Learn how to make slime without glue using guar gum! This easy no glue slime recipe creates a fun jiggly texture while introducing kids to natural polymers and material science.
As the guar gum absorbs water, it forms a unique slime-like material that stretches, flows, and behaves differently from traditional glue-based slime. It’s a simple way to explore polymer science through hands-on play.
The Science Behind It
Field: Chemistry—Polymers & Materials Science
Grades: K–5
Concepts Explored: Polymers, natural polymers, viscosity, material properties, sensory science, observations, and comparisons.
This slime recipe is a fun way to explore how natural polymers behave when mixed with water. If you enjoy slime science, be sure to learn more about polymers and how different slime recipes create different material properties.
Key Ingredient For Making Glue-Free Slime
The secret ingredient in this no glue slime recipe is guar gum.
Guar gum is a natural thickener made from guar beans. It is commonly used in foods, cosmetics, and household products because it absorbs water and creates thicker textures.
When mixed with water, guar gum forms a unique jiggly slime that feels very different from traditional glue-based slime.
Note: This is not an edible slime recipe. Although guar gum is commonly used in foods, this recipe also contains slime activator ingredients and is intended for play only.
Easy Guar Gum Slime Recipe Without Glue
This unique slime recipe uses only a few simple ingredients and comes together quickly. We found guar gum in the specialty baking section of our local grocery store, but it is also available online.
YOU WILL NEED:
- 1/2 teaspoon guar gum
- 1 cup warm water
- 1/2 teaspoon baking soda
- 1 teaspoon saline solution
- Food coloring (optional)
How To Make No Glue Slime
Step 1
Add 1 cup of warm water to a bowl. Sprinkle the guar gum over the water and stir well until no lumps remain.
Step 2
Add food coloring if desired.
Step 3
Add the baking soda and saline solution.
Step 4
Continue stirring and watch the slime begin to form.
Step 5
Once fully mixed, pick up the slime and give it a jiggle!
What Happened?
The guar gum absorbs water and forms a thick, jiggly material with unique flow properties. Unlike traditional slime, which relies on glue as the primary polymer, this recipe uses a natural plant-based polymer.
The result is a stretchy, wiggly slime that behaves differently from both a liquid and a solid.
What Is Guar Gum?
Guar gum is a natural thickener made from guar beans.
You may find it in:
- Ice cream
- Yogurt
- Sauces
- Salad dressings
- Gluten-free baked goods
Because guar gum contains long polymer chains, it can absorb water and create thicker textures.
💡 Scientists use materials like guar gum to study how polymers behave in liquids and gels.
The Science Of Guar Gum Slime
This slime recipe is a great example of polymer science.
A polymer is a material made of many repeating units connected together into long chains.
Guar gum is a natural polymer. When mixed with water, the long polymer chains absorb water and expand.
As the chains spread out and interact with one another, the mixture becomes thicker and develops its signature jiggly texture.
The baking soda and saline solution help create the slime-like consistency, producing a material that can stretch, flow, and hold its shape.
Is Guar Gum Slime A Polymer?
Yes!
Guar gum slime demonstrates how natural polymers can create slime-like materials without using glue.
Natural polymers are found throughout nature and include:
- Guar gum
- Gelatin
- DNA
- Proteins
- Starch
This makes guar gum slime one of the easiest ways to explore natural polymers using simple household ingredients.

Polymer Investigation For Kids
Scientists study materials by testing how they stretch, flow, bend, and return to shape.
Try comparing:
- Guar gum slime
- Traditional slime
- Oobleck
Observe:
- Which material stretches the most?
- Which material flows the slowest?
- Which material feels the most solid?
- Which material jiggles the most?
Small differences in ingredients can create very different material properties.
Guar GumSlime FAQ
What is guar gum slime? Guar gum slime is a no glue slime made with guar gum, water, baking soda, and saline solution.
What is guar gum? Guar gum is a natural thickener made from guar beans and commonly used in foods and household products.
Is guar gum slime a polymer? Yes. Guar gum contains long polymer chains that absorb water and create its unique texture.
Does guar gum slime stretch? Yes, but it is known more for its jiggly, wiggly texture than long stretchy strands.
Is this an edible slime recipe? No. Although guar gum is a food ingredient, the finished slime is intended for play only.
How is guar gum slime different from regular slime? Traditional slime uses glue as the primary polymer. Guar gum slime uses a natural plant-based polymer instead.

Definitely going to use this recipe. My granddaughter won’t stop making the glue slime.
I made this slime (saline solution, guar gum recipe) about a week ago and it has been played with daily. I opened the container yesterday and it was a liquid. Is this normal or did I do something wrong? I want to make for party gifts but I don’t want it to turn to a liquid.
This is normal. It doesn’t hold together like traditional slime for as long. I am surprised it lasted a week!
Yes it’s pretty normal. It doesn’t hold together like traditional glue slimes.
Can you use Xanthum Gum instead of Guar Gum and still have the same results?
