LAVA LAMP EXPERIMENT DOWNLOAD!
Fourth Grade Science Science projects: Homemade Lava Lamp a plastic soda bottle from a recycling bin (just wash it out before beginning the experiment). Learn how to make a lava lamp without Alka Seltzer! It's a fun science experiment to do with your children. Have you ever wanted to know how. This experiment uses the density differences of water and oil to make what looks like a lava lamp.

We liked watching the water layer sink to the bottom, but we had to wait a while for the bubbles to disappear for the next step. Adding the water first, then the food lava lamp experiment, and finally the oil wasn't quite as fun, but it was a bit faster.
Add several drops of food coloring. If you did the oil first, then the water, it'll take a little while for the drops of food coloring to "break through" and tint the water. The oil floats on lava lamp experiment 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 lava lamp experiment dissolve.
As it dissolves it makes gas, carbon dioxide. Gas or air, is lighter than water so it floats to the top.
This creates the bubbles you see within the colored fluid in the soda bottle. Research Questions What happens when you add water to the plastic bottle?

Why do you think this occurs? What happens when you add the food coloring to the bottle?

What happens when you add lava lamp experiment Alka-Seltzer to the bottle? What experiments did you perform on the closed soda bottle twisting, shaking, etc. What did you notice during lava lamp experiment trial? As a consequence, the water sinks to the bottom of the bottle and the oil sits on top of it without mixing.
Food coloring allows you to view this separation more easily. This reaction will generate carbon dioxide bubbles that float to the top and escape through the open lid.
