Fake blood becomes a costume option.
The hyper-realistic fake blood we think of from movies like “The Shining” came about in the 1960s, invented by pharmacist John Tinegate. Nicknamed Kensington Gore, it launched re-formulations of fake blood that would appease audiences of horror movies in color. Today, most fake blood (including the kind you might buy from the Halloween store) is made with corn syrup.
