My great-great aunt was the mistress of a magician who performed the Cassandra Propaganda back in the 1800's, and I urge everyone to stay away. They don't know what they're dealing with, or how to protect you. If anything, people should be figuring out how to shut it down.
I've got some old newspaper clippings back at home that tell all about the "Carnage in Kalamazoo," which I will dig up. They didn't know if it was an earthquake or a thunderstorm or a hurricane, but the eyewitness accounts are chilling - especially the part about the "Snow-men" that wreaked havoc and death on the people of Kalamazoo.
Whatever it takes, @Hormiga Man
and the Cassandra Propaganda should be stopped. Aren't there licenses or permits you need to do this kind of magical experiment? The school is completely neglecting its responsibility in not controlling this.
