Thought it was a load of rubbish? Think again!
Picture this...after a tiring drive, you reach your destination, and park in the car park. You pull your luggage out of the backseat, filling both of your hands. Maneuvering around, you manage to shut the open door with your back. Off you go. Almost to the door and then it hits you. You forgot to lock the car... Your car key doesn't have the range to reach your car across the car park.
Holding your car keys to your head will increase its range.
Simply hold the metal key part of your key fob against your head, then push the unlock button and voila! This simple but nifty trick turns your head into an antenna says, Tim Pozar, a Silicon Valley radio engineer.
He goes on to explain “You are capacitively coupling the fob to your head. With all the fluids in your head it ends up being a nice conductor. Not a great one, but it works.”
Or better yet, try it yourself!
