The beach. Water parks. The toilet. These are all places where your beloved iPhone can find itself taking a nasty, warranty-voiding bath. Several items on the market purport to keep your gadgets dry in these situations, but how well do they really work? And do you have to spend a lot to get acceptable water protection? To find out, we put expensive gadgets into a cheap-o Waterproof Pouch from Meritline, a slightly less cheap-o DRY-PAK Waterproof Pouch ($14.99 with $3.99 s&h, a low by $6), an OtterBox 2000 Hard Case ($14.99 with free shipping, a low by $3), and a Ziploc Bag (free in most kitchen drawers). Then we submerged them in water for varying lengths of time. Each gadget bag took a 10-minute, 30-minute, 1-hour, and overnight dip in our science pool (read: fish tank) to see if they had what it takes to keep the evil water at bay. So what were our results? Like we'd ever tell you! We'd show you, though! Watch the above video for all the answers. Related DealNews Features: Is This the Worst Way to Cram People Onto an Airplane?
