Every one of these I saw is stupid. They’d hold the snowball right up to touching the wick of a candle, which would obviously create an area of poor and incomplete oxidation resulting in tar deposition, and they’d say the snow was “turning black”. No shit, dummy, you’re getting tar on it!

Put one of those snowballs in a pan and heat it up on the stove. You won't even have to put the heat up very high. I guaran-fucking-ty it will melt into liquid water and not have any chemical smells to it. It might be a little dirty perhaps, but you could safely consume that melt water. They never try to melt it normally or even just let it sit and melt on its own. Lying fucks trying to promote fear and disinformation. They're probably jews.

There are a lot of disinformation conspiracies showing up. The most obvious was flat earth, but there are more "convincing" ones making rounds. Just remain skeptical and look before you leap.
