Crytal Radio- No power needed

Yes, Its an Earth friendly radio.
My friend VR2VHY, will explain how it works.
an antenna, joined to a copper coil with an compartment which touches a crystal and it will recieve the radio signals of nearby stations. And you can hear it from speakers or earphones.
------------------------------------------------------------------------------------------------------------
for some reason, it does not use any electricty... even for the speaker.
so go to your nearest electronics store and get it fast!


Its only 2 USD!
so no need to steal it!

So long, suckers!
