DIY Lava Lamp Experiment

Kids Corner

Have you ever done the volcano experiment? The one where you mix baking soda with lemon juice or vinegar and it goes BOOM!? Here’s the followup to that, in an experiment which is really fun and entertaining! You can do this with little kids. You can also pretend to be a wizard making a potion too. It is super simple and you probably already have most of the supplies.


You will need:

  • Water
  • Vegetable Oil
  • Food Coloring
  • Alka Sezler (or any other fizzy tablet)
  • A Bottle or Jar with a cap


Fill 1/3 of your Bottle/Jar with water and add the food coloring.

Very carefully pour the oil to the remaining 2/3 of the Bottle/Jar, making sure the colored water and the oil don’t mix.

Lava Lamp Experiment

Break the Alka Sezler or fizzy tablet and add it in, bit by bit. And…

now watch!

The more pieces of fizzy tablet you put in, the more bubbles you’ll have!

To explain a bit what is going on: oil is a denser than water, and that is why they don’t mix. And when you add the fizzy tablet to the water, the bubbles that it creates get trapped in the oil, giving the illusion of the lava lamp.

Do you want more fun and easy things to do with your younger siblings? You should also try making these super yummy Prison Bars!
