- Start by filling your water bottle with water. Make sure to leave some space at the top to allow for the addition of food coloring.
- Add a few drops of food coloring to the water in the bottle. Start with the red food coloring and gradually add the colors of the rainbow in layers, with purple being the last color added.
- Secure the lid on the water bottle tightly and shake gently to mix the colors.
- If the colors aren’t as vibrant as you’d like, you can add a few more drops of food coloring and shake again until you achieve the desired color intensity.
- Once you’re happy with the colors, place the bottle in the refrigerator to chill.
