Yes, there are dissolved minerals in the water, but the concentrations are very low. Adding salts can lower the melting point of ice, but only at much greater concentrations. Particles can initiate freezing, but there are no particles in this water that can nucleate ice.
It would freeze in you throat! Actually, it would probably warm up too quickly to freeze, but I wouldn't try it - it would just feel uncomfortably cold!
@bjm188 yes, I undestand that this water isn't tasty =). but it can be very interesting. Some experiment with not very cold water (-1 C) may be not dangerous for health but interesting.
@saga111a nothing happens. The specific melting (=freezing) heat of water is like 80 times more than its heat capacity. It means that the 8 deg overcooled water allows to melt only about 10% of the sample. You can actually see some dilute mixture of water and ice as a result. So it won't make your throat explode and nothing like that.
It's a chilled bath of a mix of ethylene glycol and water made by Haake. It's possible to do the same experiment with a standard kitchen freezer, but our chiller gives us much more control over temperature. If you go below about -10 C the water freezes in the bottle.
Hi skizm22, planes also get freezing supercooled water inside their fuel systems which can caise problems. Google planetearth+supercooled water+aircraft
Pilots have a problem with supercooled water in storm clouds...when it hits the airplane and its instruments used for guidance they freeze automatically and these new jets that are mainly automated...they have huge problems....sick video.
Hi locuk, if you dropped some dry ice into supercooled water the water would freeze. What do you mean by perpetual ice? Once supercooled water freezes it will only turn back into water when warmed back above 0 C.

Simple chemistry but nice video none the less.

@bjm188 "just pure mineral water straight from the shop" - doesn't the word "mineral" mean that there are salts or other impurities in this water?

What device do you use for supercooling the water?

same way freezing rain forms... supercooled water hitting a surface and becoming ice

I wouldn't try it! It would be very unpleasant.

This would be dangerous to drink then, straight from the bottle?

@Baraquiel, that is water. Plain, purified water. That's the whole point.

If you dropped dry ice into supercooled water, would the water freeze around the dry ice creating perpetual ice?

Cool trick. Tried it after seeing you in uni but didnt work for me :) I looked stupid pouring water on a plate and nothing happening haha
