🧪 What You Need:

• 4 to 6 lemons (fresh, juicy ones work best)

• Copper pieces (like pennies or copper wire)

• Zinc pieces (galvanized nails or zinc washers)

• LED light (a low-power one, like red or green)

• Wires or alligator clips

🔌 Steps:

1. Insert metals into lemons: Push one copper piece and one zinc piece into each lemon, about 2–3 cm apart (don’t let them touch).

2. Connect in series: Use wires to connect the zinc of one lemon to the copper of the next.

3. Leave two free ends: One end with copper (positive) and the other with zinc (negative)—these go to your LED.

4. Connect to LED: Attach the free wires to your LED’s leads. If it doesn’t light, flip the LED around (it’s polarity-sensitive).

5. Watch it glow: If everything's working, the LED should glow dimly.

⚠️ Reminder:

• 12 lemons might light an LED, but they won’t charge your phone—not even close!

• Charging a smartphone needs watts of power, lemon batteries provide only microwatts.
