Lava Lamp Experiment
A Lava lamp is based on two important scientific principles: Density and Polarity.
This is a perfect example of oil and water NOT mixing due to these scientific concepts.
Understand the working principle of a lava lamp clearly by performing the experiment given here.
Materials for Lava Lamp Experiment
- 2 Small Plastic Bottles with Lids
- Food Coloring in 2 colors
- Vegetable Oil
- Antacid Fizzing Tablets
- 2 Small Pipettes
- 2 Small Dishes
- Water (not supplied)
- Fill the Bottle 3/4 full of oil.
- Fill the small bowl with water.
- Add several drops of food coloring into the water.
- Pour the colored water on top of the oil (almost to the top).
- Now, wait for a few minutes until the water and oil separate.
- You can see that the colored water and oil do not mix.
- Break the antacid tablet into a few smaller pieces and drop only one piece in the bottle.
- The materials will begin reacting and appear like a lava lamp.
- Whenever required, drop another piece of the tablet to make a new flow of bubbles.
Note: This can be messy so make sure to have paper towels and a water/oil proof surface.
This is a very fun experiment for all ages!
Can be done over and over with more antacid fizzing tablets.
