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

You can also break them up with your hands as well.^{[1]

Research source} 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!
You can use a bowl, sink, plastic bag, or even a toilet.^{[2]
X
Research source} 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.
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]

Research source} You could also chew up some cereal, spit it out, then mix it with vinegar.

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 of 4:

Crackers, Oatmeal, and Carrots

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.
The large, chunky flakes will look the best, but you can use the kind that are cut up too.
Stir it with a spoon. Mash those cracker bits up so they get soggy.
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.
You could also chew up a mini carrot, then spit it back into the bowl. This will make the vomit look even more real.
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.
Make sure that you scrape the bottom and sides of the bowl.
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
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]
X
Research source}
- Any type of applesauce will work. If you can't find any, try baby food.
2
Stir in a packet of gelatin. Don't use flavored gelatin, like Jello, or the vomit may change color.^{[7]
X
Research source}
- If you only have Jello at home, try yellow or orange. It will give you a more natural color.
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]
X
Research source} If you can't find any cocoa powder, you can use hot chocolate mix or even a pinch of dirt.
Set it down onto a trivet or folded towel so that you don't ruin the counter.
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]
X
Research source} 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!
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]
X
Research source} Don't get too carried away!
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

Download Article

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]
X
Research source}
- Use a cup that you can throw away, like a paper one.
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]
X
Research source}
You can use just about anything to stir: a plastic spoon, a popsicle stick, a toothpick, etc.^{[14]

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]
X
Research source}
- You can also use a sheet of wax paper or even plastic wrap.
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]
X
Research source}
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]

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]
X
Research source}
- 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.
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]

Are there any easy ways?

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.
