How to Make Fake Blood

If you're going for the cool look this Halloween, nothing adds special effects like realistic-looking blood. There are many ways to concoct it, ranging from edible blood made from kitchen ingredients (especially useful for kids, and when going for the "bleeding from the mouth" look) to chemically mixed, chillingly realistic blood used on movie sets. Whatever your preference, here's how to put it together.

Edit Steps

Non-toxic blood

1. Note: this recipe yields blood that is very sticky initially. It is good for uses that involve children and possible ingestion, as it's not toxic.
2. Combine 1 part water with 3 parts corn syrup (known as golden syrup in the UK).
3. 

   Add drops red food coloring gradually and mix gently by stirring.
   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.
4. 

   Add a thickener.
   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.
   • Alternate Wet Thickener - You can also use pancake syrup to also add a brown tone, and make the blood a bit more thick, not too less and not too much.
5. Let the mixture sit for ten minutes in a warm environment. This will give it some time to thicken. And then you can freak people out with it – it's a lot of fun.

Chocolate blood (edible)

1. This mixture looks great, smells great, and tastes like chocolate!
2. Combine light corn syrup with red food dye until you get a shade that closely resembles real blood. You can also use a red drink mix (like cherry Kool Aid® powder) instead of red food dye, although be warned that this changes the flavor.
3. Carefully add a small amount of cocoa powder to the syrup mixture to darken the shade and cause the fake blood to turn opaque like real blood.
4. 

   Perfect the consistency.
   Perfect the consistency. Either:
   • Thin the blood by slowly adding water; or
   • Thicken it with a couple pinches of flour or cornstarch mixed in carefully and slowly.

Icing blood (edible)

1. Put a small amount of icing sugar in a bowl.
2. Add a few drops red food coloring until frosting reaches the desired color.
3. If it's too thick, add a little water.

Jelly / Jell-O blood (edible)

1. Use for large wounds to simulate clotting. Splatter it on your walls for a Dexter Season premiere party.
2. Microwave 3 to 4 bottles of glycerin.
3. Add one cube of strawberry jelly or Jell-O and mix thoroughly.
4. Add 1/5 of a packet of gelatin.
5. Add red food coloring.
6. 

   Stir until it's thoroughly mixed.
   Stir until it's thoroughly mixed. It's ready to use now.

Peanut butter blood (edible)

1. Feel free to use in and around the mouth, or on items that may go into the mouth. It should taste much like the peanut butter center of your standard candy peanut butter cup (especially if you add chocolate).
2. Use smooth or creamy peanut butter for best results. Chunky peanut butter will add a coagulated look, but it's harder to work with.
3. Slowly mix in corn syrup until the desired consistency is reached. As the mixture ages, it will thicken a bit, providing more realism.
4. Slowly add single drops of red food coloring until the mixture is dark red; the darker the better - it will look more like real, drying blood.
   • If wished, add a little bit of chocolate sauce or chocolate fudge for a darker color.
   • If you want a thicker mixture, slowly add corn starch (in very small amounts to ensure even mixing). The solution should thicken with time.
5. Note that this mixture may stain clothing, so be sure you don't want to use the clothes for normal wear again.

Barbecue sauce blood for congealed look (edible)

1. This recipe is good for inside of fake wounds and places where you want blood to stay without running.
2. Use a bottle of Sweet Baby Ray's® barbecue sauce and 2 tablespoons of molasses.
3. Slowly stir in the sifted chocolate powder until mixture is desired darkness.

Tomato ketchup or sauce blood (edible)

1. Squeeze 10 teaspoons of ketchup into a bowl.
2. Add 6.7 fl oz or 200ml of water.
3. Add a few drops of dark red edible food coloring.
4. Add a teaspoon of corn syrup.
5. 

   Mix together well, and spoon onto desired area.
   Mix together well, and spoon onto desired area.

Realistic looking edible blood

1. • For this you want your mixture to be roughly be 97% Golden Syrup
   • 2% Plain Flour or Cornflour
   • 1.7% Red food colouring.
   • 0.3% Blue food colouring.
2. Always add the Golden syrup first then add a very small amount of plain flour or corn flour (about a teaspoon) then add a teaspoon of red dye and a drop of blue dye. Give it a good mix then follow these rules:
3. If it is too pink/orange, add red (not blue; only add blue when you have at least put 3 teaspoons in and 1 drop of blue and you're confident it is still not dark enough and only add blue slowly as if it goes too purple you have to start again you cannot fix it with more red)
4. If it is too transparent, add flour.
   • This mix can get quite sticky and may stain clothes but is easily removed from skin with baby wipes or warm water! Tastes quite sweet! Looks real especially in front of a still camera

Soy Sauce Blood to Splatter

1. Take a piece of small plastic tubing and force it onto the end of a syringe. Use tape or glue to make this into an airtight seal.
2. Pour some soy sauce into a cup or bowl and add the red food dye. Add enough to make the blood dark red.
3. Put the end of the tubing in the cup or bowl and pull back the plunge to suck up the blood.
4. Use poster tack to clog the end of the tube. Make sure it's well clogged.
5. Tape this under the clothing and push on the plunger to release a spray of blood.

Movie blood (inedible)

1. Unlike the non-toxic, edible blood, this one won't be sticky. When dribbled from about five feet, this blood will create nice "splatter" patterns, like real blood does. On skin it will flow easily and smear like the real deal. But, be careful how you use it. It can easily get everywhere.
2. Pour about three quarters as much alcohol-free, water-soluble hair gel as the amount of blood you want.
3. Add water-soluble motor or radiator lubricant, any brand. This should be semi-opaque and slightly thicker than water. Start off with a very small amount and mix with the gel until it turns watery.
4. Mix in about half as much red food coloring as there is liquid. Preferably, buy a "super strength" type at a bulk foods store to save money, and skip the cheap, 1 oz (29.5ml) bottles; they look too pink.
5. Add small amounts of chocolate syrup to make the blood browner, and improve the thickness. It shouldn't be too much like water, but still very dribble-like.
6. Add small amounts of hand sanitizer if you're having trouble with a nice, drippy consistency. Be warned, this easily weakens the mixture.
7. 

   Check the mix.
   Check the mix. The final mix should be a little bit thicker than water, deep brownish-red, and about the opacity of milk.

Art supply blood (inedible)

1. 1
   Use Elmers Squeeze Paint Tubes®. This paint is usually very runny. Choose the colors in orange and pink (they don't come with red) and mix.
2. 2
   Squeeze paint onto the desired area.

Kool Aid Blood

1. Get 4-6 packs of Cherry Kool Aid and a teaspoon of egg whites.
2. Put the Kool-Aid into a glass.
3. Add a teaspoon of egg whites.
4. Stir it up.

Beet Root Blood (edible)

1. Buy a large jar of cut beetroot in a jar.
2. Drain the beetroot, put the liquid in a cooking pan. Set aside beetroots to eat later.
3. Bring juice to boil. Mix some (about 2 tablespoons) of cornstarch with cold water until you have a thick mixture. Add this to the boiling juice. # Continue to cook for about 3 minutes.
4. The mixture is ready to use when cooled down enough. It will get thicker when cooling down. If it's not thick enough for your purpose bring back to boil and add more cornstarch.
5. This fake blood will stain and be hard to remove from clothes.
