Orange Juice is a common household item in the refrigerator.

Did you know it could also do this?

A galvanic cell is made from a combination of a magnesium strip, a copper strip, and juice in a beaker. The current from this cell is used to drive a clock normally powered by a DC battery.

Voltage versus Time

There is no narration for this video.

Here we see a chart recorder making a record of the voltage generated by the cell as a function of time. The voltage drops each time the clock ticks. Why do you think that is?
