How to Make Fake Vomit

Vomit is a great way to stay home or get revenge. Instead of making yourself sick on purpose, why not make some fake vomit instead? There are lots of ways to make it using stuff from your kitchen. Vomit is just mixed up food from your last meal, so you can use just about anything. There are some recipes you can use to make it extra-gross and realistic, however. You can even use glue to make it reusable!

Method 1
Method 1 of 4:

Crackers and Water

    1
    Chew up some crackers. You can also break them up with your hands as well.[1] If you can't find any crackers, you can use biscuits or light-colored cookies (ie: vanilla wafers, sugar cookies, graham crackers, etc.). Don't use chocolate chip cookies or Oreos—those are way too dark!

    2
    Spit the crackers into a plastic bag. You can use a bowl, sink, plastic bag, or even a toilet.[2] If you want to make more vomit, chew up and spit out more crackers.

    Add some water, if needed. If you spat the crackers into a toilet, you don't need anymore water. If you spat them into a bowl, bag, or sink, then add in a little water. This makes the vomit look more real.[3]
    • You can also try some white vinegar, apple cider vinegar, apple juice, or even a little milk.

    Add something mushy and smelly. Wet cat food or wet dog food work great for this. You can also use a little bit of canned tuna or baby food. It will help make the vomit look (and smell!) more real.[4] You could also chew up some cereal, spit it out, then mix it with vinegar.

    Leave the vomit for someone to find. If you used the toilet, don't flush it! If you left it in a bowl or trash bag, you could take it to a parent, guardian, or teacher, and say that you threw up.
Method 2
Method 2 of 4:

Crackers, Oatmeal, and Carrots

  1. Image titled Make Fake Vomit Step 6
    1
    Crush 10 crackers into bowl. Make sure that the bowl is safe to go into the microwave. If you can't find any crackers, some cookies or cereal would also work.
  2. Image titled Make Fake Vomit Step 7
    2
    Add ½ cup (40 grams) of dry oatmeal. The large, chunky flakes will look the best, but you can use the kind that are cut up too.
  3. Image titled Make Fake Vomit Step 8
    3
    Pour in 1 cup (240 milliliters) of water. Stir it with a spoon. Mash those cracker bits up so they get soggy.
  4. Image titled Make Fake Vomit Step 9
    4
    Microwave it for 30 seconds. This will be just enough to make the vomit a little chunky, but still watery. Use oven mitts or a pot holder to take the bowl out of the microwave.
  5. Image titled Make Fake Vomit Step 10
    5
    Toss in some corn or chopped up carrots. You could also chew up a mini carrot, then spit it back into the bowl. This will make the vomit look even more real.
  6. Image titled Make Fake Vomit Step 11
    6
    Add in a squirt of honey. This will help give it some color and ickyness. If you don't have honey, you could try maple syrup, agave nectar, or pancake syrup.
  7. Image titled Make Fake Vomit Step 12
    7
    Stir it up with a spoon. Make sure that you scrape the bottom and sides of the bowl.
  8. Image titled Make Fake Vomit Step 13
    8
    Let the vomit cool before you use it. Pour it down the front of your shirt, or dump it into the toilet. Get some on the floor. You can also take some into your mouth, then lean over and spit it out. Make some puking sounds!

Method 3 of 4:

Applesauce, Oatmeal, and Cereal

  1. Image titled Make Fake Vomit Step 14
    1
    Heat up ¼ cup (45 grams) of applesauce. Pour the applesauce into a small pan, and place it on the stove. Turn the heat up to low or medium. Wait for the applesauce to get hot enough to make steam.[6]
    • Any type of applesauce will work. If you can't find any, try baby food.
  2. Image titled Make Fake Vomit Step 15
    2
    Stir in a packet of gelatin. Don't use flavored gelatin, like Jello, or the vomit may change color.[7]
    • If you only have Jello at home, try yellow or orange. It will give you a more natural color.
  3. Image titled Make Fake Vomit Step 16
    3
    Add in 1 to 2 pinches of cocoa powder. Give the vomit another stir. Sprinkle it over the contents in the frying pan and stir. This will help give the vomit some color.[8] If you can't find any cocoa powder, you can use hot chocolate mix or even a pinch of dirt.
  4. Image titled Make Fake Vomit Step 17
    4
    Take the pan off the stove. Set it down onto a trivet or folded towel so that you don't ruin the counter.
  5. Image titled Make Fake Vomit Step 18
    5
    Add in some oatmeal and cereal for texture. You will need a small handful of each. Give the vomit another stir to mix everything in.[9] If the cereal has large flakes, you can crumble them with your hands first.
    • If you don't have Raisin Bran or Cornflakes, you can use another type of brownish, flaky cereal. Granola is a great one!
  6. Image titled Make Fake Vomit Step 19
    6
    Spread the fake vomit onto a plate. Use a spatula to move the vomit from the pan to a plate. Spread it around into a vomit shape with a spoon. If you want to, you can add more oatmeal or crushed cereal on top.[10] Don't get too carried away!
  7. Image titled Make Fake Vomit Step 20
    7
    Let the vomit cool for a few hours. After that, you can take the vomit off the plate with a spatula and put it somewhere to gross someone out.[11]

Method 4 of 4:

Using Glue

  1. Image titled Make Fake Vomit Step 21
    1
    Squeeze out some glue into a mixing cup. You can use a decoupage glue, like Mod Podge, or white school glue. Plan on squeezing out about 1/4 to 1/2 cup (60 to 120 milliliters).[12]
    • Use a cup that you can throw away, like a paper one.
  2. Image titled Make Fake Vomit Step 22
    2
    Add a hint of brown. You just need a tiny drop of brown food coloring, water color, or paint. The vomit will look light tan now, but it will get darker after it dries.[13]
  3. Image titled Make Fake Vomit Step 23
    3
    Stir it up until the color is even. You can use just about anything to stir: a plastic spoon, a popsicle stick, a toothpick, etc.[14]
  4. Image titled Make Fake Vomit Step 24
    4
    Pour half of it out onto a sheet of parchment paper. Place the parchment paper onto a baking sheet first. Next, pour the glue onto the parchment paper into a vomit shape. Save the rest of the glue for later.[15]
    • You can also use a sheet of wax paper or even plastic wrap.
  5. Image titled Make Fake Vomit Step 25
    5
    Add something chunky. A handful of dry cat or dog food will look gross. If this is human vomit, you could try a handful of dry oatmeal or granola. Put most of the chunks in the middle of the glue puddle, and a few bits on the edges.[16]
  6. Image titled Make Fake Vomit Step 26
    6
    Cover the chunky bits with the rest of the glue. Simply pour the rest of your colored glue over the vomit puddle. Make sure that you cover all the chunky bits you added in. This will help seal them in.[17]
  7. Image titled Make Fake Vomit Step 27
    7
    Wait for the glue to dry. The glue will turn clearish once it dries. This may take a few days. If you get impatient, let it dry for about 48 hours, then bake it for about 10 minutes in the oven at 275°F (135°C).[18]
    • If you want to bake it, open up a window. It will stink!
    • Don't put wax paper or plastic wrap into the oven. If you used those, you'll have to let it air dry.
  8. Image titled Make Fake Vomit Step 28
    8
    Peel the vomit off. The glue will dry semi-flexible, but be careful not to bend it too much. Leave the vomit some place for your victim to find, like the floor or their pillow. Because this vomit is made from glue, it should last a very long time.[19]

    Milk and chewed up chunks of bread work, too. Vomit is pretty much just mixed up food. You can also put random food items into a blender, along with some water, milk, juice, or vinegar, and use that instead.
