Alfred Hitchcock's 1960 film, 'Psycho' set the tone for modern horror as we know it. Because the film was shot in black and white, they were able to make some substitutions for dramatic effect. What interesting substance did they use to portray blood?

Chocolate syrup, specifically Bosco brand, was commonly used as stage blood in black and white films as it closely resembled the viscosity of real blood.
