Why does water flow twist my shower hose?
I have a showerhead with a flexible, 5 foot hose. I don't know if this matters, but the flexible hose is made of metal rings. When you yank on it, it stretches a little (there's probably some elastic inside) and the rings move a bit further apart. It's a very common design that you will find if you search for "flexible shower hose" online.

Normally the showerhead sits in a bracket on the wall, with the hose hanging in a long U shape. The twist on the hose is about 1/4 turn.

When I turn on the water, the hose suddenly coils up, to about 2.5-3.5 turns. If I try to untwist it, it resists. When I turn off the water, the resistance disappears and the hose untwists.

Why would water through a hose twist it?
