Slime Party at Castle Hill: Six hands-on slimes, a hosted celebration, and a playland of gooey mischief
A hosted, sit-down slime-making party for children that finishes with party food and free play in an on-site slime playland.
Slime Party at Castle Hill: Six hands-on slimes, a hosted celebration, and a playland of gooey mischief.
At Sophie's Slime Factory in Castle Hill, a bright, hands-on studio session turns ordinary partygoers into makers: over roughly 1.5 hours children are guided through the process of making six different textured slimes—fluffy, glitter, crunchy and more—before settling in for party food and extended play in an adjoining slime playland.
Highlights
Outing Highlights
Make six distinct slimes from scratch
The party curriculum walks kids through slime-making from plain glue to finished, coloured and textured slimes—six varieties in total—so each child leaves with multiple take-home creations.
Hosted party food and cake time
After the slime session the group shares party food and cake in a hosted celebration setting, keeping the focus on a contained, mess-forward party experience.
Slime throwing, sensory play, and a communal slime wall
When the hosted portion ends, guests can stay to explore the playland—slime throwing, sensory tables, and a slime wall are among the activities on offer—plus discounted extra slimes if kids want to make more.
What the day feels like
What the party feels like
The rhythm is deliberate: check in at the studio, gather at communal tables, follow step-by-step instruction to mix and colour six slimes, then move into a relaxed party meal and supervised free play in the adjacent slime playland—an engineered, deliberately messy celebration designed to keep slime in the venue, not your home.

Frequently asked questions
Planning Your Outing
What age do you recommend for slime parties?
We recommend slime parties for children aged 4 years and up; if a few guests are under four, a parent must accompany them for the duration of the party.
What are the available time slots?
There are two 10:30 a.m. slots and two 1:30 p.m. slots available each day to ensure hosted time is followed by extra play before the next party.
Is there a minimum or maximum number of guests?
Yes—parties have a minimum of 12 guests and a maximum of 50; contact the operator if you wish to discuss larger options.
Do I need to book in advance?
For party packages you should arrange the booking; for casual drop-ins to make slime there is no need to book—slime making is available for $20 per slime during opening hours.
Can I bring external food or drinks?
If you've booked a slime party you are welcome to bring extra food or drinks for parents and kids; drop-in visitors may also bring food or drinks but are asked to clean up before leaving.
Can parents stay for the slime making?
Yes—parents may either drop children off or stay to watch; each party room includes a designated seating area for parents who choose to remain.
How should I care for slime after the party?
Store slime in the provided container with the lid on; small fixes include adding contact lens solution (with borax) or a pinch of baking soda for stickiness, lotion for hardness, or warm water for stiff clear slime. Do not eat any slime or contents.
