Included with Slimetastic Creation Party!



Starting April 11th, 2024, thanks to the expansion of our slime lab, we’re excited to accommodate larger parties and welcome walk-ins, making your slime-filled celebrations bigger and better than ever!

You may arrive as early as 30 minutes, but do keep in mind that if decorations (including drink and goodie bags) are dropped off (or mailed in) at least one day before, we can take care of set up for you at no additional costs.

Unfortunately at this time there is no refrigeration available for these items, sorry.

Family parties are welcomed to BYOB for their guests 21 and over, we can provide a sectioned area for drinks.

Yes, we set up tables for food/drinks/cake as well as one for gifts and goodie bags.

We will provide a credit that you may use at a later date without expirations towards slime or virtual reality.

Yes, every participating including the guest of honor counts.

We leave it to the party host and the toddler’s parents to determine if their child would like to participate. For children 2 and under who wish to participate in SENSORY play only (no slime lab creation) there is a $15 admission fee.

We recommend slime lab creations for ages 3 and up, although many of our younger guests participate in slime sensory play and often build a slime according to our recommendations (least sticky, most manageable, no charms due to choking hazard).

Once you make a reservation, you will receive a follow up e-mail with important information including how to obtain digital invites (free of charge) as well as how to start your dedicated text chat where you can communicate with us and ask questions leading up to your event. Digital invites are usually provided within 72 hours of your request (excludes weekends and holidays).

We kindly ask that you check in with us one week prior to your party so that we may adjust the number of guests to those that RSVP’d.

You can reserve a Slime Lab party with just $174.50 online, by phone or by text. The remainder of the balance, including additional sliming guests will be paid the day of your party.

Our Slime Lab parties start off with 15-20 minutes of Slime Sensory play with a variety of slime textures and tools, followed by our giant slime bubble challenge. Guests then proceed to making their own custom slimes by adding color, scent, choosing from 100+ toppings, and adding charms. The birthday individual is then photographed at our slime photo booth and then trapped inside a giant slime bubble. Guests then proceed to eating/drinking.

Dedicated text chats allow you to communicate with us freely to answer questions leading up to your event. You may initiate your text chat by texting us to 203.632.9651.

Our expert instructors will guide your party guests through the enchanting process of creating their own custom slime creations. From choosing the perfect colors and delightful textures to choosing from 100+ toppings, charms and scents.  Every child has the opportunity to design a unique slime masterpiece. The joy of crafting something with their own hands will leave them beaming with pride.
