How to make Slime Activator with Salt : SALINE SOLUTION 

This slime activator is also commonly used as a contact solution, but I highly recommend picking up the lesser expensive saline solution instead.

Also, on our slime activators list is salt. So how to make slime activator with salt. You have to make a saline solution first by mixing salt with water. To make this saline solution use one cup of water and half a teaspoon of salt and place this in a pan. Boil this for approximately fifteen minutes and keep the pan lid on to avoid evaporation. You will then need to allow the pan to cool until it is at room temperature. Finally, carefully pour this solution into a bottle and jar which has a lid. You are now ready to start combining it with the glue to make some gooey fun stuff!

How to make Slime Activator with Salt – Salt is a good option as an activator for slime as it is readily available and it is also cheap to purchase. The volume of salt that you can purchase can produce a large quantity of slime which is useful if you need to make a large amount or if you plan to make it on a few occasions.



  • 1/2 cup Clear or White PVA School Glue
  • 1 tablespoon Saline Solution (must contain boric acid and sodium borate)
  • 1/2 cup of Water
  • 1/4-1/2 tsp Baking Soda
  • Food coloring, confetti, glitter, and other fun mix-ins (CHANGE FOR RECIPE)

How to make Slime Activator with Salt


STEP 1:  In a bowl mix 1/2 cup water and 1/2 cup of glue well to combine completely.

STEP 2: Now’s the time to add (color, glitter, or confetti)! Remember when you add color to white glue, the color will be lighter. Use clear glue for jewel toned colors!


STEP 3: Stir in 1/4- 1/2 tsp baking soda.

Baking soda helps to firm and form the slime. You can play around with how much you add but we prefer between 1/4 and 1/2 tsp per batch. I get asked all the time why do you need baking soda for slime. Baking soda helps to improve the firmness of the slime. You can experiment with your own ratios!

This slime recipe is also called BAKING SODA SLIME!

STEP 4: Mix in 1 tbsp saline solution and stir until slime forms and pulls away from sides of the bowl.   This is exactly how much you will need with the Target Sensitive Eyes brand, but other brands may differ slightly!

If your slime still feels too sticky, you may need a few more drops of saline solution. As I mentioned above, start by squirting a few drops of the solution onto your hands and kneading your slime longer. You can always add but you can’t take away.  Saline solution is preferred over contact solution.

STEP 5:  Start kneading your slime! It will appear stringy at first but just work it around with your hands and you will notice the consistency changes. You can also put it in a clean container and set it aside for 3 minutes, and you will also notice the change in consistency!

SLIME TIP:   We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve its consistency. The trick with this slime is to put a few drops of the saline soluti9n onto your hands before picking up the slime.

You can knead the slime in the bowl before you pick it up as well. This slime is stretchy but can be stickier. However, keep in mind that although adding more activator (saline solution) reduces the stickiness, and it will eventually create a stiffer slime.


You will love how easy and stretchy this saline slime is to make, and play with too!  Once you have your desired slime consistency, time to have fun!  How big of a stretch can you get without the slime breaking?

SLIME TIPS AND TRICKS on How to make Slime Activator with Salt

  • Baking soda helps to firm and form the slime.  You can experiment with your own ratios!
  • BAKING SODA SLIME TIP: Clear glue slime usually doesn’t need quite as much baking soda as white glue slime!
  • The saline solution is the slime activator and helps the slime to get its rubbery texture! Be careful, adding too much saline solution can make for a slime that’s too stiff and not stretchy!
  • Give this slime a fast stir to activate the mixture. You will notice the thickness change as you stir it.  You will also notice the volume of your mixture changes as you whip it up.
  • Slime is awesome for tactile sensory play, but make sure to wash hands and surfaces after making and playing with slime.
  • Make a few batches in different colors and swirl them together as shown in the cover photo or below! Think of what other color combinations your kids would enjoy. Slime making is only limited by the imagination of the hands creating it!
