Try This Amazing Lava Lamp Experiment With Your Child Today At Home!

Science as a subject is fun and interesting to learn! Unraveling the concepts of the universe, living and non-living beings, compounds, elements, nature, etc. can captivate anyone, in particular, growing kids. Science gets more exciting when it is experimented with and tested. Therefore, it is essential to let your children experiment with things around them to develop an early interest in Science. 

A plethora of amazing science experiments for kids is available online and in science textbooks which guides children with easy science experiments. One such experiment is the lava lamp experiment! The name itself sounds cool but the result of this experiment turns out to be much cooler! Here, we will provide you with simple instructions on how to conduct the lava lamp experiment at home with your child.

Lava Lamp Experiment- Materials Required 

Only a few simple items are required for the lava lamp experiment, which are easily available at home or at any store. 

Primarily you need water and vegetable oil to conduct the experiment. Along with this, other essential materials required for the lava lamp experiment are food coloring and Alka Seltzer tablets.

Steps To Set-Up The Lava Lamp Experiment


Step 1- Take a container and fill it with water. Add some food coloring to it, particularly orange to make it look like lava.

Step 2- Take a small cup and break open Alka-Seltzer tablets in them into two-three pieces.

Step 3- Fill vegetable oil in another container (about 3/4thh of vegetable oil). Pour the colored water mixture into this container and until the container is almost full and leave out 1-2 inches of space on the top. Add the Alka- Seltzer tablet to this mixture of colored water and vegetable oil. Observe the lava effect that fizzes from the bottom of the container with your child!

Step 4- Don’t overflow the container as it can get messy and make sure you are very cautious when your child is around the experiment set-up.

Conduct An Interactive Session With Your Kid After The Completion Of The Lava Lamp Experiment

You can make the lava lamp experiment more interesting by conducting a round of question and answer sessions with your child.

You can ask these questions mentioned below:

  • What did you observe from the lava lamp experiment?
  • What do you think happened to the oil and colored water mixture after the Alka-Seltzer tablets were added to them?
  • Did you learn anything new from the lava lamp experiment?

Science Behind The Lava Lamp Experiment

Water and vegetable oil do not mix, therefore only the water changes the color and not the oil. When Alka-Seltzer tablets are added to the vegetable oil and water mixture, the tablets react with the water and form carbon dioxide bubbles. 

Colored blobs can be observed at the top of the container as they are combined with the carbon dioxide bubbles, which push the colored blobs to the top of the container. The colored blobs recede to the bottom of the container when the carbon dioxide bubbles are popped.
