## Description

Slime Labs All-In-One Slime Activator (300ml), Non-Toxic, UK Made : desertcart.co.uk: Toys & Games

Review: Brilliant slime activator – works really well! - I’ve tried a few different slime activators and this is definitely one of the best I’ve used. It’s really easy to use and works quickly, turning the mixture into a proper stretchy slime without having to add loads. I particularly like the large 1-litre bottle as it lasts ages and is great value, especially if you make slime regularly. We’ve used it with PVA glue and different slime recipes and have had really good results. Just add a little at a time and keep mixing until you get the consistency you want. Really pleased with it and I’d definitely buy it again. Highly recommend for anyone who enjoys making their own slime!
Review: Good value - Great value as you only need a dribble to activate a lot of glue into slime. Safe ,clean , works what else to say.

Great value as you only need a dribble to activate a lot of glue into slime. Safe ,clean , works what else to say.

### ⭐⭐⭐⭐ Works, after a fashion
*by R***Z on 11 May 2026*

Works pretty well. 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.
