COMSTOCK PARK, Mich. — Our science experiment this week deals with water, oil and food coloring to produce what appears to be fireworks in a glass. This week's demonstration was conducted at Pine ...

This experiment demonstrates how water at different temperatures has different densities, creating beautiful layering effects. You'll see how warm and cold water interact and learn about density ...

Create a colorful tower of liquids that stack on top of each other based on their densities. This experiment demonstrates how different liquids have different densities and why some liquids float ...

Charged surfaces in contact with liquids—such as biological cell walls or battery electrodes—attract oppositely charged ions from the liquid. This creates two distinct charged regions: the surface ...
