What Parents Say

★★★★★Randomly came across Sophie’s slime factory and I can hands down say that Sophie and her enthusiasm will brighten you and your children’s day, party or no party! Very well organised and so many things to choose from. My daughter had so so so much fun! I’ve also decided to book my daughter’s birthday party here! Well worth the money and experience. Will be coming here every week 😅

★★★★★We reached out to Sophie to see if she would run a fun team workshop as a break off activity for our team planning day today - Sophie custom designed a session for our team and we hosted a slime workshop on site. The team loved it And we got to take the slime home and our kids have been playing with it all afternoon. What a great local business ❤️❤️

★★I came across Sophie’s Slime after reading so many reviews, and I was genuinely excited to bring my kids along for what I hoped would be a fun and creative experience. Unfortunately, I left feeling quite disappointed. The drop in session felt extremely limited in terms of what the kids could actually do. The staff didn’t seem particularly engaged or enthusiastic, which made the overall atmosphere quite flat, it honestly just wasn’t fun. For a space built around something as fun as slime, it really lacked that spark. It would be great to see more structured or varied activities throughout the space to help keep kids be engaged and excited. Something as simple as themed slime stations or interactive challenges could go a long way. To be honest, the drop-in fee didn’t feel worth it. My kids had a lot more fun at Lollipop’s Playland. That said, judging by the photos and setup, the birthday parties might offer a better experience than the drop ins. But as far as casual visits go, there’s definitely room for improvement.

★★★★★We recently celebrated our eldest daughter's birthday at Sophie's Slime Factory, and it was such a wonderful experience. She, her little sister, and her friends had the best time making slime and getting messy in the most fun way! What made the day truly special was how kind, inclusive, and accepting the team was. Our daughter and her friends are all deaf, and the staff went above and beyond to make everyone feel welcome. They showed real interest in learning Auslan and even joined in signing the "Happy Birthday" song, a moment that really touched our hearts. Thank you to Sophie and the team for creating such a fun, safe, and inclusive space. It meant the world to us and our eldest daughter. Our youngest daughter already says she wants her birthday party here, too! Highly recommend for anyone looking for a unique and thoughtful party venue.

★★★★Loved this place for my Daughter’s 7th Birthday Party. The staff were friendly and helpful and it was an easy party to plan as it was all done for you! The addition of a cheese platter for the parents was a perfect idea too. Would definitely recommend this place. The kids had a ball and all want to go back.
