The Crazy Russian Hacker has another “science experiment” in which he shows us how to use steel wool to set the world on fire, or just make pretty sparkles, while warning us over and over not to try this at home.
He does this with steel wool, a string, and a 9-volt battery. That’s all. How can something so simple be so dangerous? Surely, now that we know how easy it is, no one will dare try this at home. After all, safety is numbern perty. -via Viral Viral Videos
