Lava Lamp Experiment (Chemistry)

This simple chemistry experiment uses the density differences of water and oil to make what looks like a lava lamp.

▶️ How to do the lava lamp science experiment:
Step 1: Fill a wine glass 1/4 full with water.
Step 2: Add several drops of food coloring.
Step 3: Fill the rest of the glass to the very top with mineral oil (vegetable oil will work as well, but has a yellow tint).
Step 4: Drop a small piece of an Alka-seltzer tablet into the glass, and observe the reaction.
▶️ How the lava lamp experiment works:
You'll notice that some of the colored water from the bottom traveling up through the mineral oil, just to fall right back down again. This is due to the sodium bicarbonate in the Alka-seltzer, which creates carbon dioxide bubbles. These bubbles carry some of the water up through the mineral oil to the top. When the bubbles pop, the water sinks back down to the bottom since it is denser than the oil.
Notice how the water sinks faster or slower depending on how many carbon dioxide bubbles are still attached.

Is the reaction from alkaseltzer safe for kids? Just curious as I want to experiment

[@kiminoyawa8922]

what is the chemical reaction type of lava lamp?

Is this fermanently for ever?

What mineral oil you used

[@BeardedScienceGuy]

The type is not really important. I chose grocery store "Mineral Oil" instead of vegetable oil just to avoid a yellow tint to the oil.
