How to Make Slime with Shampoo and Toothpaste

• Mix 2 tbsp (30 mL) of thick shampoo and 1 tsp (5 mL) of toothpaste together to form the base of your slime.
• Add more shampoo to your slime mixture if it’s too hard, or add more toothpaste if it’s too runny.
• Put your slime in the freezer for at least 10 minutes and up to 1 hour until it’s your desired consistency.

Basic Shampoo and Toothpaste Slime

Pour a dollop of thick shampoo into a little dish. Any shampoo will work, but one with a thicker consistency works best. Put two squeezes, or about 2 tbsp (30 mL), of the shampoo into a dish you can stir the slime together in later. Try adding 1 or 2 drops of food coloring to the shampoo if you want colored slime.

Add a small amount of toothpaste to the shampoo. Opaque toothpaste (white or mint colored) works best, but you can also try the striped kind. Use a quarter of the amount of toothpaste you did shampoo. About 1 tsp (5 mL) or so is enough. Slime makers have the most success with brand toothpaste, but any brands should do the trick.

Stir the shampoo and toothpaste together. Use a craft stick, toothpick, or spoon. As you stir, the shampoo and toothpaste will come together to form a gooey substance. Keep stirring until it’s well combined, which should take about a minute.

Add more shampoo or toothpaste, if needed, and continue stirring. If the slime is too hard, add some more shampoo. If the slime is too runny, add more toothpaste. Stir the slime well for another minute or so, or until it’s the same color and texture. There’s no right or wrong way to make this slime. Make it to match your preferences!

Freeze the slime for 10 to 60 minutes. Chilling the slime is essentially the “activator” of this recipe as it binds the ingredients together to create a moldable consistency. Check the slime in 10-minute increments until it reaches your desired consistency. Take a close look at the slime in the freezer and make sure no ice particles are forming on top. If ice forms, move it to a different spot in the freezer or pop it in the fridge for around 6 hours.

Knead the slime until it softens up. Take the slime out of the freezer. Roll, squish, and squeeze the slime between your fingers until it becomes soft and squishy again. The slime won’t turn runny like before but will be easily moldable.

Play with the slime until it dries out. This slime is very thick, almost like putty. You can squish, squeeze, and stretch it. When you're done playing with it, put it away into a small plastic container with a lid. The slime will eventually dry out, so throw it away and make a fresh batch when it becomes too hard to mold.

Salt Slime

Squeeze 1 to 2 tbsp (15 to 30 mL) of shampoo into a little dish. About 1 to 2 quick squeezes of any thick shampoo will do. If you want your slime to be colored, consider using a colored shampoo or adding a few drops of food coloring.

Add about ½ tbsp (7 mL) of toothpaste to the shampoo. Use roughly a third of the amount of toothpaste as you did shampoo. Any type of toothpaste will work, but opaque toothpaste is the most popular option.

Mix the ingredients until they’re combined. Use a toothpick, craft stick, or spoon to stir the shampoo and toothpaste together. Keep mixing until the color and texture are even.

Add a pinch of salt to the slime and stir. In this recipe, the salt is your activator, merging all the ingredients to create a shapeable goo. Use plain table salt, as chunky rock salt won't mix in very well. Stir for about a minute or until the shampoo, toothpaste, and salt are well combined. The slime will thicken and become dough-like as you stir. If your slime isn’t the right consistency, add more ingredients as you stir. More shampoo will make it slimier, and more toothpaste will make it doughier.

Play with the slime until it dries out. This slime is thick and somewhat fluffy, so you can squish it, knead it, and stretch it. When you don't want to play with it anymore, put it into a plastic container with a lid. The slime will eventually lose its elasticity, even when stored away. If this happens, no worries! Simply toss out the old slime and make a new batch.

Gooey Slime

Put 1 to 2 squirts of a 2-in-1 shampoo into a dish. This type of shampoo is thicker and slimier than others, making it a perfect base for gooier slimes. 1 to 2 squeezes of shampoo (or roughly 2 tbsp (30 mL) should be enough to get you started. Slime makers tend to use Sauve Kids for this slime recipe, but any 2-in-1 shampoo should work well. Consider picking a scented shampoo to make your slime smell amazing.

Squeeze about 1 tbsp (15 mL) of opaque toothpaste into the dish. Use half the amount of toothpaste as you did shampoo. If you want your slime to be stickier, use even less. The toothpaste, however, must be opaque as the formula works best for creating slime. The brand of toothpaste you use is up to you, but slime makers recommend using Colgate.

Stir the shampoo and toothpaste together until it’s well combined. Use a craft stick, toothpick, or spoon to mix up your slime. Keep stirring until the shampoo and toothpaste come together to form a thick, gooey consistency, which should only take about a minute or so.

Adjust the consistency of your slime if needed. If the slime is too slimy, add more toothpaste. If it’s not slimy enough, add more shampoo. Keep stirring and adding ingredients until it’s the perfect texture.

Play with the slime until it hardens. This slime clumps together. It’s icky and sticky—the perfect gooey mess! When you’re done playing with it, put it into a small plastic container with a tight-fitting lid to save for later. Eventually, the slime will harden, and you won’t be able to squish it anymore (even after storing it in an air-tight container). But you can always make more!
