Love science? Looking for a natural, eco-friendly and semi-old way to tell time? If so, you'll love The Citrus Clock by Anna Gram, a normal childhood science project fashioned into home decor.

The Citrus Clock works the same as powering a clock with a potato. The natural acids substitute the need for a battery when they come in contact with metals like zinc and copper, which creates an electric current.

If you'd like to make your own citrus-powered clock, instead of buying one from someone else, the cost to do so is minimal. Different websites may alter their directions a bit, but the basics are [aluminum foil, metal clips, copper wire](https://www.trendhunter.com/trends/moov-and-coo), and an inexpensive [LED battery-powered clock](https://www.trendhunter.com/trends/regenbox-1).

Come to think of it, with Christmas vacation just around the corner, you may find making a lemon-powered clock on your own to be a fun, hands-on science experiment to do with your children. Unless you got really creative, however, with aluminum and copper wires all over the place, it would look more like a science project than a present.
