Each week, we bring you a quick and easy experiment you can do at home to explore a concept in science. This week, we look at ...

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 ...

Science Minute: Using density to layer liquids Science Guy Steve Spangler explains how you can layer liquids in this easy experiment that explores density.
