Fascinating: “Real” Ice Contains Bubbles of Air Thousands of Years Old

“Real” Ice Contains Bubbles of Air Thousands of Years Old.

Read the full interview here.

Probably the most exciting thing about it is when you have real ice—that’s where the snow has been gradually compacted and eventually formed into ice, and the density has increased. When that happens, if the ice is old, it will often trap air bubbles in it. Those air bubbles can contain carbon dioxide from ten thousand years ago or even a hundred thousand years ago. And when you put an ice cube of that ice in a glass of water, it pops. It has natural effervescence as those gas bubbles escape. You get a little a puff of air into your nostrils if you have your nose over the glass. It’s not as though it necessarily smells like anything—but when you think about the fact that the last time that anything smelled that air was a hundred thousand years ago, that’s pretty interesting.
