So right about now you're thinking... man. I really need to run to the store to stock up on drinking water for when WE get hit by a natural disaster not unlike Hurricane Sandy. BUT MY BACK HURRRRRRRTS.
Well, save that aching back and buy The Water Bob instead! It's a giant rubber bladder you put inside your tub, fill it up with 100 gallons of water, and then drink... drink... DRINK your way out of a dehydrating natural disaster. Or you could put vodka in it—which is what I would do. WATCH.
