Did You Know...
...that the Eveready Battery began as an invention called the "electric flowerpot," which was a tube with a battery and light bulb inside? The idea was to fasten this gizmo to the side of a flowerpot so it would illuminate the flowers from the bottom. The idea died on the vine and the businessman who licensed the flower pot, Conrad Huber, was left with a pile of useless tubes -- until he found a way to market them as batteries to light the world!
