Physicist uses brain as ‘radio transmitter’ to unlock his car — and you can, too

In a video recently published on YouTube, University of Nottingham physicist Roger Bowley demonstrates how to extend the range of an automobile’s keyless entry remote (or “key fob”) simply by placing it next to your head.

Calling it “an experiment to perform the next time you can’t find your car in a car park,” Bowley begins by walking twenty paces away from his car and using the key fob to make its lights go off. He then walks another fifteen paces, again presses the button on the key fob — only this time, the lights don’t go off.

“When I press the key,” he says, “nothing happens. But if I do it again with the key next to my head, something happens.”



“The reason this works is that everybody’s brain is full of water,” he explains.

Bowley then collects a jug of water and walks even further away from the car, until not even placing the key next to his head activates the lights.

However, when he places the jug of water on his head, and then places the key next to it, the combined effect of the water in his brain and water in the jug cause the car’s lights to illuminate.

Bowley explains that when the key fob sends the electromagnetic waves through the water (H2O), they pull the positively charged hydrogen ions in one direction, and the negatively charged oxygen ions in the other.

“In effect,” he said, “you’ve got the protons being pulled upward, then downward, then upward, then downward, because of the oscillating electric field. That means they’re behaving rather like a radio transmitter — as they go up and down, they’re radiating energy.”

Because that energy is being radiated at the same frequency as the key fob’s signal, the fob can effectively communicate with the car well beyond its typical range.
