This morning it’s 8o F and we certainly have ice in Pittsburgh!
Did you ever think about how unusual and important it is that ice floats?
Watch the video above to learn how it happens.
Ice is way cool!

p.s. I’ve been waiting since November to write about ice. December was mostly ice-free and often quite warm. What a winter!
Interesting. Never thought about the implications for fish.
Yes, if ice didn’t float, then streams (or lakes) would freeze and the ice would sink, then freeze again, and sink again, and eventually the stream or lake would freeze solid, and in colder climates might never completely thaw again. 🙁
