Crystal Radio

Radios are all around us - playing in cars, boom boxes, space shuttles, etc. - and radio waves are all around us - literally all around us, in the very air we breathe - and now you can harness the power of both, and have a great time doing it, with the Crystal Radio! It actually operates without batteries, and comes with a book that gives you the inside scoop about radios in a fun and informative way. Simple to build, simple to learn, and very entertaining, the Crystal Radio teaches important lessons about an important part of our world.
