed container keeps freezer flavors away, and once it's all frozen, you can dislodge the ice by giving the bottle a whack on a countertop and then pour it out of the mouth. Looks like a clever way of solving an old problem, though I haven't tried it myself.
