Photographer Tom Falconer creates and captures images of frozen bubbles. Goli Mohammed of Make interviewed Falconer and asked him how he does it:
For frozen bubbles I usually wait until it is (at the warmest) 10 below freezing (22 F) and even at that temp they will take a few minutes to freeze. Again it needs to be extremely calm, because you'll need to blow the bubble then catch it on the wand or some kind of wet surface and wait for it to freeze. As it freezes the thick swirls in the bubble will stop moving, and little fingers of ice crystals will creep across the surface. They don't freeze into something that will shatter, they tend to be somewhat rubbery and will eventually collapse on itself.
