DIY Lava Lamp
One of our favorite experiments to date is this easy DIY Lava Lamp that you can make with your kiddos using just 4 simple ingredients. We are sure this experiment will leave you and your kiddos pleasantly surprised!
- 2 Tbsp Baking Soda
- Baby Oil or Cooking Oil (enough to fill Jar)
- 2 Tbsp Vinegar
- Food Colouring
- Flashlight App on Smart Phone
Start by adding the baking soda to the jar, then fill the jar with oil. Once the jar is full, mix a few drops of food coloring and a couple tablespoons of vinegar in a small bowl. Pour the mixture into the jar. Quickly turn on the flashlight app on your phone and turn it face down, place the jar on top. Watch this cool chemical reaction take place. The chemical reaction will last approximately 15 minutes.
How Does It Work?
You may be wondering how does this work? What's the science behind this cool experiment? The baking soda and vinegar react to create CO2. You can actually see the CO2 if you look closely into the jar. They are small bubbles that have attached themselves to the vinegar. When the C02 surrounds the vinegar, it makes it lighter than the oil and lifts it to the top of the jar, but since CO2 is a gas it also tries to escape. When the CO2 escapes the vinegar falls, creating this beautiful movement in the jar. How Cool is that!
