I wanna do something with like a potato and a sweet potato. Like which one conducts electricity the best? You know that experiment with the potato (or lemon & lime maybe) making something work, but I forgot?
OR JUST GIVING ME A WEBSITE WITH MIDDLE SCHOOL: 8TH GRADE PROJECTS I CAN DO... I only have 12 days. Lol...

The secret to the potato clock is not in the potato, it's in the electrodes that are stabbed into the potato. They're made of different metals that react electrochemically. The potato is only a buffer across which the metals can react at the correct speed to run the clock.
A more interesting project might be "batteries from common household objects." According to the rules of the thing, you probably have to arrive at a result by experimentation.

Get your potato. Cut it in half. You need two strips of different metals. insert them into the half of the potato, they must not touch. You will need to attach a voltmeter to the metal strips. It will not give enough current to light a bulb.
