Do you even science???? all these ppl posting videos saying that the government is spraying shit in the air and the chemtrails is some mystical substance. Bullshit, bullshit, Buuuullshit! So, everyone knows that the 3 most familiar states of matter are gas, liquid, and solid. Typically, to transition from a solid to a gas, the solid must melt into a liquid, and then vaporize into a gas. However, there is another phase transition known as sublimation that takes a solid directly to a gas. (think: dry ice) Regular snow can sublimate below the freezing point under certain pressure conditions. This typically happens with cold, dry air, like what is found during the winter. Because this winter has been much drier than previous years for the East coast, sublimation is achieved more easily. Though a snowball may seem like a dense unit, it is still just a collection of particles with a high amount of surface area. When these particles come in contact with a much higher heat source (like a blow torch or a lighter) it energetically favorable to just sublimate directly into vapor. So, what about the black marks left on the snow? Thats just residue from the lighter/blowtorch/match, as the fuel did not burn cleanly and completely
