Happy Halloween

There is a positively wonderful scene in Ghostbusters 2 where evil energy in the form of a gooey pink liquid seeps out of the sewer-cracks in New York City, and whatever it touches becomes possessed. A woman in a large mink coat accidentally steps in it and, behold, her coat comes back to life to seek vengeance. This leaves me with only one question...where can I get some of that evil pink liquid to throw instead of red paint?
