This spooky spider Halloween slime recipe couldn’t be easier to make. With only two ingredients (no Borax!) it’s easy and affordable enough to make for a group which makes it perfect for class Halloween goody bags or Halloween party favors.

Spider Halloween Slime Recipe

Basic Slime Ingredients

• White School Glue – Go ahead and get a gallon. You can find it on Amazon for cheap, and it works just as well as Elmer’s.
• Liquid Starch – The laundry section of any grocery or big box store should have this. If not, Amazon to the rescue.
• Spiders – I purchased a small pack of these at Walmart in the Halloween section for 98 cents. If you can’t find any, or are making this spider Halloween slime recipe outside the Halloween season, you can buy the exact same ones on Amazon but they’ll be in bulk.

That’s it!

Halloween Spider Slime Recipe Directions

This isn’t going to be an exact science so if you’re precise like me (I totally get it), you’ll have to learn to learn to go with the flow to make good slime.

1. Start by placing approximately (I know, I know) 2/3 cup glue into a bowl
2. Add approximately (don’t shoot me) 1/4 liquid starch and stir with a spatula
3. At this point, it’s best to get hands-on by taking the slime out of the bowl and working it with your hands.

Is the slime to sticky? Add more starch. Is the slime too goopy/stringy? Add more glue.

Keep mixing the slime with your hands until it’s just right. For us that means not a single speck of slime sticks to your hands when you play with it. Sweet T cannot handle it sticking to her, so we don’t shy away from the starch. You’ll know if you’ve added too much because the slime with be wet and running through your fingers kind of like a leak you are trying to contain with your hands. No worries if that happens. Just add more glue!

Worst case scenario, you wind up making a larger quantity of slime than you intended and you can just split it in halve an reserve the rest for another recipe like the Jingle Bell Slime I’ll be posting soon.

These pictures are from my very first attempt at slime making, so rest assured you can get perfect slime on your first try too just by getting your hands a little sticky.

Ahhh. That is stretchy perfection and my hands are clean. I love how this basic slime recipe even looks kind of spider-webby without even trying.

Now we’re ready to add the spiders!

If you’re giving it as a gift, I like to mix a few into the slime and then add a few to the top for the recipient to mix in. It looks prettier that way.

Now that you’ve made this spider Halloween slime recipe there will be no stopping you. It’s kind of an addiction. Aren’t you glad you bought the gallon size glue?
