The salt water might never freeze completely. By saturating the water at 32°F (0°C), the freezing point can be reduced as low as -6° F (-21.1°C), which is slightly below the average air temperature in most personal refrigerator-freezers.

Why do your hands get so warm so quickly after being freezing cold without a outside temperature change?
It is probably due to the subjective sensation of hot and cold that you feel. I'm not basing this on personal MEDICAL QUALIFICATIONS BUT EXPERIENCE IN A COLD CLIMATE. TRY EXPERIMENTING WITH A BOWL OF WARM WATER (BLOOD HEAT) AND A BOWL OF ICE WATER. Chill your hand then plunge it into the warm... do the opposite.. test and learn. Firstmate.

I once saw a video with a person throwing hot water into very cold air it instantly froze how come it does not work with cold water?
In fact hot water freezes quicker in a cold climate, because of the sudden temperature change. If you want to test it for yourself, take two ice trays, fill one with cold water and one with very hot water, stick them in the freezer, and see that the hot water freezes quicker.
