Summary

In this DIY tutorial, the process of creating a simple battery using copper coins is demonstrated. The materials required include cardboard, vinegar, aluminum foil, a marker, a pencil, a LED diode, and tape. The steps involve cutting circles from cardboard and aluminum foil, soaking the cardboard in vinegar, and assembling the battery by layering coins, cardboard, and foil. Once assembled, the battery successfully powers a LED, showcasing the power of oxidation from the copper. This project highlights a simple yet effective way to create a functional LED light using basic household materials.

Takeaways

• 😀 You'll learn how to make a battery using copper coins.
• 😀 The materials required include cardboard, vinegar, paper, aluminum foil, a marker or pencil, a LED diode, and copper coins.
• 😀 Start by drawing small circles on the cardboard using a coin, then cut them out with scissors.
• 😀 Repeat the same process with aluminum foil, marking and cutting out circles.
• 😀 After cutting, you should have six cardboard circles and six aluminum foil circles.
• 😀 The next step is to dip the cardboard circles in vinegar.
• 😀 Assemble the battery by layering the materials: coin, cardboard, and aluminum foil, in that order.
• 😀 Ensure the layers follow this sequence: coin, cardboard, and foil for each section.
• 😀 Once the battery is assembled, use electrical tape to secure it and hold everything in place.
• 😀 Leave a small gap to connect the LED, then test it to see if it works, lighting up with full brightness.
• 😀 This experiment demonstrates how copper oxidation, along with just six coins, can generate enough power to light a LED.

Q & A

What materials are required to create the copper coin battery?

The materials required include cardboard, vinegar, paper, aluminum foil, a marker or pencil, a diode (LED), and copper coins.

How many circles of cardboard and aluminum foil are needed?

You need six circles of both cardboard and aluminum foil.

What is the first step in creating the copper coin battery?

The first step is to draw small circles on the cardboard using a coin as a template and then cut them out with scissors.

What should be done after cutting out the cardboard circles?

After cutting out the cardboard circles, you should repeat the same process for the aluminum foil—marking and cutting the circles.

What should you do with the cardboard circles after they are cut out?

Place the cardboard circles in a small container with vinegar, so they can soak up the vinegar.

What is the process for assembling the battery?

To assemble the battery, alternate stacking the materials in the following order: a coin, a piece of cardboard, and a piece of aluminum foil, repeating this pattern until all six coins are used.

What is the purpose of using tape in this process?

Tape is used to hold the stack of materials tightly together, ensuring that the components stay in place.

Why is there a gap left in the tape?

A small gap is left in the tape to allow for the connection of the LED.

What happens after the LED is connected to the battery?

Once the LED is connected, it should light up, demonstrating that the battery is working and generating sufficient power.

How does the copper contribute to the battery’s function?

The copper's oxidation process plays a key role in generating electricity, which powers the LED.
