Can't find your car? Hold your key fob up to your head. (Really.)
Next time you're wandering through a vast parking lot, looking for your car, there's a weird strategy you can try: hold your remote unlocking device up to your head.
It might sound pretty crazy, but it will actually extend the device's range a bit — perhaps causing your car to light up, letting you more easily find it.
We were skeptical too, but a few physicists have actually conducted some experiments that prove it's true.
