The only way to know for sure stick two coins of different alloys in a lemon and measure with a meter.

Some people use a potato.

I "think" usama was referring to a battery constructed like the following:


It's the same principle and the same answer build it and test it.

Any pairs of different metals will work.

Try combinations of all three, see which works best.

(Thas called "science".)
