Human Antenna is a carpet radio that uses body as an antenna. And you can walk on the carpet to change the radio frequency(watch the video).
A carpet made of looms from conductive thread. By standing on it, your body acts as an antenna. The carpet picks up the radio waves, which your body receives and makes them hearable. When walking on the carpet you can tune it to a certain frequency, like the tuner of a radio.
