Fake snot is a must try for cool science, gross science, or even your next kids’ party! Easy to make with a few kitchen ingredients, fake snot slime is even edible or at the very least taste safe. This is one of our favorite slime alternatives. Do you know someone who will enjoy this totally gross, totally cool, totally fake snot activity?
Fake Snot Recipe
💡 We do not often make Taste safe or edible slime, but sometimes you just need an alternative to the classic slime recipes that use liquid starch, saline solution, or borax powder.
Supplies:
- Unflavored Gelatin, 3 packs
- Corn Syrup
- Water
- Food Coloring
Method:
TIP: I like to use two bowls to make this fake snot.
STEP 1. Mix 1/2 cup of boiling water and three packets of Knox brand unflavored gelatin in one bowl. Mix the gelatin and water with a fork. Add the gelatin in slowly but it will still tend to clump just the same. Let it stand for 5 minutes.
STEP 2. In another bowl, measure out 1/2 cup of corn syrup. Slowly add the gelatin mixture to the corn syrup until it reaches the desired consistency—snot-like! The fork helps to pull up cool strands of fake snot!

What’s The Science?
This is definitely messy sensory science play! Although slime is made with gelatin, the water and gelatin mixture still make a polymer. The proteins in the gelatin combine with the corn syrup to form gooey strands that resemble your snot.
The equal parts gelatin mixture to corn syrup made the perfect fake snot you could pick up and watch flow like mucous. We used less corn syrup for our edible slime and made a thicker texture. Play around with different amounts of corn syrup to check out different textures.

Have you always wanted to play with fake gooey snot? You can even taste it too! It’s simply gelatin and sugar, but is not very tasty.

Ewww! SO awesomely gross 🙂
Can you use flavored jello?
No you really do need the unflavored kind for it to work correctly.
How much “snot” does this recipe make?
It makes a about a handful!
We tried this today as a “Slime Challenge” where each person was blindfolded and had to guess what edible ingredient they were adding. Strawberry jam slime is delicious!
What’s the best way to remove snot slime from clothing? If it has been rubbed into clothing!?
Well it is gelatin, so maybe soaking in warm soapy water would work!
Thank You
Is the color natural? Or did you add coloring to make it look greenish?
