Step 1: Creating the Batteries
Using the knife, slice a penny-sized slit on the right side of your lemon.
Push the penny far into the lemon, leaving a small area to hook your alligator jumper to. This will be your positive terminal.
Now, create the negative terminal for your battery. Stick one of the galvanized nails into the left side of the lemon, about 2 inches away from the penny. It is important to have the nail and penny separated. If they touch, it will cause a short.
Repeat this process until you have 4 complete batteries.
Step 2: Adding the Jumpers
Make sure the lemons are aligned parallel to one another.
Attach one of the alligator clips to the nail (negative terminal) on your first lemon.
Then, run the second jumper wire from the penny (positive terminal) of the first lemon to the nail (negative terminal) in the second lemon. Add the rest of the clips, alternating positive an negative, until all the lemons are attached
Step 3: Lighting the LED
Connect the first jumper wire from the nail to the negative connection on the LED. The negative connection on the LED is the shorter wire nearest the base.
Then, clip the jumper wire from the penny of the last lemon in your chain to the positive connection on the LED. When you complete your circuit, the LED will light up!
Experiment with different fruits and vegetables to see which one produce the most volts! The higher the voltage, the brighter the light. The average lemon produces just under 1 volt. We need at least 3.5 volts to light up an LED. This is why we need 4 lemon batteries.

Battery from four lemons:
A lemon produces average of 1 volt. The voltage required to light a LED is 3.5 volts. So, 4 lemons are required to light a LED bulb.
Follow the following steps to light a LED:
- Arrange 4 lemons as a line.
- Create two incisions in each lemon.
- Leave at least 2 inches of gap between the two incision. If not, both the charges will collide and it will create short circuit.
- Insert galvanised zinc nail in all of the left side incision and insert copper coin/piece in all of the right side incision.
- Using alligator clip lead connect coin in the first lemon with the galvanised nail in the second lemon. Likewise, connect all the lemons with alligator clip leads.
- Now, nail in the first lemon and coin in the last lemon are left unconnected.
- Take an alligator clip lead and connect the nail with negative connection in LED. Connect the copper with positive connection in LED through alligator clip lead.
- Now, the LED lights up.
Here, the acid in lemon acts as electrolyte. Zinc and copper acts as metals in the electrolyte.
