Mercury Shouldn't Be Liquid. But It Is.

12th - Higher Ed
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.

How Do Glaciers Move?

12th - Higher Ed
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.
