See those silver stripes around the circumference of this Parrot AR drone? They're not there for decoration or style. They're actually strips of aluminium tape that's wired into a capacitor from a disposable camera's flash. It means that when — not if — this drone bumps into someone, they're going to get a particularly unpleasant shock, as you can see what happened to its creator's arm.
And if you've ever been at the controls of one of these flying drones, you'll know that piloting it around a room without bumping into anything — or anyone — takes quite a bit of practice. So if you're a novice pilot, trying this hack yourself is just about the stupidest thing you can do — unless you record the results and post it to YouTube for everyone's enjoyment.
