Version 1: Non-staining, Washable Blood

If you want to have any sort of convincing blood, you're going to need fake blood all over your clothes. Furthermore, if you care at all about those clothes, then you will want to return them to their non-bloodied state the next day. While this blood doesn't look very real on its own, it's incredibly simple and the point is to put it on your clothes where it will eventually dry and look great. Not all tempera paint is washable, so be sure to get the washable kind!

Ingredients:

• Washable red tempera paint
• Washable blue tempera paint
• Washable brown tempera paint (optional)
• Water

Instructions:

1. Not all tempera paint is washable, so make sure you get the washable kind! Yes, it's important enough to repeat!
2. Pour about 2-4 Tables spoons of red paint into a bowl or container that you think you will need.
3. Add about ¼ as much water as you did red paint, and mix. You want the blood to flow but not be so runny that it looks unrealistic.
4. Slowly add blue and/or brown paint a little bit at a time, and mix. Again, you can always add more, but you can't undo once the blood is too dark!
5. You're finished!

Version 2: Simple, Edible Blood

There isn't much to the taste in this recipe for fake blood since it's mostly just sugar, but it's super easy to make and looks fairly convincing as real blood. 

Ingredients:

• 1 tablespoon cornstarch or flour
• 1 cup white corn syrup
• Chocolate syrup to achieve desired dark color
• ¼ cup water to achieve desired thickness
• Several drops red food coloring

Instructions:

1. First, add the cornstarch or flour to a bowl and make sure to break up any clumps. You will thank yourself for doing this now because it is easy for clumps to form after you add the liquids and it's very challenging to get rid of them then. Use a flour sifter for best results.
2. Add the corn syrup, red food coloring, and half of the water. Mix until dissolved.
3. Add the chocolate syrup slowly to achieve your desired final color. Remember: You can always add more, but you can't undo once the blood is too dark!
4. If needed, add a small amount of water to thin the blood.
5. You are finished! This one is not recommended for clothes because the red food coloring could stain the fabric
