The Lava Lamp Experiment

6개월 전

As part of our science lessons for our homeschool, we are trying out all kinds of really neat science experiments and activities. This lava lamp experiment tops the list!

Both of my kids had a blast with this. We’ve actually done it several times and with all different colors, but it never ceases to amaze them. It’s almost shocking how long they will engage with it.


The water and oil do not mix and the oil doesn’t change color because the food coloring is water-soluble. The Alka Seltzer reacts with the water to make bubbles of carbon dioxide. The bubbles attach themselves to the blobs of colored water and bring them to the top of the glass. When the bubbles pop the blobs of colored water fall back to the bottom of the glass.

This lava science experiment is sure to WOW your kids. They may even ask you to do it over and over again like mine did!
