Details:
I've been experimenting with freezing soap bubbles for a while and it seems I have found a method and mixture which works the best up to now even in not really low temp. :) The mixture contains only water and Nivea for Men shower gel, nothing more added. The method is to hold the bubble upside down (hanging from the blower - so the weight of the bubble would result a thinner layer which would freeze more quickly.
The effect I noticed: when I blew the bubbles the moisture of my breath was trapped inside and holding the bubble against the sunlight it formed a small corona inside the bubbles! The corona slowly disappeared as the bubble and its interior became colder (the small amount of moisture must have condensed into the bubble's thin layer). The forms of the crystals which grew on the bubbles were also different with hanging bubbles.

Temperature was only -4 / -3,5°C (25/26`F)! Earlier experiments with more complicated mixtures never froze at such a relatively high temperature! This way the bubbles pop out quicker but it worths!
