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.

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.
