Collapsible water bottle

　　Remember those sci-fi movies where an entire meal came in a bite-sized morsel? What those tasty nuggets did for galaxy-hopping, 100% BPA- and taste-free Platy Bottles do for thirsty humans right here on earth. Compared to a hard bottle of equal volume, they weigh 80% less and take up a mere one fifth of the space when empty. Stash a few in your purse, breeze through airport security without wasting room in your carry-on, or just fill one with your favorite earthly grog and hit the trail. Collapsibility is versatility and you’ll wonder how you ever got along without it.
