I've lived in the far north of Canada, and worked in the Arctic. I can attest that most water doesn't freeze instantly, even at -60 F.

If you were to cool water to the freezing point, and hold it there until the latent heat of fusion dissipates — then, you could freeze water instantly.

OTOH, it is safe to make yellow snow — despite the tall tales that abound in the Arctic.

Conversation, OTOH, can be difficult. You have to pick the words up, carry them inside your cabin, and thaw them on the stove before you can hear them.
