What is a good hypothesis for a lava lamp? Hypothesis:We think that adding oil, water, and food coloring together will make a lava lamp effect because we alredy know that water and oil separate because of their complete density contrast. The alka-seltzer will make it have a lava lamp effect.

How does a lava lamp work science fair project?
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.

Why does the lava lamp experiment work?
How it Works: The oil floats on top of the water because it is less dense or lighter than water. The food coloring has the same density as the water so it sink through the oil and mixes with the water. When you add the tablet it sinks to the bottom then starts to dissolve.
