If you ever lost your car in a parking lot there's an odd trick you can try to find your car. Simply hold your unlocking device up to your head and click it as usual. Viola! You can hear or see your car lighting up.
This was a weird strategy found on YouTube and Professor Roger Bowley of University of Nottingham, conducted an experiment to test the validity of this method. In the video above he explains how the trick works. Basically, holding the device up to your head means that it's electromagnetic waves of a certain frequency passes through a large number of water molecule in your brain. As the waves pass they pull the positive and negative charges in the water that generate radiating energy.
That's amazing right? If you still have doubts, refer to the video for more explanation and see the experiment.
