Make Your Unicorn Slime
It’s time for the glittery main event, where little hands transform simple ingredients into magical unicorn slime!
What You’ll Need:
- Elmer’s clear glue (5 fl oz / 147 ml per child)
- Elmer’s Magical Liquid (2.3 fl oz / 68 ml per child)
- White iridescent glitter
- Pink pastel glitter
- Cotton candy or marshmallow candle scent
- Mixing bowls
- Mixing spoons or sticks
- Unicorn horn containers
- Clear screw-top containers for safe transport of slime
💡 Tip: Swap clear glue for glitter glue to get sparkling slime without the glitter chaos!




Instructions:
1. Mix the Slime Base
Empty one bottle of clear glue into a mixing bowl. This is your crystal-clear canvas, ready for a little unicorn alchemy.
2. Sprinkle the Stardust
Add white iridescent and pink glitter. Stir slowly and watch tiny galaxies swirl through your slime base.
3. Sweeten the Slime
Drop in a few drops of cotton candy or marshmallow scent. Give it a gentle stir until your slime smells like it drifted out of a fairy floss cloud.
4. Awaken the Magic
Slowly pour in the Magical Liquid while stirring. Keep mixing as the slime begins to gather itself and pull away from the bowl like it has a mind of its own.
5. Stretch and Sparkle
Once it’s no longer sticky, knead and stretch the slime until it’s smooth, glossy, and satisfyingly stretchy.
6. Crown Your Creation
Place your slime into unicorn horn containers. It’s not just slime, it’s now unicorn treasure.
💡 Tip: For younger children, prepare the slime base ahead of time and let them focus on adding glitter, scent and charms!




Whimsical Unicorn Games
Keep the magic going with unicorn-themed games kids will love!
- Pass the Rainbow: Sit in a circle and pass a plush rainbow while music plays. When the music stops, the player holding it is out. The last player remaining wins a prize!
- Unicorn Treasure Hunt: Hide unicorn-themed clues around the party space, each leading to the next, until kids find the final treasure chest filled with sparkly surprises.
- Pin the Horn on the Unicorn: Blindfold each child and have them try to stick a glittery unicorn horn onto a large unicorn poster. The player who gets their horn closest to the correct spot wins a sparkly prize.
💡 Tip: Set up a Unicorn Photo Booth with flower crowns, unicorn horns and pastel props for dreamy photos.

Unicorn Slime Party FAQs
What age group is this activity best for?
Perfect for ages 5–12. Younger children may need assistance with mixing the slime, while older kids can manage independently.
How long does slime-making take?
Plan for 30–45 minutes from start to finish. Add extra activity stations or games to extend the fun!
Is the slime safe for kids?
Yes! Elmer’s glue and slime activator are kid-safe, but adult supervision is recommended when using scents, glitter, or tiny charms.
Do I need to prep slime in advance?
