There are some really easy home made blood recipes you can try.
Homemade Fake Blood
1 c. Karo Syrup
1 Tbsp Water
2 Tbsp Red Food Coloring
1 tsp Yellow Food Coloring
Mix together in a mixing bowl and you're done. Try adding blue or yellow for a different shade.
Simple Fake Blood
Clear Corn Syrup
Red Food Coloring
Milk - Optional
However much fake blood is how much corn syrup you'll need. Pour it into a bowl and mix in some red food coloring. Add some blue if you like. Adding a small amount of milk will make the blood appear darker and thicker.
Realistic Recipe
2/3 c. Corn Syrup
1/3 c. Warm Water
5 Tbsp Corn Starch
4 tsp red food coloring
1 Tbsp Powdered Cocoa
2 drops of green or yellow food coloring
Mix the corn starch with the water in a large mixing bowl. Stir in the corn syrup. Add the food coloring slowly, checking for color.
