Its highly concentrated formula activates all slime types quickly and efficiently, making it ideal for creative play, sensory activities, and educational use. Trusted by thousands, it offers premium quality and value for slime enthusiasts of all ages. ## Description Product description We started Slime Labs in 2017 - a dad on a mission to make slime-making simple, affordable and fun. 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. Independently tested in a UKAS accredited laboratory for compliance with the European Standard on Safety of Toys and bears CE marking.
