HALLOWEEN SLIME
This easy to make Halloween slime recipeis the perfect party activity or party favor for kids. Plus it’s fun to whip up and put together with really simple ingredients that you can pick up at the grocery store too.
Packed into little plastic condiment containers, Halloween-themed candy-free slime party favor ideas are great to make and take or hand out at the end of the night.
We made this Halloween theme slime recipe with clear glue and fun bat confetti!
What else can you pack into your Halloween slime? Just check out the Halloween party aisle of your local dollar store, party store, or craft store. They make a confetti (or sometimes called table scatter) for every occasion. I have seen an assortment for Halloween including bats, jack o’lanterns, ghosts, and more!
This slime recipe uses a different slime activator and we add color!
PinSLIME SCIENCE AND CHEMISTRY
We always like to include a bit of homemade slime science around here, and that’s perfect for exploring chemistry with a fun fall theme. 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 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 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…
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 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!

HALLOWEEN BAT SLIME RECIPE
The base for this Halloween theme slime uses one of our most basic slime recipes (borax slime recipe) which is clear glue, water, and borax powder. HOWEVER: If you prefer to use our saline solution recipe as seen in the video above, that works too! You will not get a crystal clear slime, but you can add food coloring.
SUPPLIES:
- 1/2 cup of PVA Clear School Glue
- 1/2 cup of water
- Borax Solution: 1/2 cup of warm water mixed with 1/4 tsp of borax powder until dissolved.
- Bat Confetti or other add ins as desired
METHOD:
STEP 1: Dissolve 1/4 teaspoon of borax powder into 1/2 cup of warm water in one of the three bowls. Mix this thoroughly.
BORAX SLIME NOTE: We have recently tinkered with our recipe and found that for a better oozing slime 1/4 tsp of powder is best (if using clear glue always use 1/4 tsp). If you like a firmer slime and are using white glue, we experimented with 1/2 tsp and 1 tsp. 1 tsp makes a much firmer putty slime.
STEP 2: In the second bowl measure out about 1/2 cup of clear glue and mix with 1/2 cup of water until well mixed
STEP 3: Pour borax/water mixture intoglue/water mixture and stir it up!
STEP 4: You will see it come together right away.It will seem stringy and clumpy, but that’s ok! Remove from bowl.
STEP 5: Spend a few minutes kneadingthe mixture together. You may have left over borax solution.
PinSTEP 6: Store in clean container with cover. I love the deli style plastic food storage containers.
TIP: If your slime still feels too sticky, you may need a few more drops of borax solution. You can always add but you can’t take away. Adding to much activator will temporarily make the slime less sticky but will also make the slime more rubbery and brittle over time. Knead, knead, and knead some more!
