How to freeze water in about half a second

turn over this your first form in ice wizardy 101 .

In the video up top , Grant ThompsonofThe King of Randomdemonstrates to transform water to internal-combustion engine in seconds flat , using bottled water , a freezer and some glassware .

This is an instance ofsupercooling – the procedure by which a very pure liquidity is chilled to a temperature just below its usual freeze point without in reality form the jump to its square country . Bottled body of water is perfect for this , peculiarly the variety that ’s been purified via inverse osmosis , a process that bare water of all its particulates . Particulates can behave as “ seed crystals , ” or “ nuclei , ” to which a liquid form on the leaflet of becoming solid can attach and crystalize around . In this video , a seeded player crystal is introduced in the manikin of a cube of already - frozen water supply . As soon as it ’s introduced , the liquid phase apace crystallize and attach to the solid one , kicking off a mountain range reaction of ice - formation .

The bottle - flick is a short trickier . If I had to venture , I ’d say tapping the water bottle leads to a fugitive spike heel in pressing . Because H2O solidifies more easily at higher pressure , the motion picture causes a seed crystal to spring , which in twist trip a shower of internal-combustion engine - formation . [ Ed . bank note : Wow , am I ashamed . It is true that , by and large talk , solid phase are more dim than melted ones , and that increasing pressure therefore raises the freezing point . pee , however , is a notable elision to this principle , in that its unanimous phase is actually less dense than its melted one . This is why ice float in liquid water system , why fish at the bottom of lake ( where pressure is higher ) do n’t get freeze square in the dead of winter , and why a fugitive spike in pressure level would most unquestionably not coax the pee into solid variety . On the reverse , increasing the pressure in the feeding bottle would in reality work to keep the water in its fluent stage . This is gen chem , folk . I blame my temporary genial reverting on a lack of coffee berry . So again , I implore any forcible chemist out there to librate in : what ’s going on here ? ? ? So far , I like the solvent drift by Improbable , who stake that “ it may be crystalise due to tiny bubbles of air being created . ” ] ( Though I theorize this could just as easily be achieved by really squeeze the bottle . Any physicists or chemists care to weigh in ? )

Water that freezes as it ’s being poured out of the nursing bottle also solidify upon exposure to a seed crystal , which , in this case , is an already - frozen surface . This is similar to the effect observed whenfreezing rain , supercooled by its flightpath through sub - freezing layers of atmosphere , come into contact with an object cooled to a temperature below freezing . The result is aphenomenon screw as glaze - ice , which – if you live somewhere cold – you may have seen before , coating the spindly extremities of tree limb .
