A hands-on

slime experience

+ custom party favor in one

We bring the Slime Bar. Each guest creates their dream slime and takes home a party favor they made themselves.

how does it work?

…Like an ice cream bar, but for SLIME!

The Slime Bar is a fully mobile, interactive party-favor experience.

We come to you, pop up our bar and guide each guest through creating a personalized slime to take home.

1. Choose Your Package

Choose the package that best fits the number of guests who will be creating slime. Each package includes a set number of custom slime creations.

2. Choose Your Flavors

We’ll send you our slime “flavor menu,” and you choose your favorites. We bring everything needed for the full experience!

3. We Bring the Slime Bar to You

On the day of your event, we’ll arrive early to set up the bar at your home or venue. All we need is a designated space—we take care of the rest!

4. Let the Slime Begin!

Each guest chooses a slime flavor and customizes it with colorful mix-ins, glitter, charms and more. Our Slime Bar attendant guides the experience, scoops the slime and keeps everything running smoothly.

5. We Handle the Cleanup

Once the included slime creations are complete, each participating guest takes home their personalized slime and our attendant begins packing up. No slime prep or cleanup for you!
