>Who inhales the dust, gets a cramp and dies. Do not open the windows, cover it completely with black paper. All open-standing water become poisonous and also all open-standing meals, which are not in locked doses. Also no meals in glasses, because they would not cover it up completely. Outside the death by dust goes around, many humans die.

Let's asume it's true. What could that dust be? From the perspective of someone who lived roughly 70 years ago, "glasses" could very well mean plastic (food) containers.
