Question: Can a battery be made out of a potato? Can other fruits and vegetables make batteries too?

Hypothesis: A potato has acid inside that can act as an electrolyte and conduct electricity. So a potato can be used as a battery to power a small lightbulb.

Results: The first part of the experiment failed to light up the lightbulb. However, when the voltage meter was used, there was some power created by the potato, tomato, lemon and squash. A half a volt of power was produced for each fruit or vegetable. When multiple pennies, nails and wires were used, the meter showed a whoile volt!

Conclusion: The researcher discovered that there is not enough acid inside a single potato to create enough electricity to power a small lightbulb.
