How to Make Ghost Slime
Materials:
To make the slime:
To decorate the ghost:
Instructions:
Step 1: Find what you need
- Gather your supplies and materials.
Step 2: Mix the first ingredients
- Pour 1/2 cup of white glue into a bowl.
- Add 1 teaspoon of baking soda and stir to combine.
- Then, to make your ghost slime glow, add glow in the dark acrylic paint. We added 2 good squeezes (probably about 1 to 2 teaspoons).Again, stir to combine.
Step 3: Activate the slime and mix
- To activate the slime, add 2-1/4 teaspoons of contact lens solution.
- Stir the slime until it becomes thick and pulls away from the bowl.
- When you can’t stir the slime any more, pick it up and knead it with your hands. It might be a bit sticky at first, but after stretching the slime for a minute or so, it’ll become nice and smooth.
Step 4: Create a ghost friend and watch it glow
- To make your ghost slime extra ghost-like you’ll need a plastic (or glass) cup and a scrap piece of black craft foam.
- Cut eyes and a mouth for your ghost from the craft foam. Detail scissors work well to cut out the mouth, and the round eyes were made with a one hole punch.
- Your ghost slime is complete!Place the slime over the bottom of the cup and let it ooze down. Add the foam face to the side, and then turn off the lights and watch your ghost slime glow!
Helpful Tips:
- Switch up the ghost face: You can use googly eyes or cut the face from cardstock or construction paper. We liked craft foam best because it doesn’t get ruined in the slime and can be reused again and again.
- Adjust the stretchiness: Add contact solution a little at a time. This recipe makes a slime that’s super stretchy without being too sticky, but if you prefer a runnier slime, try using just 2 teaspoons of contact solution.

How can I make my ghost slime glow in the dark?
The easiest way to make glow in the dark slime is to mix in glow in the dark paint, which you can find at most craft stores.
You can also use glow in the dark pigment powder. It doesn’t mix in quite as smoothly, but that uneven texture adds to the spooky, ghostly effect!

What’s the best glue for a ghost slime recipe?
White school glue is perfect for ghost slime, since it gives you that bright white ghostly colour. You can also experiment with clear glue for a more translucent ghost effect.

How can I play with my glowing ghost slime?
The white glow-in-the-dark slime is already ghostly on its own, but you can make it even more fun, using a couple simple ideas.
Try draping the slime over the bottom of a plastic cup to create a standing 3D ghost, then add a foam face. Or, add the face pieces while playing to make the ghosts come alive right in your hands or on the table. As you stretch the slime it’ll move the ghost’s face!

This ghost slime is such a fun mix of creepy and cute. It’s soft and stretchy, and the glow factor just adds to the Halloween magic. With a simple ghost face and a little imagination, you can create a whole ghost story while you play, squishing and stretching the slime into different shapes.
Whether you’re making this ghost slime recipe for a Halloween party, a classroom activity, or just some hands-on fun at home, this DIY slime is sure to be a hit. It’s oozy, glowing, and delightfully ghostly — the perfect DIY Halloween craft for the spooky season!
