Step-by-step guide on how to make a rainbow battery

Step 1:

Gather materials To make a rainbow battery, you will need the following materials:

  • Zinc strips (can be found at a hardware store or online)
  • Copper strips (can be found at a hardware store or online)
  • A clear container (such as a jar or glass)
  • Water
  • Food colouring
  • Wire (preferably insulated)

Step 2:

Set up the container Fill the clear container with water and add a few drops of food colouring to create the desired colour. Repeat this process with different colours of food colouring to create a rainbow effect in the container.

Step 3:

Add the zinc and copper strips Insert one end of the zinc strip into the coloured water, making sure it is fully submerged. Do the same with the copper strip, but make sure it is placed in a different coloured section of the water.

Step 4:

Connect the strips with wire Take the other end of the zinc strip and connect it to one end of the copper strip using the wire. This will create a circuit, allowing electricity to flow between the two strips.

Step 5:

Test the battery To test the battery, you can use a multimeter or a simple circuit tester. If the circuit is complete and the battery is functioning properly, the tester should light up or give a reading on the multimeter.

Step 6:

Experiment with different colours Tries experimenting with different colour combinations and see how they affect the performance of the battery. You can also try using different types of metals for the strips, such as aluminium or iron, to see how they compare.

Overall, making a rainbow battery is a fun and educational activity that allows you to explore the principles of electricity and circuits. With a few simple materials and a bit of creativity, you can create your own colourful battery and learn more about how it works.


Rainbow battery indicator in iPhone

To create a rainbow battery indicator that shows the battery percentage and changes colours on an iPhone, you will need to use a third-party app or customization tool. There are a number of options available in the App Store or online that allow you to customize the appearance of the battery indicator on your iPhone.

Here is a general overview of how to customize the battery indicator on an iPhone:

  1. Install a customization app or tool on your iPhone. Some popular options include Battery Life and Battery HD+.
  2. Open the app and select the option to customize the battery indicator.
  3. Choose the desired colour scheme for the battery indicator. Some apps allow you to select a specific colour or gradient, while others may offer pre-set colour schemes such as a rainbow gradient.
  4. Enable the battery percentage display option, if available. This will show the current battery charge as a percentage rather than just a visual indicator.
  5. Save the changes and exit the app. The custom battery indicator should now be displayed on your iPhone.


Please note that customizing the battery indicator on an iPhone may require rooting or jailbreaking the device, which can void the warranty and potentially cause other issues. It is important to carefully research and understand the risks involved before proceeding with any customization.
