Spooky Slime – Easy Halloween DIY


It’s really quite hilarious that I’m over here, like, “I know! I’ll do a Halloween craft for this month’s SMB post!” Because, you guys, I don’t craft. I’m just not good at it. I want to be a crafty mom, and believe me, I have tried…and failed…and tried again…and continued to fail. But you know what? I will not compare myself to others. The Lord has blessed me with other gifts and talents and He grows them in me all the time, so it’s OK. I’m at peace and will not let comparison steal my joy. One gift that has been placed within me is that I can cook. Another is that I’m kind of into science experiments, so this craft is more like one part cooking and one part science experiment. I can totally manage it, and so can you! I give to you…how to make slime!

Kiddos LOVE making this slime stuff. I do too, because it’s affordable to make, easy, the clean up is a breeze and it provides a lot of entertainment. I like to make it with my preschooler for whatever current holiday is approaching and coordinate the colors accordingly.  Since Halloween is coming up, I did orange & black slime, but green slime could become monster guts and purple could be something witchy.

To make the slime, you will need everything pictured here:   Slime Ingredients

Follow these easy steps:

  1. In a glass bowl, pour out one 4oz bottle of clear Elmer’s glue. Fill that emptied bottle with cold water and add it to the glue. Stir well to combine. I recommend a metal spoon.
  2. Add 6-8 drops of food coloring and stir.
  3. Add 1 teaspoon of glitter and stir. Go ahead and add a dash more of glitter if you feel like it.
  4. In a separate bowl, add ½ teaspoon of Borax into a ½ cup of boiling hot water. Be sure the kids don’t miss that action because it will make a little fizzy eruption that lasts for just a couple seconds. Stir the water until Borax is completely dissolved.

Here comes the cool science part.

5. Slowly pour the Borax water mixture into the colorful, glittery glue mixture while stirring. Be amazed as the whole thing starts to transform into this weird, stretchy blob.

‘The glue has an ingredient called polyvinyl acetate, which is a liquid polymer. The Borax links the polyvinyl acetate molecules to each other, creating one large, flexible polymer.” –Home Science Tools 

As it gets really thick, don’t be afraid to get your hands in there and start kneading your blob to incorporate all the water. The temperature of that boiling water cools off quickly, but still, give it a little test before you just stick your (or your little’s) hand in there.

And that’s it!  Now you have a big ol’ blob of slime. Sit back and enjoy a delicious beverage because kids are now totally entertained and amazed at your awesome mom skills.

The finished product!
The finished product!


  • The glue must be clear, and Elmer’s works best for consistency.
  • Use ultra fine glitter.
  • When not playing with slime, keep it in a ziplock bag and store in the fridge to keep it from growing mold.
  • If you’re not already using Borax around your home, there’s a ton of cool stuff it can be used for. It’s not just for laundry, but it is great for that, too!
  • Get a manicure before taking pictures of self making slime and posting on SMB.


    • Haha! It’s always a good idea to get a manicure. If you make the slime, let me know how it turns out! 🙂 xoxo, Jennie
