Ingredients:

1 pint of clear corn syrup
100 drops red food coloring
1/4 cup of water
1/4 cup sifted flour or corn starch
8 drops blue food coloring

First remove about a 1/4 cup of the corn syup, and replace it with an equal amount of water. Add the food colouring and mix the blood by gently shaking.

Now add the sifted flour (or corn starch) to your mixture, and gently mix it all again. If you use flour, you may get small lumps forming at the top of the mixture, if you do, then wait about a minute and they will float to the top where you can remove them.

You now have a bottle of realistic fake blood! You can experiment with the amounts of ingedients which you feel gets you the best "blood like" consistancy.

You must be aware that this mixture may temorarily stain skin, and may permanently stain clothes. Because of the use of natural sugar in the corn syrup, this fake blood will not keep long. You can extend its shelf life by simply storing the blood in a refrigerator.
