Thanks. [endtext]

Here, high voltage was used to create thin ice needles, and stellar snowflakes subsequently grew on the ends of the needles. [endtext]

Now Libbrecht, widely known as the snowflake guru, has shed some light on a grand puzzle in snowflake science: why the canonical, six-armed "stellar" snowflakes wind up so thin and flat.

Let's say the line length section of the perimeter is shrinking at a rate of 1 pixel per second toward the nearest perimeter section, then that makes the next nearest crystal grow in perimeter at a rate of 2 pixels per second.
