PURPOSE: To demonstrate that radio waves cannot penetrate a Faraday cage.

DESCRIPTION: The radio is tuned to a good station so that everyone can hear. Lowering the screen Faraday cage over the radio stops the radio waves, and the sound of the radio ceases.

SUGGESTIONS: Use only a battery powered radio. Using a AC power cord may cause this demo not to work. This is because the cord can act as a antenna.

EQUIPMENT: Portable radio without a AC cord, small mesh screen Faraday cage.

SETUP TIME: 30 Min.
