This fruit clock will be really amusing and a cool conversation piece for the first few days you own it. You can tell all your guests about how it runs completely off the fruit, and how it uses the original scientific principles on which all modern electrical storage batteries are based to power itself. Isn't that just so cool? But around day 4 or 5, when the orange is starting to get rotten and/or eaten, you'll realize the very basic flaw in the design of the clock: you'll need to stick it in a new piece of fruit every few days and, presumably, reset the clock each time. Sounds like a lot of work for a pretty dorky clock. It's available online now for $15. — Adam Frucci
