It's a dilemma faced by sugar-water drinkers the world over. If you screw a lid back onto a soda bottle too tight it can be almost impossible to open. Too loose, and you risk losing all the carbonation. But these clever Sodavalves solve both scenarios by providing extra leverage for opening and sealing a plastic bottle.
Available in two versions—designed to look like faucet handles, or the giant wheels used to seal off pipes and doors on a submarine—the Sodavalves are far easier to grip and turn than your standard plastic bottle caps. Which means you can seal a bottle tighter to minimize the slow leak of carbonation, but still easily open it the next time you're thirsty.
