... Watching snowflakes grow ...
| If you can make snowflakes in the lab,
then you can make time-lapse movies of them growing. It turns out to be fairly
difficult (much harder than still pictures), so for now I only have a few. But I'm
building some improved hardware, so check back later for more movies.
Click the image (0.8 MByte) to see a time-lapse movie of a growing snow
crystal that was cycled back and forth between roughly -15 C and -12 C. Sectored
plates grew slowly at -12 C, while at -15 C dendritic arms spouted quickly from the tips
of the plates. The total elapsed time for the movie is 70 minutes.

click on the last image at right for a larger version of the same movie (3 Mbyte).
The larger movie may take a while to download.
