How to Make Slime Without Borax

Update! I saw on the Today Show how Borax can burn kids while making slime.  I was shocked at the severity of the skin burns and checked to make sure my recipe was completely safe. Which it is! To be extra cautious always have kids fully wash their hands after playing.

Whether you call it gak or slime it is still the same thing and easy to make. You might already have these simple ingredients at home! This recipe is easy and really works! (Affiliate links included in this section.)

In this recipe, the liquid starch is the slime activator.  In my other slime recipe baking soda and contact solution make the magic happen (we also add shaving cream to make it extra fluffy). Try adding more of the activator ingredients to get the desired consistency.  Be careful though…. too much will make it stiff.  First, be sure to spend plenty of time kneading the slime before adding more ingredients. Be sure to slowly add extra ingredients so the reaction will work. The slime forms slowly sometimes.

The best part it is a safe recipe.  This recipe uses liquid starch instead of borax. This is more diluted. Why? Sometimes Borax can cause skin burns, so just to be safe we opted for a different recipe! 

We can’t stop making this slimy stretchy concoction at our house. Make this super easy two-ingredient recipe with your kids knowing it is safe.  Read below for the gak recipe with step by step instructions.

Two Ingredient Slime Recipe

Mix equal parts of liquid starch and glue together. We placed 1/4 cup of liquid starch and 1/4 cup white school glue into a sandwich bag and added about 3 drops of green food coloring. We do have the best luck with Elmer’s white school glue. Using a ziplock bags makes this mess free.

Next, add in 1/4 cup glue into the bag.

Mix well for the reaction to occur. When it starts to form a solid blob, you will know it is changing into slime. This will take time, be patient and allow it to form.

There might be a bit of liquid that does not mix in, it is alright if this happens. When at this stage, it should be ready. You just need to remove the blob and discard the bag with the extra liquid.

Take it out of the bag and have fun! Slime is so mesmerizing! It is hard to keep from touching it which makes it a wonderful sensory activity.

I really hope you enjoy this homemade gak no borax recipe as much as we do.

What does liquid starch do to slime?

Glue is a liquid polymer made up of long, repeating, and identical strands. This means that the tiny molecules in the glue are in strands like a chain. When you add the liquid starch, the strands of the polymer glue hold together, giving it a slimy feel. The liquid starch contains sodium borate and acts as a cross-linker that connects all the long strands. To make slime with glue and liquid starch, mix until the combined substance becomes thicker and rubber-like slime!

Where do you buy liquid starch?

We find our liquid starch in the laundry section at the grocery store. We use Sta-flo starch like this. (affiliate link). Looking for more ways to impress your kids?  Now that you have liquid starch to create slime you can also use the liquid starch to make the coolest marbleized paper.

Slime Tips and Tricks

  • Borax is good for squishy slime, but not ideal for a long-lasting or super stretchy slime.
  • Use liquid starch when you want it to last longer.
  • Keep it in a sealed baggie or airtight container and it should last for a couple of weeks or even months. Toss it out if it grows mold or dries out.
  • Too liquidy add more glue 1 tablespoons at a time. Be sure to mix well after each Tablespoon. Remember it comes together slowly.
  • Too sticky try adding more starch 1 tablespoon at a time, again mixing well.
  • If you get slime on the carpet, clothing, or in the hair remove it with white vinegar. For clothing soak the affected area in vinegar for a minute then rub to dissolve. Wash and dry as usual.

  1. Carole, go by the recipe. You can change the consistency of the slime by adding tiny amounts of glue or liquid starch. I hope this helps.

  2. The “story ” recipe calls for an additional amount of glue where the recipe alone at the end doesn’t. Which is accurate?

  3. Nicole, I love slime with shaving cream. It makes a super fluffy slime. Here is my recipe for fluffy slime.

  4. i have 2 great grand daughters and they love to make things….thank you for your posts….

  5. Good idea… but here is another slime recipe I love! putting the 1/2 cup glue first then adding 1/3 cup of shaving cream… (this will make your slime fluffy) but don’t add more then the amount of your slime. then about however much liquid stararch you need (I just add it in in go) and i also put it into a bowl to mix it. It is way easier. And that’s how to make fluffy slime!

  6. Carole, the more you mix it the better it gets. Remove what is formed from the liquid (there will be some extra liquid) then knead, pull, stretch until you get the desired consistency. If you read the comments, some people let it sit for a minute then when they came back to it, it was a better consistency. I hope this helps.

  7. I have tried and tried to make this slim and still I can not do it,I am doing all what you say but still no good please help thank you
