How To Make Gelatin Slime

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!

Ingredients:

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

Instructions:

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!
