What You Need:
1 1-Pt (16 Fl. Oz.) Light Corn Syrup
2 1-oz. Bottles Red Food Coloring
Paper Towels or Newspaper
Container Larger than 1 pt. (I used two plastic cups)
Fork or Spoon (plastic works fine)
What To Do:
Lay out the paper towels or newspaper under your work area (food coloring can stain counter tops)
Pour all of the Corn Syrup into your larger container
Add both bottles of Red Food Coloring (the food coloring will sit on the top, separated from the corn syrup)
Stir with fork/spoon (when you first start stirring, it will be watery because of the food coloring; you'll know it's ready because it will have a thick, gooey consistency, more like the corn syrup)
That's it!
If you can let the blood sit overnight, it looks better and has an even better consistency, because it 'congeals' a little.
It also dries looking like droplets of blood; if you drip some on your neck (arm, face, etc) and let it dry (cool hair dryer works well), it will dry in a 'drip' shape, so that it always looks fresh!
Enjoy!
