Build-your-own snowflake

In snowy climes, people passively watch snowflakes fall. But in balmy Pasadena, California, Caltech professor Kenneth Libbrecht and his friends build their own snowflakes. Click on the image to see one of their many movies showing one growing. Here’s our quasi-poetical tribute to them:

snowflake-movieTwinkle, twinkle, little flake,
Bestest thing that I can make.
Most folks don’t do much at all,
Just watch snowflakes as they fall.
Hey! They could make snowflakes, too!
I would tell them what to do.
