Underwater Cup-holder

I love to swim.  I love to drink.  These two facts lead to a very perplexing dilemma: where to put my drink while I am swimming?  Clearly one could not reasonably expect me to swim all the way to the side of the pool and put it on the deck where it could be kicked over by careless swimmers or worse, attacked by ants.  Perish the thought!  Enter: the underwater cup-holder.

One "Can-Cozy" plus one slug of lead weight equals the perfect fusion of the best summer has to offer.  Cheers, and stay thirsty, Chindogu.
