The Best Fake Blood Recipes for Halloween

There is a science to making the most realistic-looking blood. Put on your scientist safety glasses and get ready for a little experimentation.

Most of the recipes below require only a few ingredients, but don’t get caught up in the exact measurements. It’s all about adding a little of this and a little of that until you get the right color and consistency.

The Goriest, Tastiest, Realistic Fake Blood Recipes | Steve Spangler Science

This fake blood will also be safe to dribble a little out of your mouth, because they are completely edible. But many will stain, so be prepared to look a little funny on November 1st and don’t rub it on clothing you don’t want permanently bloodied. You can wash everything with OxiClean® – it does a great job to remove stains.

Use a white towel, napkin or your skin to test the blood. It will look differently in the blender than it does on your skin. We think blood is red, but it is really reddish-brown. It also isn’t see-through or watery.

Halloween Science Activity Guide | Steve Spangler ScienceOld-Fashioned Glue and Borax Silly Putty Slime

This kind of slime is simple to make and uses common ingredients. The consistency is thick and stretchy. To make the slime see-through, substitute Gel Glue for regular white glue.

The measurements do not need to be exact; the proportions are more important.

  • Empty the glue bottle into the mixing bowl.
  • Fill the empty bottle with warm water and shake.
  • Add water to mixing bowl.
  • Add a few drops of food coloring.
  • Measure ½ cup of warm water into a plastic cup and add a teaspoon of Borax powder.
  • Stir the solution and don’t worry if all of the Borax dissolves.
  • Start stirring the glue and water mixture in the bowl and slowly add a little of the Borax solution.
  • It’s time to abandon the spoon and use your hands to mix. Continue to add the Borax solution until the slime reaches the perfect consistency.

PVA Slime

The Slime-ologists at Steve Spangler Science have created the best slime you’ve ever seen using a PVA formula. PVA, or polyvinyl alcohol, is the substance used in many different products such as garden hoses, contact lens solution and water-soluble packages in detergent “liqui-tabs.”

  • Mix 240 mL (8 oz or 1 cup) of PVA Green, Clear Slime or Atomic Slime from Steve Spangler Science with 60 mL (4 tbsp) cross-linker solution like Borax.
  • Use hands to mix and mush liquid into a slimy consistency.
  • Mix in small plastic spiders, glitter, Water Beads, or Styrofoam beads to create an extra spooky batch for Halloween. Styrofoam beads will make the slime feel like Floam.
  • For Bug Soup Slime add rubber bugs to the slime.

Shaving Cream Marshmallow Slime

This slime isn’t actually fluffy, but reminds us of marshmallows. It has a different texture than regular slime and comes clean on hands. The shaving cream also makes the slime appear silvery and shimmery.

  • Add shaving cream to either of the recipes above.

Glow-in-the-Dark Slime

Who doesn’t love things that glow in the dark? It’s especially spooky for Halloween.

Vampire Slime

Where does slime come from, you ask? Monsters, of course. But thanks to some cool genetic mutations, vampires now have their own slime. Telling the difference between monster slime and vampire slime can be tricky at first glance, unless you know the vampire secret… hold the slime up the light. Ordinary monster slime just looks green (because monster blood is green, dah). Vampire slime, on the other hand, shows its true color when you hold it up to the light because the green turns dark red to reveal what vampires drink… well… you know… that stuff. Leave it to the vampires to find another way to hide their true identity.

 Snot Slime

Use Clear Slime or make Elmer’s Glue Slime with gel glue.

Fairy Slime

Start with Clear Slime or Gel Glue Elmer’s Slime, then add Pearl Swirl, glitter, confetti and a few Water Beads.

Glacier GAK Slime

  • Here’s the easiest way to make a big batch of GAK. The measurements do not have to be exact, but it’s a good idea to start with the proportions below for the first batch. Just vary the quantities of each ingredient to get a new and interesting batch of goo.
  • This recipe is based on using the Elmer’s Glue recipe with a brand new 240 mL (8 oz) bottle of Elmer’s Glue. Empty the entire bottle of glue into a mixing bowl. Fill the empty bottle with warm water and shake (okay, put the lid on first and then shake). Pour the glue-water mixture into the mixing bowl and use the spoon to mix well. Go ahead… add a drop or two of food coloring and mix some more.
  • Measure 1/2 cup of warm water into the plastic cup and add a teaspoon of Borax powder to the water. Stir the solution. Don’t worry if all of the powder dissolves.
  • While stirring the glue in the mixing bowl, slowly add a little of the Borax solution. Immediately you’ll feel the long strands of molecules starting to connect. It’s time to abandon the spoon and use your hands to do the serious mixing. Keep adding the Borax solution to the glue mixture (don’t stop mixing) until you get a perfect batch of Elmer’s slime. You might like your slime more stringy while others like firm slime. Hey, you’re the head GAK mixologist – do it your way!
  • When you’re finished playing with your GAK, seal it up in a zipper-lock bag for safekeeping.

Edible Sewer Slime

What’s better than making slime to squish and squeeze while disgusting your friends? Making slime you can eat. With the right coloring, this edible slime will look like you pulled it from your plumbing. What will your friends say when you drop a piece of sewer slime in your mouth?

Caution: Don’t add anything that isn’t food to this recipe if you plan on putting it in your mouth.

  • Mix 5 mL (1 tsp) of Metamucil with 240 mL (1 cup) of water in a microwavable bowl. The fiber acts as the cross-linker.
  • Add a drop or two of food coloring or Jell-O powder to change the color and flavor.
  • Heat the bowl in the microwave for 4 to 5 minutes or until the slime starts to bubble over the sides of the bowl.
  • Let it cool for a few minutes, and then heat again until it bubbles.
  • You may need to repeat the heating and cooling a few times until the mixture becomes rubbery.
  • Have an adult remove the bowl from the microwave and pour the VERY HOT mixture onto a plate with a spoon.
  • Let cool completely.
  • Drip or let it hang into your mouth
  • Enjoy!

Edible Oobleck Slime

Caution: Don’t add anything that isn’t food to this recipe if you plan on putting it in your mouth.

  • Pour approximately 1/4 of the box of cornstarch into the mixing bowl and slowly add about 1/2 cup of water. Stir. Sometimes it is easier to mix the cornstarch and water with your bare hands–of course, this only adds to the fun.
  • Continue adding cornstarch and water in small amounts until you get a mixture that has the consistency of honey. It may take a little work to get the consistency just right, but you will eventually end up mixing one box of cornstarch with roughly 1 to 2 cups of water. The mixture gets thicker or more viscous as you add more cornstarch.
  • Once you get it to a good, slimy consistency, add a few drops of food coloring or dry Jell-O and mix. Keep in mind the coloring will stain hands and clothes.
  • Grab a spoonful and drop it in your mouth.
