Huh? No, I don't think they're copyrighted. They're just a clever trick. They work on a similar principle to the used by many water polo (and evil scuba instructors) coaches to train. Take a 5gal. bottle (like a Sparklett's bottle), fill it with water, and drain it while treading water. It is one HELL of a workout, because the only way that water is gonna drain is if you keep the opening raised over the top of the water. Good thing fresh water is only 8lbs./gallon, huh?
