Creating fun and engaging activities for kids doesn’t have to be complicated or expensive. With just a few household items, you can make a fantastic slime that will keep them entertained for hours. In this guide, we’ll show you how to make slime with toothpaste and salt, a simple and budget-friendly option that is surprisingly satisfying to play with. Get ready to witness the transformation of ordinary ingredients into a delightfully gooey and stretchy substance!
To begin, gather the necessary materials: white toothpaste (non-gel), salt, a mixing bowl, a spoon, and water. The ratio of toothpaste to salt will determine the consistency of your slime, so adjust it based on your preference. Start with a 2:1 ratio of toothpaste to salt, meaning two parts toothpaste to one part salt. In a mixing bowl, combine these ingredients and mix thoroughly until a paste forms. If the mixture seems too thick, gradually add water a teaspoon at a time until it reaches a smooth and spreadable consistency.
Now comes the exciting part: activating the slime! Slowly add salt to the toothpaste mixture while continuously stirring. As you add salt, the slime will begin to thicken and clump together. Continue stirring until the slime pulls away from the sides of the bowl and forms a solid mass. If the slime is still too sticky, add more salt; if it’s too dry, add a bit of water. Once you achieve the desired consistency, knead the slime with your hands to further develop its elasticity and smoothness. And voilà! Your homemade toothpaste and salt slime is ready to be played with, squished, and stretched to your heart’s content.
The Perfect Ratio for Toothpaste and Salt
To achieve the ideal consistency for your slime, it’s crucial to establish the perfect balance between toothpaste and salt. This ratio varies depending on the specific toothpaste brand and salt type you use, as well as your desired slime texture. However, a general starting point is to use equal parts of toothpaste and salt by volume. For example, if you use 1 tablespoon of toothpaste, add 1 tablespoon of salt.
To help you visualize this ratio, here’s a detailed table:
| Toothpaste | Salt |
|---|---|
| 1 part | 1 part |
Once you have the basic ratio established, you can adjust it slightly until you achieve the desired slime texture. If you want a firmer slime, add more salt. For a more flowy slime, add more toothpaste. It’s recommended to experiment with different ratios until you find the one that works best for your preferences.
Essential Tips for Successful Slime Making
1. Use the Right Type of Toothpaste
(
It’s important to use a toothpaste that contains sodium fluoride, as this ingredient helps to create the cross-linking reaction that forms the slime. Avoid using toothpastes that are gel-based or contain baking soda, as these will not work as well.
)
2. Measure the Ingredients Carefully
(
The ratio of toothpaste to salt is crucial for the success of your slime. If you use too much salt, the slime will be too stiff and crumbly. If you use too little salt, the slime will be too sticky and runny.
)
3. Mix the Ingredients Thoroughly
(
Once you have added all of the ingredients to your bowl, it’s important to mix them thoroughly until they are completely combined. This will help to ensure that the slime is smooth and has a uniform consistency.
Here are some detailed tips on how to mix the ingredients properly:
- Use a spoon or spatula to stir the ingredients together in a circular motion.
- Be sure to scrape the sides of the bowl as you stir, so that all of the ingredients are incorporated.
- Continue stirring until the slime is smooth and has a uniform consistency.

Step-by-Step Instructions
- In a large bowl, combine the toothpaste, salt, and water.
- Stir until the ingredients are well combined and form a smooth paste.
- If the mixture is too thick, add more water 1 teaspoon at a time until it reaches the desired consistency.
- If the mixture is too thin, add more salt 1 teaspoon at a time until it thickens.
- Glitter and Add-Ins: Once the base slime is complete, it’s time to add your desired glitter and add-ins.
| Add-In | Instructions |
|---|---|
| Glitter | Sprinkle a pinch of glitter into the slime and knead until evenly distributed. |

| Beads | Drop a handful of beads into the slime and knead until they are evenly dispersed. |
| Sequins | Sprinkle a generous amount of sequins into the slime and knead until they are evenly embedded. |
| Essential oils | Add a few drops of essential oil and knead until the scent is evenly distributed. |
Troubleshooting Common Slime Problems
Slime Is Too Sticky
If your slime is too sticky, it means there is too much liquid. Add a small amount of borax solution (1 teaspoon of borax powder dissolved in 1 cup of warm water) at a time and mix until the desired consistency is reached.
Slime Is Too Runny
If your slime is too runny, it means there is too much water. Add a small amount of cornstarch at a time and mix until the desired consistency is reached.
Slime Is Too Hard
If your slime is too hard, it means there is too much borax. Add a small amount of water at a time and mix until the desired consistency is reached.
Slime Is Not Forming
If your slime is not forming, it means there is not enough borax. Add a small amount of borax solution (1 teaspoon of borax powder dissolved in 1 cup of warm water) at a time and mix until the slime starts to form.
Slime Is Discolored
If your slime is discolored, it means that the food coloring you used was not colorfast. Try using a different brand of food coloring or adding a small amount of white vinegar to the slime to help remove the discoloration.
Slime Is Lumpy
If your slime is lumpy, it means that the ingredients were not mixed well. Mix the ingredients more thoroughly until the slime is smooth.
Storage Techniques for Long-Lasting Slime
To ensure the longevity of your homemade slime, proper storage is essential. Here are some effective techniques to extend its lifespan:
Airtight Container
The most crucial step is to store the slime in an airtight container. This prevents dehydration and air exposure, which can cause the slime to dry out and become brittle.
Cool and Dry Environment
Exposing slime to heat or moisture can accelerate its deterioration. Choose a cool and dry location for storage, such as a refrigerator or a pantry away from direct sunlight.
Plastic Wrap or Ziploc Bag
If you don’t have an airtight container, you can wrap the slime tightly in plastic wrap or place it in a resealable Ziploc bag. This provides an additional layer of protection against air exposure.
Avoid Contact with Other Chemicals
Certain chemicals, such as cleaning agents or solvents, can react with slime and damage its texture or color. Keep the slime away from any potential contaminants.
Regular Monitoring
Check the slime periodically for any signs of degradation, such as dryness or discoloration. If necessary, add a few drops of water or lotion to restore its consistency and freshness.
Additional Tips
Below are some additional tips for long-lasting slime storage:
| Tip |
|---|
| Use non-toxic ingredients to ensure the safety of the slime, especially for children. |

The Science Behind Slime Making
What is Slime?
Slime is a non-Newtonian fluid, which means it exhibits properties of both liquids and solids. When a force is applied, slime behaves like a solid, but when left undisturbed, it flows like a liquid. This unique behavior is due to the cross-linking of polymer chains within the slime.
