What to Expect

Here's exactly what happens at your Cosmic Slime party

Book in two minutes. We show up 15 minutes early with a fully-stocked slime cart. The kids make custom slime for 60–90 minutes. We clean everything up. You enjoy the party.

03
60–90 minutes of fun

Guided slime-making

Every kid makes their own custom slime, start to finish. We guide them through every step — choosing colors, mixing activators, adding glitter and charms — and clean up any spills along the way.

Cosmic Slime brings

  • Every supply — glue, activators, colors, glitter, scents, charms
  • Hands-on instruction for each kid, paced to your group
  • One custom slime per guest, made from start to finish
  • All cleanup of spills, drips, and stray glitter mid-party

You provide

  • The kids and any grown-ups you want in the room
  • Light supervision (we run the activity, you enjoy the moment)
  • Cameras ready — this is the photo-op part of the day
04
While the kids say goodbye

Once the slime-making wraps up and the kids are packing out, we break everything down. By the time the last guest leaves, the activity area is clean and the cart is on its way out.

Cosmic Slime brings

  • Full station breakdown and packing
  • Surface wipe-down of tables and floors
  • A packed cart ready to roll out
  • A spotless space for you to enjoy after the party

You provide

  • Showing the host to the door

  • Zero cleanup on your end
05
