1/2 bottle of light corn syrup
very hot water
squirt of liquid soap
red food coloring
blue or green food coloring
Pour light corn syrup into a bowl and add hot water sparingly, adding and stirring until you have the right consistency. Add a squirt of liquid soap to make it the blood easy to clean off later. Tint with red food coloring. You may add a drop of blue or green if you like to make the blood a darker color. Store in the refrigerator until ready to use
