Oil and Water

We did a science experiment today. We poured water into two bottles, then poured some oil into both. Nadia was surprised that oil and water did not mix. You can see the oil floating on top.

I started explaining about polarity…however left it at that. She now knows that it’s due to polarity which is a good start for her 🙂

Next we dropped some food coloring into both the bottles…blue and green.

They do make a pretty picture don’t they?

Nadia enjoyed shaking the bottles and watching the molecules separate back…she was quite fascinated. They remind me a bit of lava lamps.

Do share a line about your favorite science experiment.
