Ben Nye Blood Powder gives you large quantities of fake blood quickly, and especially good when space is tight. Used by special FX artists in film and television as well as professionals such as medical doctors or military doctors in training & simulations. One 3oz Mass Casualty Powder jar converts into a 1 gallon / 4.5 litres of regular consistency realistic blood. More can be made by adding more water creating thinner blood and vice versa. Simply mix with water. The versatile formula can be thinned or thickened by using more or less water. You can also substitute water with corn syrup or mixing liquid. Washes from most fabrics and surfaces, though spot testing is highly recommended before use. Made in the USA.
