Suncatchers as familiar objects in most peoples lives, and crystals collect and refract light in home windows entertaining us with glistening and colorful light patterns to our eye. Light is an electromagnetic radiation that we can see. Radio waves are also an electromagnetic radiation, but we cannot see them. Antennas collect and guide radio waves through wire to receivers like radios, cellphones, and TVs that in entertain us with music, voices, images, and videos. The crystal radio that is going to be built is like an Rfcatcher that captures and reflects voices and music.
