FAQ's
Great question! For birthday parties, only the kids making slime are counted as guests—adults and guardians who aren’t participating can attend at no extra cost. If an adult wants to join in on the slime fun, they can purchase ticket or be included as a sliming guest.
Yes, they absolutely can! Admission tickets for siblings can be purchased in advance online, though they may not be able to make slime in the same area as the party due to space. Guardians with the party don’t need tickets if they’re not participating but can buy tickets if they’d like their own experience and participate with the siblings.
Yes! The Slime Lab is a museum open to the public during regular hours, even while parties are in session. Don’t worry — your dedicated party host (Slimeologist) will guide your group through exhibits and slime-making activities, keeping your party together at all times.
Arrive up to 10 minutes early to access your party room, but here’s the fun part—if you drop off or mail your decorations (like drinks, tablecloths, banners, and goodie bags) at least a day ahead, we’ll handle the setup for free! Alternatively, when you arrive the day of, we’ll take care of any decor setup (banner placement, table cloths, themed paper goods, goodie bags, etc) while you dive into the Slime Lab fun with the birthday star for a totally stress-free party experience. Let us do the heavy lifting! We just kindly ask that birthday banners, goodie bags and centerpieces be already assembled for easy placement.

We leave it to the party host and the toddler’s parents to determine if their child would like to participate and count as a sliming guest and make slime. Free sensory play is provided for children 1 and under.
We recommend slime creations for ages 3 and up. Younger guests often enjoy slime sensory play, especially if they’ve used slime or playdough before. For groups with children 5 and under, we suggest our least sticky textures for the best experience.
