Lots of cellphones die from drowning (raise your hand if you've dropped yours in a puddle, washing machine- or the toilet). In the past, if you wanted to waterproof your phone, you had to buy a special plastic case or pray that the rice trick would revive it.
But a solution may be at hand. Tech research company Liquipel has invented a new technique that covers devices, inside and out, in a razor- thin, nearly invisible waterproof shell. When water hits the device, it beads up and rolls off, leaving the phone or tablet dry.
In a test, Popular science editors sent an iPhone 3GS to Liquipel for waterproofing. When they got the phone back a few days later, they turned it on and ran it under a tap five minutes. The phone operated normally while under the faucet. Afterwards, the touch screen was slow to respond at first, probably because of water droplets on the screen that hadn't yet rolled off, but after a few seconds, the phone worked as if nothing had happened.
The waterproofing costs $ 100 plus shipping. The company accepts iPhones, iPads, Samsung Galaxy handsets, Motorola Droids, and other brands and gadgets by mail to its California offices.
