This clock burns with the power of lemons. No, really. This is a digital clock that is powered by citric acid. The wood plank has two spikes of copper and zinc built into it. Put half of a lemon on each spike and be amazed at how it runs on a single lemon for an entire week. It’s magic.

I love the concept of these Ice and Slices trays. Slice up a lemon or a lime, put it in the tray, add water and freeze. Presto. Next time you have a vodka cocktail or something equally fruity on the rocks, you can just drop in a few slice cubes of lemon or lime. Genius! Only a mere six bucks.
