Meet the Potato Clock: a geeky clock that lets you power it using two potatoes, fruits, or cups of salt water. You don’t need a battery to get it to work nor do you have to connect it to an electrical outlet. You get a digital clock with wires, pots, connecting wire, transparent tapes, copper and zinc strips and detailed instructions. Makes a great gift for curious kids.
