Procedure: 1. Preparation of animal blood serum: a. Slit animal's throat by jugular vein. Hang up-side down to drain. b. Place coagulated (lumpy) blood in a cloth or on a screen and catch the red fluid (serum) which drains through. c. Store in cool dry place if possible. CAUTION: Do not get aged animal blood or the serum into a open cut. This can cause infections. 2. Pour blood serum into jar, bottle, or other container and add gasoline. 3. Add the salt (or other additive) to the mixture and stir until a gel forms.
