Hello and welcome to SciShow experiments.
Today we're discussing what may be the most cliché and well-known science experiment of all time.
Though it is also one of the most misunderstood science experiments of all time.
The important thing to note here: the electricity is not in the lemon.
First, let's do this thing.
Now roll the lemon around a bit, to break up all of the little juice packets inside, to get it nice and juicy.
Stick a nail in one side—it has to be a galvanized nail, meaning it's coated in zinc.
And on the other side, stick something copper.
I'm using copper wire.
You'll probably be unsurprised to discover that when I connect this volt metre to the copper and zinc, it will show some electric current.
