On 12 March 2016, a video purportedly showing Walmart-brand drinking water turning into an indigestible gelatin-like substance after being poured out into a bowl went viral on Facebook: The video is real, but it doesn't capture water transforming into a strange gelatin substance — it simply shows water turning to ice. While water can freeze at temperatures as warm as 32°F, purified water can remain in a liquid state at temperatures below -40°F This supercooled water will instantly turn to ice when it is disturbed, due to a process known as nucleation: In July 2014, Live Science demonstrated how supercooled water instantly turns to ice when poured out of the bottle, replicating an experiment that can be done by just about anyone with a freezer, some purified water, and a couple of hours: This viral Facebook video does not demonstrate any flaws related to Walmart-brand water, nor water transforming into a strange gelatin substance. This video shows supercooled water turning to ice, a phenomenon that can be replicated with any brand of purified water.
