ELI5. running water doesn’t freeze

Question

I know water freezes at 32F (0C). But it can be colder than that and not freeze, but the water is moving. Why is that? Friction of water molecules?

Answer 1

Running water can freeze, it is just more difficult to freeze, water turning to ice is basically water molecules grabbing onto the ones next to them and “locking arms” with them if the other molecule is moving rapidly it is difficult to lock onto it.
