Introduction
If there’s one thing that defines Ghostbusters’ chaotic encounters with the supernatural, it’s that neon green, glowing goo: ecto-plasmic slime. Whether dripping off Slimer or oozing from haunted toasters, it gave the ghostly world a visceral, messy realism.
In this kid-friendly, cosplay-approved DIY slime tutorial, we’ll show you how to make your own glow-in-the-dark slime inspired by Ghostbusters—complete with eerie glow, drippy texture, and ghost-chasing fun.
Materials & Tools You’ll Need
⚠️ Non-toxic, UV-reactive, and perfect for props, parties, or just a slimy afternoon.
Most of these ingredients are easy to find at crft stores, online, or even in your own kitchen.
Main Slime Ingredients
- ½ cup Clear School Glue (PVA Glue) – Base of the slime

👻 Step-by-Step: How to Make Ghostbusters Glow Slime
Step 1: Mixing the Slime Base
- Pour the Glue Into a Bowl
- Use 1/2 cup of clear PVA glue (or more for a bigger batch).
If you want extra stretchiness, mix in 1 tablespoon of water.
- Use 1/2 cup of clear PVA glue (or more for a bigger batch).
- Add Glow-in-the-Dark Pigment
- Stir in 1-2 teaspoons of glow powder (or a few drops of glow paint).
- If using highlighter ink, break open the highlighter and squeeze the ink into the glue.
- Add Green Color
- Start with 3-4 drops of neon green food coloring or acrylic paint.
- Mix well until you get a Ghostbusters-style ectoplasm green.
Step 2: Activating the Slime (Making It Gooey!)
Now, we need to turn this into actual slime! Choose one of the following methods:
Method 1: Using Borax Solution
- Dissolve 1 teaspoon of borax in 1 cup of warm water.
- Slowly add the borax solution into the glue mixture while stirring.
- Keep stirring until the slime starts forming and pulling away from the bowl.
- Knead the slime with your hands until it’s stretchy and gooey.
Method 2: Using Contact Lens Solution + Baking Soda
- Add ½ teaspoon of baking soda to your glue mixture and mix well.
- Add 1-2 tablespoons of contact lens solution (it must contain boric acid).
- Stir until the slime thickens and starts clumping together.
- Knead with your hands to make it smooth and stretchy.
Step 3: Adjusting the Slime’s Consistency
- For thicker slime (more gooey like the movie) –
- Add a teaspoon of cornstarch and knead it in.
- For runnier, drippier slime – Add a little more water (a few drops at a time).
- For extra stickiness (great for sliming props) – Add a little extra glue.
Step 4: Making It Glow!
- Charge your glow slime
- If using glow powder or glow paint, place the slime under a bright light for 30-60 seconds.
- If using highlighter ink, hold it under a UV/blacklight for instant glowing.
- Test the Glow Effect
- Turn off the lights and shine a blacklight on your slime.
- You should see an eerie ecto-plasmic green glow!
Step 5: Storing & Using Your Ecto-Slime
- Store in an airtight container or plastic bag to keep it fresh for weeks.
- If the slime dries out, add a few drops of water and knead it to restore texture.
- Avoid getting it on fabric or carpet—it can be messy!

👻 Ghostbusters FX History: Slime on Set
Did you know? The original Ghostbusters used meticulously crafted practical slime made from methylcellulose (a food thickener) and green-tinted goop. It was applied with air compressors, tubing, and even dumped by the bucketful for that iconic "sliming" look.
Slimer’s gooey trail was often real slime on miniatures or physical props.
Special UV-reactive variants were used for glowing FX.
For Ghostbusters II, “psychomagnetheric slime” was upgraded with more shimmer and glow effects, filmed under blacklight.
These old-school tricks still hold up—and now, you’re recreating that FX magic right at home.
