NON-TOXIC BLOOD

Note: this recipe yields blood that is very sticky initially, especially in hair. It is good for uses that involve children and possible ingestion, as it's not toxic.

1. Combine 1 part water with 3 parts corn syrup (known as golden syrup in the UK).
2.  Add drops red food coloring gradually and mix gently by stirring. Continue adding drops until the shade resembles that of real blood (always err on the side of adding less, as it's easier to add more). Add a small amount of blue or green food coloring to achieve a more realistic shade. 
3. Add a thickener. Suitable thickeners include:

•  Dry thickener - Add sifted flour or corn starch to your mixture, and gently mix it all again. You may get small lumps forming at the top of the mixture. Wait about a minute and the lumps will float to the top where you can remove them easily.( You can also use glycerin.)
• Wet thickener - Stir in chocolate syrup until the desired consistency is reached. Chocolate syrup adds a realistic brown tone to the blood.

    4. Let the mixture sit for ten minutes in a warm environment.This will give it   
        some time to thicken.
