Have you just picked up a fresh bag of brightly colored plastic eggs? Now what, Make Easter egg slime of course! You know you have a hundred of these eggs in a bag somewhere in the house, but somehow the lure of the $1 package of plastic eggs hits you every year! It’s totally ok with us! Why not fill them with our amazingly easy homemade slime recipes!



All of our holiday, seasonal, and unique slimes use one of our 4 basic slime recipes that are super easy to make! We make slime all the time, and these have become our go-to favorite slime making recipes.

I will always let you know which recipe we used in our photographs, but I will also tell you which of the other basic recipes will work too! Usually, you can interchange several of the recipes depending on what you have for slime supplies.

THIS SLIME: Liquid Starch Slime Recipe


  • Ingredients:
  • 1/2 cup liquid starch
  • 1/2 cup water
  • 1/2 cup clear or white school glue (PVA glue)


  1. In a mixing bowl, pour 1/2 cup of liquid starch.
  2. Add 1/2 cup of water to the liquid starch.
  3. Measure out 1/2 cup of clear or white school glue and add it to the bowl.
  4. Mix the ingredients together thoroughly using a spoon or spatula. Make sure to combine them well until you achieve a consistent texture.
  5. After mixing, you can start kneading the slime with your hands. It may be a bit sticky at first, but continue kneading until it becomes less sticky and more stretchy.

Feel free to customize your slime by adding color or glitter if desired. You can do this by incorporating food coloring, acrylic paint, or glitter into the mixture during the mixing process.

Remember that the exact measurements may vary slightly depending on the brands of the ingredients you use, so adjust as needed to achieve the desired consistency. Enjoy making and playing with your liquid starch slime!



Each of our basic slime recipes, which we use for our seasonal, unique, and holiday slimes, has its own complete slime-making page. This way, you can see a complete page dedicated to making the specific slime, including step-by-step photos and videos!

You can check out the supplies if you want to try a different recipe from what we used in this recipe. You can watch a video of each slime being made, and of course, each recipe will also have full instructions and photos showing steps.



We love our quick and easy homemade liquid starch slime recipe. We show you how you can whip up slime in no time! For this particular slime-making activity, I used half a recipe per color.

I only wanted enough to fill a few eggs. You could quickly fill a couple of eggs with each color with the batches of Easter egg slime we made.


You can also use these plastic eggs to make other cool science and STEM activities for the kids. Check out our EASTER SCIENCE collection for great ideas.

Kids love the way slime oozes and stretches too. This makes slime great for tactile sensory play from time to time. We have so many fun sensory play recipes to check out. It’s always great to combine science and play into one easy activity.

Homemade Slime Recipe Science

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

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

When you add the borate ions to the mixture, it 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 rougher like slime!

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

Is slime a liquid or solid? We call it a non-Newtonian fluid because it’s a bit of both!

Of course, the colors won’t stay separated for long, and that’s just part of the fun. We discovered this when we first made our rainbow slime. Our ocean slime is also something you must see!


Our Easter egg slime is perfect if you want something a little different to try for an Easter science activity this year.

Plus, you can use these plastic eggs for more awesome science, like our erupting eggs, egg races, and egg launchers!
