The fruit clock is a digital clock/calendar powered by fruit. While emulating the original battery invented by Alessandro Volta over 200 years ago that utilized lemon juice, the creation of whole fruit in the mid-1900s has allowed the experiment to be perfected with artistic flare.
The kit includes jumper wires, time display, rubber stop and frame for its $14.95 pricetag. And don't feel bad while people are starving in the world as you destroy the food supply for a "conversation piece". You read Gizmodo, and are therefore a decent person (though you probably smell a little funny, honestly).
