"What happens when you drop an iPhone 4 into the sound hole of a guitar, position it just so, and then pluck the strings? Take a look at this video to find out.\nReminding us of that Les Paul Google doodle we showed you last month, this is not what guitar strings are really doing when you're strumming away. \nThe strings look wavy because the iPhone's rolling shutter isn't exposing the entire string all at once, but in a slightly different rate from their vibration. It's an effect similar to the way spinning wheels look when shot on film \u2014 as if they're spinning backwards. \nWant to shoot a video like this yourself? Here are some tips from \"justkylevids,\" the talented guitarist who shot this video: \n\nYou must have the strings brightly backlit to get the camera to capture at such a high frame rate (pure conjecture). You can see how the effect fades when the buildings come into view.\nUse a pencil [to position the iPhone inside the guitar]\nThis was used with the front facing camera, try the back camera, it may capture better!\n"^^<http://www.w3.org/2001/XMLSchema#string>
