This site, ‘Fake Snow’: Videos In Multiple States Show Strange Snow That Doesn’t Melt Normal, Burns, Smells of ‘Plastic’, shows several videos and images of people burning snow they collect from outside after recent snowfall. They claim that it chars and smells like plastic rather than melting like normal ice would. They cite this as evidence for some sort of weather manipulation conspiracy.
Is this (chemical phenomenon, not necessarily a conspiracy) really happening? And if it is, does it actually indicate anything unusual, or is it just people making assumptions?
