We have had fun with Jello slime, now play with an easy edible green slime! The slime fun continues with cool gelatin slime that’s also messy sensory play! Just a few common kitchen ingredients and you can make gooey edible slime. We love homemade slime especially one that’s edible. This slime recipe does not contain Metamucil but it does have a good amount of sugar!

Edible Slime For Kids

I don’t tend to like edible play materials and don’t make them often. Our Ice Cream in a Bag experiment, however, was a yummy science experiment. However, if you need taste-safe recipes for kids who are still testing with their mouths edible slime is the way to go!

There’s nothing healthy about our edible slime and we didn’t find it all that tasty, but it is certainly taste safe with simple ingredients! We added lime juice for a little extra taste. I found the initial recipe at Sci-Borg Projects. We made two versions. This edible gelatin slime below is a goo like substance and our next gelatin slime more like a fake snot! Cool science!

This gelatin slime is certainly a science activity for the senses. Yes, you can taste it. I did and it was ok but not something to chow down on which was fine by me. My son and husband were unwilling to try it but happily watched me eat a piece.

Remember this is simple unflavored gelatin {like jello} with corn syrup {sugar} mixed together. Add any flavor you want or leave as is for cool gelatin slime.

Gelatin Slime Recipe

We tested our slime recipe with corn syrup and gelatin a few times. No matter what you end up with, this gelatin slime is slimy and fun for kids and adults too!


  • 3 packs Knox Unflavored Gelatin
  • 1/4 cup Corn Syrup
  • Water
  • Food coloring and or flavoring


STEP 1: Boil the water and add green food coloring.

STEP 2: Mix the gelatin into the water slowly, but it may still form a few clumps.

STEP 3: Then add in a 1/4 cup of corn syrup and mix together.

The Science of Gelatin

This is messy science! Check out our basic slime science about polymers. Although this slime is made with gelatin, the mixture of water and gelatin still makes a polymer. The proteins in the gelatin combine with the corn syrup to form gooey strands that resemble slime and even fake snot.

Playing around with the amount of corn syrup you use will change the texture. The more corn syrup added the longer the strands will be and the more it will resemble fake snot. The less corn syrup you use the more glob like and chunky it becomes. Our edible green slime recipe above is halfway between the two textures.

TIP: Play around with different amounts of corn syrup to check out different textures!

  1. Thanks for posting these great ideas. I am most happy to find an ‘edible’ recipe for slime however I have not been successful with this particular recipe yet even with considerable experimentation.
    I’ve used
    1/2 boiling water
    x3 sachets of non flavoured gelatin (10 g a sachet compared with knox gelatin’s 7g per sachet)
    experimented with 1/8 to 1/2 cup of light corn syrup
    2 drops of green food coloring.

    I currently have it in the fridge to see if that makes a difference but I was expecting the polymer to happen immediately much like borax/glue slime. Are you able to help me out?

    Thanks for your help!!

  2. I did a bit of experimenting my self and my measurements are exactly what worked for us. I am not sure if temperature, location, or water could have an effect on it. The edible slime is certainly more gooey and messy than our traditional slime.

  3. We could not get the right consistency with the flavored gelatin so you may need to experiment a bit!
