7 Surprising Uses for Plastic Wrap

The beach and technology do not mix: moist air can harm electronics and sand can create scratches and get stuck in your phone's ports. If you're in a pinch, LifeHacker has a brilliant plastic wrap trick to help keep it safe.

Try It: It's simple: just wrap your phone in a thin layer of plastic wrap. The touch screen will still work while protecting the nooks and crannies from filling with sand.

Why It Works: Sand can't make its way into your phone with a layer of plastic in the way. But water can (it is, after all, just plastic wrap) and avoid keeping it wrapped up for too long, since sealing it up for a while can cause it to overheat.
