What is the science behind lava lamp?
When enough bubbles pop, the water-and-remaining gas becomes more dense than the oil. So the ball of water sinks down through the oil and joins the rest of the water. Changes in density as gas is added to or taken away from water cause it to float up and sink down through the oil. Thus the lava lamp is created!
Why does the lava lamp experiment work?
