There has been a lot of information and videos posted about Snow in the U.s turning black when a lighter is put to the snow. When the snow was put to a lit lighter, it turned black and nearly didn't lose any volume, similar to not melting, as well as giving off a smell similar to burning plastic [Unpleasant]. The response has been widely spread as the result of chem trails being sprayed in our sky. Is this a man made affect or is this a natural occurrence in which the snow is reacting to the lighter's butane? Or is it something different altogether?
