Materials for Grinch Slime

• 2 cups green glitter glue
• 1 to 2 cups liquid starch

Optional additions:

• Holiday extract or cinnamon extract
• Extra glitter
• Heart sequins
• Grinch figurines
• Holiday cookie cutters

Tip: A few drops of cinnamon or peppermint extract gives this slime a festive holiday scent that pairs perfectly with Grinch themed play.

How to Make Grinch Slime

Step 1: Add the Glue

Pour the green glitter glue into a large mixing bowl.

Step 2: Add Optional Extras

If desired, add a few drops of holiday extract, extra glitter, or heart sequins.

Stir everything together before adding the activator.

Step 3: Add the Liquid Starch

Slowly add the liquid starch while stirring.

Start with a smaller amount and continue adding more a little at a time until the slime begins to form and pull away from the bowl.

Step 4: Knead the Slime

Once the slime comes together, remove it from the bowl and knead it with clean, dry hands.

At first the slime may feel sticky or stringy. Keep kneading. The texture will become smoother and stretchier as the ingredients fully combine.

After a few minutes of kneading, you'll have soft, stretchy Grinch slime that is perfect for holiday sensory play.

Make Grinch Farts

This always gets a laugh.

Squeeze some Grinch slime into a small jar or container. As the slime pushes inside, it makes funny sounds that kids find hilarious.

We used small containers, but any small jar works well.

Glow-in-the-Dark Grinch Slime

Want to make this activity even more magical?

Add 1 teaspoon of green glow paint while mixing the glue. Then shine a blacklight over the finished slime to create glowing Grinch slime that looks incredible in a dark room.

The glow effect pairs perfectly with the bright green color and makes this activity feel extra special during Christmas movie nights and holiday parties.

You can also add heart sequins and Grinch figurines to create glowing sensory scenes inspired by the story.

A small blacklight flashlight can completely transform the experience and create an exciting new way to explore the slime.

Tips & Troubleshooting

• If your slime feels too firm, knead in a small amount of glue
• Add starch slowly because too much can make slime rubbery
• Store slime in an airtight container between play sessions
• Add glow paint for an easy glow in the dark version
• A blacklight flashlight creates the strongest glow effect
