How to make Slime Activator with Salt – This is our number one favorite on the slime activator list because it makes an awesome stretchy slime. It’s also more easily available for UK, Australian and Canadian residents.

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!

Best Slime Activator

Which slime activator works best?

Slime activators are the key to making your slime stick together. Whenever you want to make slime, you’ll need an activator so that your ingredients will glue together rather than sliding off.

We’ve looked at a few different options, and we believe that each of the following three activators will lead to a great end result:

1) Borax Powder – One teaspoon borax powder mixed with one cup of warm water can create about 10 cups of slime. You can also use powdered laundry detergent in place of borax powder as well! Borax is abrasive so handle with care.

2) Egg Whites – One egg white mixed with two cups of warm water can make between 2 and 4 cups of slime, depending on your “loaf-size.” You can make about 10 loaves with a whole egg.

3) Gelatin – We suggest using unflavored gelatin powder. Two teaspoons of gelatin per cup of water will create enough slime that the two ingredients alone will not keep it together very long! Just add some borax or baking soda to your slime and you’re all set.

Which slime activator is the best? We suggest borax as it’s cheap and easy to get your hands on. For a great end result, just mix one teaspoon of borax powder with one cup of warm water.

To use the slime activator, simply stir it into your ingredients and allow them to sit for a few minutes until the glueiness of your slime has increased by at least 100%. If you’re having trouble getting your ingredients to stick together, consider dusting some cornstarch over them. This will help keep them together!

The only thing that you’ll want to watch out for with borax is that it can be pretty abrasive. In fact, it will scratch glass and remove the paint from nails! If you have sensitive skin, you should also be wary of using borax. It might irritate your skin.

How to make Borax Slime Activator

Borax doesn’t react with anything other than water and soap. That means that it can be used in slime without making it slimy on the outside or destroying the colors of other ingredients.

Borax is also non-toxic to humans — so if you have kids who are into cooking with slime, this one’s better for them than food colouring (which can be potentially toxic). All told, this ingredient should make it easy to do things like put together a snowman out of slime or create all of your favorite characters from Pixar movies out of goo.

Borax slime ingredients

1/2 cup of cornstarch
1/2 teaspoon of borax (read the directions on the bottle!)
Add all ingredients to a bowl and knead ’em together with your hands till it’s good and smooth. Just make sure to re-knead it until it’s nice and smooth. If you don’t have cornstarch, you can use plain old flour instead. Add more cornstarch or flour if necessary to thicken the slime up.
Pour into a bowl, cover with plastic wrap and turn over so that plastic is touching slime — so that whatever gets absorbed by the plastic won’t dry out before you use it.
Wait for your slime to thicken up and be ready to use!
What can you do with slime?
Slime is fun for kids of all ages. Think about how it feels when you drip a bit of water from the faucet, and it runs down your hand or arm. What does that feel like? Try pouring a little water into some Borax Slime, and see what happens. It might not be all that much different than pouring water all over your hand or arm.
This is an example of how slimy Borax Slime looks before it’s activated
To activate Borax Slime, add 1/4 cup of warm tap water. The borax, water, and cornstarch should react together to make a goo.
You can now add any colour you want to your slime by mixing in food colouring.
The last step is to knead the slime in your hands until it’s nice and smooth before letting it dry.
If you want the coloured slime to stay smooth as it dries, mix in more food coloring! You can use half a teaspoon of food colouring for every 1/4 cup of Borax Slime you make. Just know that colours will change as they dry.

Basic slime recipe

1. Combine glue and water in a bowl.
2. Add food coloring, dish soap, and borax to the mixture and mix it around until it becomes thick and goopy
3. Add a few drops of cooking oil to the mixture
4. Get your hands, or other object, in the slime and knead it until there are no longer any visible chunks of glue
5. The slime will start to become hard after a few minutes
6. Squeeze the excess borax out of the slime, so it doesn’t make your hands sticky
7. Store in an airtight container for up to 5 days.

Slime Without Activator Recipe

If you’re looking for something to spice up your slime, why not try our recipe for slime without activator? All you need is glue, shaving cream, food coloring, and water.

To create a batch of slime without activators:
1) Pour ½ cup of glue in a bowl. Add ¼ cup of shaving cream and a few drops of food coloring. Mix it all together with water from the tap until it reaches the consistency that you want.

2) You may need to work in batches as this ratio is not very sticky. A good thickness will stick to itself when you touch one piece to another.

3) Enjoy!

Edible Slime Recipe

Edible slime is a new and popular cooking trend for kids and adults alike. It’s a great way to lead into kitchen science, chemistry, or even the biochemistry of baking! All you need is two ingredients: 1 packet of unflavored gelatin and 1/4 cup (4 tablespoons) of sugar. For an extra boost of fun in the kitchen, try adding food coloring to either one or both ingredients.

We’ve used the recipe below to create our edible slime. This recipe yields a mixture that is thick enough to hold its shape when added to water while still maintaining its initial slime-like appearance. You can also adjust the consistency of the slime by adding more passion fruit or cornstarch if you find that you need more or less gelatin to get the consistency you desire.

Before you begin to make your slime, you may want to test the consistency and appearance of your edible slime. Simply add a couple of drops of water to a small amount of gelatin or cornstarch. If you find that the mixture is too runny (almost like water), add more gelatin. If you find it difficult to form the slime into interesting shapes, add more cornstarch.


1 packet of unflavored gelatin (about 2 tbsp.)  (found in most grocery stores in the same aisle as Jello-O) 1/4 cup (4 tbs.) sugar 1/2 cup passion fruit juice or corn syrup Instructions: 1. In a medium-size bowl, mix the gelatin and sugar according to the package directions. Note: our mixture was too thin, so we added some cornstarch to thicken it up a little.

2. In a small saucepan over medium heat, bring passion fruit juice or corn syrup to a simmer. When juices are simmering, add the hot mixture to your gelatin mixture and stir until completely dissolved (be careful not to burn yourself).

3. Refrigerate until completely cool; if necessary, refrigerate for about 30 minutes in order to harden the slime again before playing with it!

4. Enjoy!
