Halloween Slime Recipe
Kids love this easy homemade slime recipe, which you can make with several different slime activators. Here, we show you how we use our favorite saline solution slime recipe.

Supplies:
- 1/2 cup of PVA School Clear Glue
- 1/2 cup of water
- 1/2 tsp baking soda
- Neon Food Coloring and Glitter (you can make this slime any number of Halloween colors as seen in the video above)
- 1 tbsp of saline solution (must contain boric acid and sodium borate, Target Up and Up brand is our favorite)
Instructions:
STEP 1. Start by adding the clear glue and water to a bowl and grab a mixing utensil. Mix it up.
STEP 2. Add food coloring and glitter as desired!
STEP 3. Add in your slime activator (baking soda and saline solution) to complete the chemical reaction you read about above in the science behind the slime section. If you scrolled past it, go back and read it with your kids!
STEP 4. We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve it’s consistency.
The trick with saline solution slime is to squirt a few drops of solution 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 ultra stretchy but can be stickier. However, keep in mind that although adding more solution reduces the stickiness, it will create a stiffer slime.
What Can You Add To Halloween Slime?
What can you pack into your slime? Just check out the Halloween party aisle of your local dollar store. I found these plastic eyeballs which were perfect for this slime brew. You can even use them for a simple DIY Halloween catapult!
Also, look for these fun items:
- spiders and insects in clear slime
- vampire teeth in a blood-red slime
- google eyes in white slime
- any Halloween confetti in a clear based slime with food coloring

How To Store Slime
Slime lasts quite a while! I get a lot of questions regarding how I store my slime. We use reusable containers in either plastic or glass. Make sure to keep your slime clean and it will last for several weeks.
If you want to send kids home with a bit of slime from a camp, party, or classroom project, I would suggest packages of reusable containers from the dollar store or grocery store, or even Amazon. For large groups, we have used condiment containers as seen in the pictures above!

The Science Of 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…
Very cute! Shared on my Messes & Memories facebook page.
Awesome thank you so much!
These slime eye treats are awesome. Now I wish we were having a Halloween party so I had an excuse to make them!
