(Newser) – The producers of the sick new thriller Contagion came up with a creepy way to promote their product. Warner Bros. Pictures Canada hired microbiologists to culture bacteria on two signs that grew to spell out the name of the movie in a most disgusting way, reports Adweek. Scientists inoculated two large Petri dishes with live bacteria—including penicillin, mold, and pigmented bacteria—then used them to "paint" the signs, which were displayed in the windows of an abandoned storefront in Toronto.
