The spraying of 'chem-trails' is no longer a conspiracy theory.
There are published scientific articles in the fields and in government budgets..
1. It could be a hoax. Cut scene. The snow on the ground might not be the same as in the hand. The one in hand could be a mix of Styrofoam or other materials. Easy enough. White is white. Plus with deepfakes these days we should retain a bit of skepticism.
2. It could have natural basis. The snowball re-froze on the outside because it was cold. It is of porous nature because of conditions. The black marks are from the lighter as it is burning yellow and producing carbon.
3. The snowball composition could have been affected by chemicals in the air.
(but complete denial should never be automatic when there is missing information. Here is an example of: Admit water will burn due to chemicals within. Strongly deny that any of chemicals used in fracking were involved per highest scientific authority. Threaten results with legal fraud and any further conversation. Deny any other factors or combination of factors could be responsible)

methane gas occurs naturally in groundwater in sedimentary basins in Colorado and around the world, according to the Colorado Oil and Gas Conservation Commission (COGCC). Some towns like Burning Springs, West Virginia were given their name hundreds of years ago because water sources could be lit on fire due to naturally occurring methane bubbling up into their streams. According to researchers in Colorado, “[methane] also is found in large quantities in the basin from naturally occurring, biogenic sources.”
