Ben Nye's Mass Casualty Blood Powder gives you heaps of
hemoglobin in a hurry. Trusted by artists in film and television as well
as professionals in training simulations, one jar of Mass Casualty
Blood Powder converts into a gallon of regular consistency, freshly
exposed blood. Simply mix with water.
The versatile formula can be thinned or thickened by using more or
less water, or by substituting water with corn syrup. Washes from most
fabrics and surfaces, though spot testing is suggested before use.
