Every skier knows that natural snow is better than man-made snow. But there will be plenty of both at the Winter Olympics. So what is the difference? And how is snow made? Those questions are answered in the following videos.

How to Make Snow (If You’re Not Elsa) is a short video produced by SciShow that explains how snow is made at ski resorts by using cooled water and compressed air.

Reactions, a YouTube channel that produces lots of science videos, has a short video that explains how snowflakes are naturally created.

The National Science Foundation has a neat video that explains how high speed cameras capture images of snowflakes forming. The video then goes on to explain why some snow is light and fluffy while other snow feels wet and heavy. (Jump to the 4:25 mark to get to the section about the formation of snowflakes).
