Has anyone actually witnessed water flash-freezing before? Water bottle left half full in car on Saturday. Low of 14F overnight. Tipped liquid water to show my wife, "isn't this crazy it's not ... " <water flash freezes in other half of bottle> "what the fuck was that!?" I say and my wife look incredulous.
When I shifted the ice back to the other side of the bottle is was all slush and some water. So it wasn't all frozen, but enough to appear solid for a few seconds. Crazy.
