Here’s another trick that would relate to Chemistry! What would happen if a super cold water gets in contact with a “not-so-cold” surface?
Right then and there! Just like that!
The scientific reason behind this phenomenon is a process called ‘supercooling’ and it occurs when a liquid has reached a temperature lower than its natural freezing point, but has not yet become totally solid
Once the supercooled liquid interacts with something that is at a low temperature (like the moisture on this man’s lips), a rapid chain reaction of freezing is put into action. While this process seems complicated, it’s easy to replicate at home. All you have to do is leave some water bottles undisturbed in the freezer for a couple of hours.According to Science Daily,
Supercooled liquid water must become ice at minus 48 C (minus 55 F) not just because of the extreme cold, but because the molecular structure of water changes physically to form tetrahedron shapes, with each water molecule loosely bonded to four others.

The findings suggest this structural change from liquid to “intermediate ice” explains the mystery of “what determines the temperature at which water is going to freeze.”
This intermediate ice has a structure between the full structure of ice and the structure of the liquid,” she adds. “We’re solving a very old puzzle of what is going on in deeply supercooled water,” says Molinero, an assistant professor at the University of Utah.
