He Sticks Some needles Into A Lemon. Seconds Later, I Can’t Believe What I’m Seeing!

What You’ll Need:

• 1 large lemon
• 1 zinc nail (like a galvanized nail)
• 1 copper wire or copper nail
• 2 metal needles or wires
• Small LED light or digital clock (optional, to see it in action!)

How It Works: The Science Behind the Scene

A lemon contains citric acid, which acts as an electrolyte. When you insert two dissimilar metals — like zinc and copper — into the lemon, a small chemical reaction takes place.

Here’s the simple breakdown:

• The zinc reacts with the acid, releasing electrons.
• The copper acts as the positive terminal, receiving those electrons.
• Connecting the two with wires allows electricity to flow — just like in a battery!

And yes — it can produce enough power to light up a tiny LED or run a small digital watch!
