Step-by-Step process of making Slime with Toothpaste

Making Slime with Toothpaste is a very easy and engaging process. However, Toothpaste alone cannot do the job, so gather some additional kitchen ingredients like food color and Cornstarch. Once you have them all, here’s how you can process:

  1. Firstly, take a plastic or glass mixing bowl and squeeze out your regular White Toothpaste in a generous amount. Do not skimp, as you will require a lot of Toothpaste for this DIY Slime. Also, avoid using colored, striped, or textured Toothpaste.
  2. Now, take a tablespoon of Cornstarch, add it to the Toothpaste, and mix it using a spoon. Keep mixing until both ingredients are combined well. 
  3. Next, take the food coloring (liquid or powder) of your choice and add a little of it to the Toothpaste- Cornstarch paste. You can mix two or more colors as well to create a different shade. Keep mixing until the color is dissolved well into the entire paste. 

NOTE: If the Toothpaste- Cornstarch mixture is too thick/ hard, you can add a little water, though be mindful. Or, if the mixture is too runny, you will need to add some Cornstarch again.

  1. Once you observe that the Slime has reached a medium consistency, start kneading it with your hands. It will take a few minutes of effort before you end up with a smooth and stretchy slime-like dough. And with that, your DIY Slime is already. If you want your DIY Slime to stay fresh for a long make sure you store it in an airtight container. Storing it in an air-exposed box will dry the Slime within no time, wasting all your efforts. 

If you are into the creative side, you can add different colors, glitters, beads, or textures to make your DIY Slime more exciting. 

How do Toothpaste and Cornstarch form Slime?

Toothpaste and Cornstarch can form Slime, but how that happens is a matter of confusion.

Well, when you combine Toothpaste and Cornstarch, their physical and chemical properties react and form a slimy paste.

Ingredients like Sodium Lauryl Sulphate in toothpaste act as a surfactant. It reduces the surface tension of liquids. And when you mix it with Cornstarch, a hydrophilic substance, it breaks down the cornstarch particles. The end result is a smooth and slimy dough or your very own DIY Slime.  

When you add Cornstarch to Toothpaste, it gives it a unique consistency. And as you continue kneading it with your hand, both ingredients combine to form a stretchy dough or a cohesive substance. This fun DIY is definitely a very rewarding experience and undoubtedly a satisfying one as well. 

How to make Slime with Toothpaste and Shampoo?

Done with making Slime with Toothpaste and Cornstarch? Well, then try making Slime with Toothpaste and Shampoo. Here’s how you can do the same:

  1. Firstly, take a bowl and squeeze out a lot of regular white Toothpaste into it. Gather as much toothpaste as depending on the quantity of Slime you want to make. 
  2. Now add a few pumps of shampoo into the same bowl, and using a spoon continue mixing both ingredients. Keep mixing until Toothpaste and shampoo have formed a consistent paste. 
  3. Next, use your hand and knead the toothpaste and shampoo mixture until it turns into something like Slime. You might need to add more Toothpaste or shampoo if the mixture is too dry or runny. Add a little by little just to balance out the consistency. 
  4. Later once you achieve the desired consistency, your DIY Toothpaste and shampoo slime are ready to play with. 

TIP: Instead of Shampoo, you can also use Hand Sanitizer to make your DIY Slime.

When we combine Toothpaste and shampoo, they create a polymer giving the mixture a unique slimy texture. Ingredients like sodium lauryl sulfate, sodium fluoride, and glycerin in both Toothpaste and shampoo combine together and form long chains of molecules.

As you continue mixing and kneading them both, the pressure of your hand breaks up any clumps and makes them slimy. The more you will knead, the more this mixture will become stretchy and pliable. 

However, the Slime you make by combining Toothpaste and Shampoo may not be most stable and very long-lasting as with other ingredients.
