How to Make Slime with Shampoo

Using Shampoo and Cornstarch

Pour ½ cup (120 milliliters) of shampoo into a bowl. Thicker shampoos will give you better results. Choose a color and a fragrance that you like.

Stir in some color or glitter, if desired. If the shampoo is white or clear, you could add a few drops of liquid food coloring into the bowl. If you want glittery slime, add some glitter. Stir everything together with a spoon.

Add 2¼ cups (280 grams) of cornstarch. Give it a stir with your spoon. If you want a thicker slime, you are done. If you want a runnier, gooier slime, read on! If you don't have cornstarch where you live, look for corn flour instead.

Stir in the water 1 tablespoon (15 milliliters) at a time. You may need up to 6 tablespoons (90 milliliters) of water. The more water you add, the runnier your slime will be. If you want something more dough-like, you might not need much water, if at all.

Knead the slime by hand. At one point, the slime will have picked up all the water and cornstarch it can. Once that happens, your slime is done and ready to play with! Scoop it out of its bowl, and let it run through your fingers. Store the slime in an airtight container once you are done playing with it. You may need to add 1/4 teaspoon of water to the slime to refresh it the next day.

Using Shampoo and Salt

Squeeze some thick shampoo into a bowl. You can use any type of shampoo you want, but thicker shampoos work better. Choose a color and fragrance that you like.

Stir in some body wash, if desired. This will help make your slime thicker. Use equal amounts of shampoo and body wash. Stir the two together until there are no more streaks. Make sure that your body wash and shampoo are similar colors, or your slime will end up muddy.

Stir in some salt until the shampoo thickens. There is no set amount for the salt, as each brand of shampoo reacts differently with it. Simply add in a pinch of salt, then give the slime a stir. Keep adding salt and stirring until the shampoo turns into a glob.

Freeze the shampoo for 15 minutes. Once you have your glob, place the bowl into the freezer. Leave it there for 15 minutes.

Play with the slime. Once the freezing time is up, the slime will have set and is ready to play with! When you are done playing with it, put it into an airtight container. You may need to re-freeze (15 minutes) it if it becomes too runny.

Using Shampoo and Toothpaste

Squeeze some 2-in-1 shampoo into a mixing bowl. The 2-in-1 combo shampoos seem to work the best. Choose a fragrance that goes well with mint. You can try plain shampoo as well, but make sure that it is thick.

Add in some toothpaste. You can use white toothpaste or gel toothpaste, it does not matter. You will need to use the same amount of toothpaste as you did shampoo.

Stir the two together with a spoon. Keep stirring until the color is consistent and no streaks remain. As you stir, the shampoo and toothpaste will come together and form a putty-like slime.

Adjust the consistency, if needed. If the slime is too thick for you, you can add in some more shampoo. If it is too thin, try some more toothpaste. Make your addition, then stir it in well.

Play with the slime. This slime is not quite as gooey as the store-bought kind, but it is fun to poke and prod. When you are done playing with it, scoop it into an airtight container.
