Is that triboluminescence in your pocket, or are you just happy to see us?

 
Forseriously though...  Just rub our Flash Rocks together to see a totally natural piezoelectric rock show!  They'll glow internally and emit a distinctive odor!
 
If you're lucky... someday soon you will be holding electric potential in your hands, so you can see for yourself.  Flash rocks - aka quartz - are one of the few minerals with piezoelectric proprieties.  So, when subjected to mechanical stress, these two little rocks generate an electrical charge.
 
Just place a rock in each hand, and forcefully rub the rocks together.  To see the glowing electrical effect fully, you should do this in a darkened room.  Also, note the distinctive odor given off by the frictions.
 
Made in the USA.  Stone size varies.  Card measures 3.5 inches wide x 6 inches long.
