It is weather modification at its best. When are we going to stand up to these demons? They are killing us off by using this stuff. There is a snow sample floating around showing what is in our snow and actually how much is in it. Aluminum, Boron, Lithium, etc. A good person that can teach you is on youtube and his channels name is Mike Morales. He is amazing, I feel everyone needs to at least check himout. He is so much better than any weather channel. He actually teaches you while making his video.
