Glowing Oil and Water Experiment

We all know that oil and water just don’t mix. But what happens when you make them glow, add kids, dim the lights, and fill their brains with words like “density” and “polarity”? Magic. That’s right—Pure. Magic. We love Crystal’s at Growing a Jeweled Rose play-by-play on this project, and the best part about it is how you can turn your oil and water experiment into a DIY lava lamp when you’re through.

The Science Lesson: Density and Polarity
An object’s density—or how tightly packed together its molecules or atoms are—is a predictor of whether it will float or sink. Water molecules are more dense than oil molecules, and will always sink below oil. Additionally, water and oil have different polarities—or charges. Since water has both a negative and a positive charge, water molecules will attract other water molecules.
