[Phys-L] frozen bubbles

We are coming up on the season for frozen bubbles.
The temperature has to get down to near zero Fahrenheit, or below.
I don't fully understand why it has to be quite so cold, but evidently
it does.
In addition to the freezing-point depression there is some
supercooling / nucleation business going on.
In any case, they are interesting and pretty.
