Which Slime Recipe To Use?

We have several basic slime recipes that can all be used for this green glitter slime recipe. You decide which one works best for you depending on what slime activator you want to use. This allows for some flexibility depending on where you live in the world! Not everyone has access to the same ingredients!

Each of the basic slime recipes below have the full step by step photos, directions, and even videos to help you along the way!

Here we use our Liquid Starch Slime  recipe. Slime with liquid starch is one of our favorite slime recipes! We make it ALL the time because it is so quick and easy to whip up. Three simple ingredients {one is water} are all you need. Add color, glitter, sequins, and then you are done!

Where do I buy liquid starch?

We pick up our liquid starch in the grocery store! Check the laundry detergent aisle and look for the bottles marked starch. Ours is Linit Starch (brand). You might also see Sta-Flo as a popular option. You can also find it on Amazon, Walmart, Target, and even craft stores.

But what if I don’t have liquid starch available to me?

This is a pretty common question from those who live outside of the United States, and we do have some alternatives to share with you. Click on the link to see if any of these will work! Our saline solution slime recipe also works well for Australian, Canadian and UK readers.

Now if you don’t want to use liquid starch, you can absolutely test out one of our other basic recipes using saline solution or borax powder. We have tested all these recipes with equal success!

NOTE: We have found that Elmer’s specialty glues tend to be a bit stickier than Elmer’s regular clear or white glue, and so for this type of glue we always prefer our 2 ingredients basic glitter slime recipe.


Green Glitter Slime Recipe

I always encourage my readers to read through our recommended slime supplies list and How To Fix Slime Guide before making slime for the first time. Learning how to stock your pantry with the best slime ingredients is easy!


  • 1/2 Cup of Clear Or White PVA School Glue
  • 1/4 Cup of Liquid Starch
  • 1/2 Cup of Water
  • Food coloring, confetti, glitter, and other fun mix-ins


STEP 1:  In a bowl mix 1/2 cup water and 1/2 cup of glue (mix 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!

You can never add too much glitter! Mix the glitter and confetti and color into the glue and water mixture.

STEP 3: Pour in 1/4 cup of liquid starch. You will see the slime immediately start to form. Keep stirring until you have a gooey blob of slime. The liquid should be gone!

STEP 4:  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 MAKING TIP:   We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve its consistency. The trick with liquid starch slime is to put a few drops of the liquid starch 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 liquid starch reduces the stickiness, and it will eventually create a stiffer slime.

You will love how easy and stretchy this St Patrick’s Day 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?

The Science Behind Slime

What’s the slime science all about? The borate ions in the slime activators (sodium borate, borax powder, or boric acid) mix with the PVA (polyvinyl acetate) glue and forms this cool stretchy substance. This is called cross-linking!

The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state. Until…

You add the borate ions to the mixture,  and it then starts to connect these long strands together. They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubberier like slime! Slime is a polymer.

Picture the difference between wet spaghetti and leftover spaghetti the next day. As the slime forms, the tangled molecule strands are much like the clump of spaghetti!

Is slime a liquid or solid?

We call it a Non-Newtonian fluid because it’s a little bit of both! Experiment with making the slime more or less viscous with varying amounts of foam beads. Can you change the density?

Did you know that slime aligns with the Next Generation Science Standards (NGSS)?

It does and that means you can use slime making activities to explore states of matter and its interactions. Find out more below…

  1. What great Slime for St. Patrick’s Day! Thanks for allowing me to share in my St. Patrick’s Day roundup 🙂

  2. This is a difficult website to get a recipe from. Is the recipe in one of the highlighted links or is it below ?Neither sometimes so it’s a huge time waster. you scroll and scroll through heaps of ads and photos that lead you nowhere. There is not a clear place to click to get a recipe, there is so much highlighted that it’s a time waster. if you do a download, you’re taken on a commercial journey through all kinds of sites. All I want is the recipe for each type of slime. Is that so hard? isn’t that what this site is meant to be about?? And when you click on a recipe, it STILL doesn’t give you that> this is too commercial especially since this is purporting to be a site for kids to learn stuff. So frustrating.
