After I played it through, a bunch of other videos came up. One guy used what looked like a Buck Rogers ray gun. Another had what looked like an industrial smoke generator. In both, the guys speaking foreign languages generated huge clouds of smoke-like stuff that blew back all over them. If it was OA, they would be dead for sure, buut they just continued talking as they demonstrated application to bee hives. No respirators, no coughing -- nothing. Very strange and frightening what these could inspire somebody to do.
