A soap bubble is a layer of water molecules sandwiched btwn two layers of soap molecules. It begins freezing at its coldest point, but the fluid inner layer shears off ice crystals & swirls them about, until they finally interlock

That swirling snow globe effect depends on critical differences in temperature and surface tension, though. It's not a given. Sometimes the freezing happens more cohesively, as feathers of ice growing from bottom to top

Lori Grimmett has captured some wonderful close-up footage of the swirling inner layer of a freezing soap bubble, showing how crystals tend to form wherever the bubble rests against a cold surface, before potentially breaking away like fractal icebergs
Apparently it is also possible for soap bubbles to freeze MID-AIR

Frozen bubbles weave intricate designs from water and air. They make the ethereal solid, the transparent gorgeously opaque. They are fragile yet resolute, ephemeral and timeless all at once.

I mean, just look at this. The ensorcelling geometry of ice. The sheer beauty of this world. That such a marvel might exist, if only for a moment.
