Mercury Shouldn't Be Liquid. But It Is.
Mercury, a.k.a. quicksilver, is famous for being a liquid at room temperature...and also below room temperature. But you can't use a high school chem class to explain why. Instead, we need a little help from Einstein.

The Physics of Caramel: How To Make a Caramelized Sugar Cube
This video is about how the physics and chemistry of sugar (in particular, how it melts, and how it caramelizes) is more complicated than you might think. It involves fructose, sucrose, glucose, and a sticky mess. Credits: Gallium...

Why Is Ice Slippery?
Winter: It's that time of year when you're out for a stroll and maybe miss a hidden patch of ice and fall flat on your butt. Why you gotta play us this way, ice?

How Do Glaciers Move?
Glacier ice is weird. It's solid. Solid things aren't supposed to flow. But glacier ice flows like a liquid, and it does that without melting! How is this possible? I traveled to Mendenhall Glacier in Juneau, Alaska to find out.

Science of Glass Making: How is Glass Made?
Glass is made by heating sand (mostly composed of silicon dioxide) until it melts and turns into a liquid at a high temperature of around 1700° Celsius. When the molten sand is allowed to cool, it becomes an amorphous solid, featuring...
