Hello,
I have seen a video online that shows how a LED can be lit using a single lemon without using a copper and a zinc nail. They simply stick the LED into the lemon.
What does that work? I know the lemon contains the electrolyte but don't we always need to dissimilar metals for the battery to work?
thanks!
