Messy Play Parties!

Looking for a birthday party that's totally unique? Or new inspiration for your playgroup? Let us bring the Messy Play to you! Messy Play parties are sensory activities for kids in groups of 10 or more children under age 8 (or older for the Slime Station party). They are currently available only in the San Francisco Bay Area.

Parties include 3-4 activities designed around a set theme, or you can choose the custom option for a theme of your choice. The parties are geared for children ages 3-8 (and older for the Slime Station). Messy Play Kits provides all the materials necessary, plus materials for set up and clean up. Everything we use is completely washable, and parties can be hosted indoors or outdoors. Don't think you have space in your home? Find a local park or playground nearby! We are based in the San Francisco Bay Area and will travel to parties within 100 miles (further for special requests).


Messy Play Standard Parties cost $25/child plus a flat transportation fee that depends on your location ($30-50). This price includes all materials and activities, party facilitation by a Messy Play instructor, all set up and clean up costs. Party favors can be purchased for an additional fee (listed below). 

Custom parties begin at the same price, plus an additional $50+ depending on the customization required. We can match any theme for any child, be it a Bird Party, a Spooky Dinosaur party, a Train theme, a Science theme, or whatever your child wants!

      What do you get in a party?

      • Materials for 3-4 activities- choose from a standard theme or custom theme above
      • Full set up and clean up provided by your Messy Play instructor
      • Optional party favors for each child
      • Up to one hour of activity time, depending on ages and number of children

      What do I need to provide or tell the other parents in advance?

      • Messy Play staff are not childcare, so they will facilitate the activities but not be responsible for supervising individual children. (Childcare is available at an additional cost.)
      • All materials are washable, but they can be messy! Chose the party with a messiness level you feel comfortable with, and let the other parents know what to expect! Painting can be very messy for toddlers but less so for 8 yr olds.
      • We suggest you let families know in advance that Messy Play activities will be happening, so they can dress their children appropriately.
