Hollywood Gunshot Blood Effect!

Step 2 Fake blood for the effect.

Take a teaspoon or two of Arrowroot which you can find in health food stores. Heat a small pot of water and add the Arrowroot. Stir continuously until the mixture becomes thicker. Add a small amount of red children's non-toxic paint and stir in. The mixture should now be bright red. Add a tiny amount of red food coloring until you get the color right. Store in a bottle and thin it out by adding water to make the blood the required consistency for when you need it. For bullet hits you need to thin the blood quite a bit to allow it to spray out.
