From The New York Times, Olympics 2014: The Science of Snowmaking

Machines make snow the same way nature does, by freezing water droplets. But they do it a few feet above the ground, rather than in the much colder conditions high in the atmosphere. Snowmaking machines employ a few thermodynamic tricks to help, but at times there is a limit to what physics can do…

…a droplet may not freeze entirely during the few seconds it takes to fall to the ground — what snowmakers call hang time.

“We’re basically making eggs,” Mr. Moulton said — icy shells around still-liquid centers.

Filmed by Enrico Sacchetti from a helicopter near the Mario Zucchelli Research Station at Terra Nova Bay, Antarctica, this soaring journey over mountainous white landscapes really reveals both the majestic scale and rugged details of The Seventh Continent.

In the archives, more videos about Antarctica, including a look at what’s beneath the world’s largest ice sheet and traveling back 800,000 years with Antarctic ice cores.
