Make our star confetti slime recipe for easy homemade slime and quick kids science and sensory play!


Liquid starch slime is one of our favorite sensory recipes! We make it ALL the time because it is so quick and easy to whip up. 3 simple ingredients {one is water} are all you need. Add color, glitter, sequins, and more!

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. You can also find liquid starch on Amazon, Walmart, Target, and even craft stores.

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

I often get asked, “Can I make my own liquid starch? The answer is no, you cannot because the slime activator (sodium borate) in the starch is crucial to the chemistry behind the slime! Additionally, you can not use spray starch!

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 slime recipes below to see if any of these will work!

Oh, and slime is science too, so don’t miss the great information on the science behind this easy slime below.  Watch our awesome slime videos and see how easy it is to make the best liquid starch slime!


We always like to include a bit of homemade slime science around here!  Slime is an excellent chemistry demonstration and kids love it too!   Mixtures, substances, polymers, cross-linking, states of matter, elasticity, and viscosity are just a few of the science concepts that can be explored with homemade slime!

What’s 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 rubbery 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!




  • 1/2 Cup PVA White Glue 
  • 1/4 cup of Liquid Starch
  • 1/2 Cup of Water
  • Star confetti


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

STEP 2: Now’s the time to mix in the star confetti! 

STEP 3: Pour in 1/4 cup of liquid starch and stir well.

You will see the slime immediately start to form and pull away from the sides of the bowl. 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 change.

SLIME MAKING TIP:   The trick with liquid starch slime is to put a few drops of the liquid starch onto your hands before picking up the slime. However, keep in mind that although adding more liquid starch reduces the stickiness, and it will eventually create a stiffer slime.
