I was just thinking...you know it would be a great crime to kill someone using bubble-wrap, and I don't mean by wrapping it around their faces so they suffocate. I'm not entirely sure how bubble-wrap is produced, but it involves bubbles filled with a gas, probably regular old air. But what if someone filled those little bubbles with some deadly spore or gas, used them as packing material for something, and mailed it to the intended victim? You know the poor person wouldn't be able to resist the joys of popping the little bubbles and unknowingly causing his own death.
Man, if I weren't an evil genius I'd be conspriracy theorist genius.
