After supercooling, water turns instantly into ice when poured into a metal water bottle.<br /><br />Footage filmed on July 21 shows water, which was supercooled overnight, turning into ice as it is being poured into a bottle. <br /><br />One Reddit user explained the process: "Water won't freeze without a nucleation point to start the crystal formation. <br /><br />"So you take pure water in a clean container, cool it to below 0 degrees Celsius and then agitate it in some way. <br /><br />"Shaking it is a common way to do it as you get to see the water quickly turns from a liquid to a solid."
