Baking Soda Lava Lamp

Baking Soda Lava Lamp | Science Fair Projects | STEM Projects
You can easily make a lava lamp at home with science! Explore the reaction between baking soda and vinegar, and observe how water and oil don't mix, as you create a bubbling, colorful display.


The hypothesis is that when baking soda reacts with vinegar, it will create bubbles that rise through the oil, resembling a lava lamp.

Method & Materials

You will carefully layer baking soda and then oil in a bottle. Next add colored vinegar using a pipette. Observe the reaction as bubbles form and rise, creating a captivating lava lamp effect.
You will need baking soda, a clear bottle, vegetable oil, vinegar, food coloring, a plastic cup, pipette or eye dropper, funnel, measuring cup, and spoon.


Why do this project?

This science project is a great one to do because it allows you to create your very own lava lamp using simple ingredients from your kitchen. You will learn about the chemical reaction between baking soda and vinegar, and the properties of water and oil that make them hard to mix.

Also Consider

1. Try using different types of oil (e.g., olive oil, coconut oil) and observe if it affects the lava lamp's behavior. 2. Experiment with varying amounts of baking soda and vinegar to see how it impacts the intensity and duration of the bubbling reaction.
