Purified water will 'instantly freeze' under certain conditions, and you can even make it happen at home. Is it magic? No. It's science!
Boyle's Law describes the relationship between pressure and the volume of a container with gas in it. As the volume of the container decreases, the pressure inside the container increases.
A research team has found that water acts strangely on an air-drying towel, which contributes to its signature stiffness.

Entropy is the disorder of a system, but that means a lot more than making a mess of a room.
Weight is the measurement of gravity's pull on an object. And it varies by location. Mass is a different beast altogether.

Researchers have come up with the most precise determination of Planck's constant ever, making it possible to reframe the idea of what a kilogram even is.
Stanford University researchers for have for the first time observed the formation of a super-dense frozen water crystals called ice VII, which don't naturally exist on Earth.
Science is still working out exactly what makes frozen water so slippery, but there are a few intriguing theories.

For nearly 40 years, science has relied upon the Standard Model of particle physics to describe the universe. But now some are saying that it's time for a rewrite.
Atoms: the building blocks of life and the universe. We're all made of these microscopic bits of matter, but how many does it take to make a complete human being? And exactly what kinds of atoms do we have inside us?
Wavelengths are used to measure the size of a wave. Learn about wavelengths in this article.
An atom is made up of neutrons, protons and electrons, and its atomic number is calculated by adding up the number of protons and neutrons in the atom's nucleus. Learn about the basic structure and the atomic number of an atom in this article.
