How to Make Slime with Cornstarch and Shampoo: The Ultimate Guide
Making slime with cornstarch and shampoo is a simple and fun activity that requires only two ingredients. By mixing equal parts of cornstarch and shampoo, you can create a moldable, play-dough-like substance that provides hours of entertainment and sensory stimulation.
Introduction: The Magic of Two-Ingredient Slime
Slime has become a global phenomenon, captivating children and adults alike. Its squishy, stretchy texture provides a unique sensory experience, making it a popular choice for play and stress relief. While many slime recipes involve complex ingredients and borax-based activators, this guide focuses on a remarkably simple and safe method: using just cornstarch and shampoo. This method is particularly attractive for its accessibility, requiring only two common household items and avoiding the potential skin irritation associated with some other slime recipes.
Why Cornstarch and Shampoo? The Science Behind the Slime
The success of this slime recipe lies in the interaction between cornstarch and shampoo. Cornstarch, also known as corn flour, is a fine powder derived from corn. It acts as a thickening agent, giving the slime its body and structure. Shampoo, on the other hand, provides the necessary moisture and acts as a binding agent, holding the cornstarch particles together. The specific surfactants and polymers in shampoo influence the final texture and consistency of the slime. This is why different shampoos may yield slightly different results.
Benefits of Making Cornstarch and Shampoo Slime
This easy slime recipe offers several advantages:
- Simplicity: Requires only two ingredients, making it incredibly easy to make.
- Safety: Avoids the use of borax, a common slime activator that can cause skin irritation for some individuals.
- Accessibility: Both cornstarch and shampoo are readily available and relatively inexpensive.
- Sensory Stimulation: Provides a fun and tactile sensory experience.
- Customization: Easily customizable with food coloring, glitter, or essential oils.
The Step-by-Step Process: Creating Your Perfect Slime
Follow these simple steps to create your own cornstarch and shampoo slime:
- Gather Your Supplies: You will need cornstarch, shampoo, a mixing bowl, and a spoon or spatula.
- Combine Ingredients: In the mixing bowl, add equal parts of cornstarch and shampoo. Start with a small amount (e.g., 1/4 cup of each) and adjust as needed.
- Mix Thoroughly: Stir the mixture with the spoon or spatula until it starts to come together.
- Knead with Hands: Once the mixture becomes difficult to stir, start kneading it with your hands. Continue kneading until it forms a smooth, pliable ball.
- Adjust Consistency: If the slime is too sticky, add a little more cornstarch. If it is too dry, add a little more shampoo.
- Play and Enjoy: Once you achieve the desired consistency, your slime is ready to play with!
Troubleshooting: Common Problems and Solutions
Even with a simple recipe, some issues can arise. Here’s how to handle them:
| Problem | Solution |
|---|---|
| Too Sticky | Add more cornstarch, a little at a time, and knead until the stickiness reduces. |
| Too Dry/Crumbly | Add a little more shampoo, a drop or two at a time, and knead thoroughly. |
| Not Forming | Ensure you’re using equal parts cornstarch and shampoo. Mix vigorously. |
| Smelly | Try using a different shampoo with a more pleasant scent. |
Customization: Making Your Slime Unique
- Food Coloring: Add a few drops of food coloring to create vibrant and colorful slime.
- Glitter: Mix in glitter for a sparkly and dazzling effect.
- Essential Oils: Add a drop or two of essential oils (like lavender or peppermint) for a calming or invigorating scent.
- Small Toys: Mix in small toys or beads for added texture and visual interest.
- Lotion: A tiny bit of lotion can increase the “stretchiness” of the slime.
Safety Precautions
While cornstarch and shampoo slime is generally safe, it’s important to take a few precautions:
- Supervision: Children should be supervised while making and playing with slime.
- No Ingestion: The slime is not edible and should not be ingested.
- Allergies: Be aware of any potential allergies to shampoo ingredients.
- Storage: Store the slime in an airtight container to prevent it from drying out.

Frequently Asked Questions (FAQs)
What kind of shampoo works best?
The best type of shampoo to use is a thick, opaque shampoo. Clear shampoos often don’t work as well. Experimenting with different brands can help you find one that gives you the best results.
Can I use baby shampoo?
Yes, you can use baby shampoo. Baby shampoo is often milder and gentler, which makes it a good option, especially for children with sensitive skin. However, you may need to adjust the amount of cornstarch to achieve the desired consistency.
How long does this slime last?
The lifespan of this slime depends on how it’s stored and how often it’s played with. When stored in an airtight container at room temperature, it can last for several days to a week.
My slime is too stiff, what do I do?
If your slime is too stiff, add a small amount of shampoo, a drop or two at a time, and knead it thoroughly until it becomes more pliable.
Can I add shaving cream to this slime?
While possible, adding shaving cream to this specific recipe may not yield desirable results. Shaving cream often introduces more moisture and can make the slime too sticky.
Is this slime edible?
No, this slime is not edible. While the ingredients are relatively harmless in small quantities, they are not meant for consumption and may cause stomach upset.
How do I store this slime?
Store your slime in an airtight container at room temperature to prevent it from drying out or becoming moldy.
Can I use other types of starch instead of cornstarch?
While cornstarch is the most commonly used and recommended starch, you can experiment with other types of starch, such as tapioca starch or potato starch. However, the results may vary.
How can I make the slime more stretchy?
Adding a very small amount of lotion can help to make the slime more stretchy. Be careful not to add too much, as it can make the slime too sticky.
Can I add water to the slime to make it less stiff?
It is not recommended to add water directly to the slime. This will make the texture go very wrong and you will not be able to use it. Instead, try adding more shampoo.
Will this slime stain my clothes or furniture?
While the ingredients are generally non-staining, it’s always best to test the slime on a small, inconspicuous area before allowing children to play with it on clothes or furniture.
What do I do if my child gets slime in their hair?
If slime gets in your child’s hair, try rinsing it with warm water and applying conditioner. The conditioner will help to loosen the slime and make it easier to remove.
