FUN HALLOWEEN SLIME PLAY WITH BAT CONFETTI
HALLOWEEN SLIME
This easy to make Halloween slime recipe is 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!
SLIME 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 into glue/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 kneading the mixture together. You may have left over borax solution.
STEP 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!

This looks so cool! Now I need spiders & bats! LOL
I love this!!!
Did I miss the recipe & directions??
The link to the recipe would not open. Could you publish the recipe or the link to the site? My kids loved playing with slime and I would like to make some for my grandkids.
Love new recipes would love to know how much ingredient it needs for the slime.
Great ideas!
This will be great to make with the grandkids.
Love your ideas…wasn’t sure of the amounts of the ingredients of bat slime!!,
Please click through the link that takes you to the recipe. It’s not mine to share exactly!
Please check in the top of the post. I link to the exact recipe as it isn’t an original!
I am sorry it works for me! Please try again. I am afraid it would be unethical for me to post directly as it is not my original!
Yes you must click through the ink I provided which is in the paragraph above the ingredients! It’s not my original to share!
Thanks George!
Aw lots of fun!
The link will not open. I have all of the ingredients and can’t do the project because the link isn’t working, as stated above in someone’s earlier post.
I have checked and re-checked and have asked several people to open it for me. I have re stated it so please try the click here exact recipe. http://www.hometrainingtools.com/a/slime-recipes-project is the link.
Enhoraƅuena! y agradeϲido!
He de subrayar que tu entrada en el web page me ha Ñ•ido siceramente beneficioso!
Love this idea! Where did you purchase the little bats in the slime? Thanks!
The confetti was from target I believe!
The link won’t work for me either. It goes to the site and then the screen goes white and won’t load.
I’m doing this as a bday party craft any idea of how much it makes? is the pictured amount 1 batch? I’m thinking of splitting the recipe up for small batches of slime.
Can I mix food coloring in? Green, for example to make it clear green?
I bet it would work but haven’t tried it!
Darnit. My phone won’t open the links either. I bought the stuff to make it but not exactly sure the exact amounts I need.
I can’t wait to try it! I want to make it 1 1/2 weeks before Halloween for my sons class, but I don’t want it to go bad. Do you know how long it will last if I make it in advance?
just did clear glue with green food coloring…worked perfect! it’s still clear but green…I actually put a drop of glue in the bottle and shook it up that way. What a workout for 12 bottles of glue 🙂
Awesome! We will actually be making a green too soon!
Sorry for the late reply. I am not positive how long it will last but certainly we have had ours for a week. I am doing a test now.
It is one batch. You might get two-3 out of one!
I am sorry I think I caused them too much traffic! 1/2c water mixed with 1/2 c glue and then mix into 1tsp of borax diluted with 1c of water!
Can any of these slimes be preserved and re-played with? If so what kind of sealed container would work best?
I have used a regular old dollar store tupperware container and have kept our current one for four weeks now!
Reusable plastic containers are perfect. Ours last for a month unless they get really dirty.
I wanted to let you know that I love your unique slime idea, and I am linking to it in my post publishing tomorrow morning. http://freshlymessy.com/two-valuable-ways-to-expand-a-preschoolers-vocabulary-without-reading/ While I didn’t use the exact same recipe or idea, I wanted to include your website as I find it a valuable supplemental idea to my post. Is it okay with you for me to link to you? If you’d rather me not share your content, please let me know so that I may remove it appropriately: [email protected]
Yes of course!Thank you.
Yoooo! Lol, You can try spider-Slime your own.
