Nearly a decade later we're proud to be the UK's largest independently owned slime activator brand, still family run and still making every bottle ourselves right here in Britain. What makes us different is that we don't just sell activator - we manufacture our own. We've spent years perfecting our formula through real testing with real families, tweaking and refining until we got it just right. The result is a ready-to-use solution that's fast acting, consistent and works brilliantly every single time. Add your activator slowly to your PVA glue, a little at a time, and knead well between each addition. Give it a minute to work - you'll be pulling perfect stretchy slime before you know it. Too sticky? Add a few more drops. Too stiff? Add a small squeeze of fresh glue. Once you get the hang of it, perfect slime becomes second nature. From fluffy and cloud slime to butter, glitter, crunchy and scented - this activator works across every slime type. Add your extras to the glue before activating and the possibilities are endless. For the very best results, pair with Slime Labs Slime Glue - specially selected to work in perfect ratio with this activator so you get brilliant slime from your very first batch. Non-toxic, washable and safe for all ages. Trusted by families, teachers, therapists and slime lovers across the UK since 2017. Directions 1. Add slowly to your glue and mix until you reach the perfect texture. 2. Works with clear, glitter, or coloured glues for endless slime creations. Safety Warning For external use only. Avoid contact with eyes. Review: Good activator - It was a very good activator. It is a big amount so it can last long enough to make a good few slimes. I found with other activators that they either didn’t work or it took the whole bottle to make a slime but with this one a little goes a long way. Overall I thought it was great value as you get a lot and good quality I would recommend this activator. Unlike some others this one isn’t sticky and is more liquid and water like.

I found with other activators that they either didn’t work or it took the whole bottle to make a slime but with this one a little goes a long way.

Used this with some translucent pva glue from the kids stationary shop on the high street and it took a few small measures to get working. We had added a bit of acrylic kids paint and along with it being see through glue that might be why it took a while to work. Needed a lot of stirring. I’m sure contact lens cleaning solution worked better 5 years back when we last made slime. Knocking off a point for the need to re-add and lots of stirring. ## Frequently Bought Together - Ultimate 550ml Slime Activator For Making all Slimes, (Works Every Time) - Makes 60 BATCHES or 6 Litres of Slime - Add Only This to PVA Glue for Slime - 550ml with 6X Lolly Sticks - Amazon Basics All Purpose Washable School Clear Liquid Glue – Great for Making Slime, 3.8 litre Bottle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/57448521-all-in-one-slime-activator-550ml-non-toxic-uk-made](https://www.desertcart.us/products/57448521-all-in-one-slime-activator-550ml-non-toxic-uk-made) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-08*
