The Science Siblings, Adam and Paige Jacobson, recruited 4-year-old Tukker and 2-year-old Jayger for a density experiment. They tested whether fruits and veggies float or sink in a bowl of water.

At cold temperatures, water has two different liquid phases, which become one at the critical point. The discovery could help explain water’s quirks.

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 ...

In this BASF Science Club experiment, we measure the same volume of 6 household liquids and then add a few small items to test their densities. This creates an awesome visualization!

Researchers at Stockholm University have captured the first direct experimental evidence of a long-sought second critical ...
