Washable Safe Non-Toxic
This activator solution links the long chains of slippery PVA glue molecules (polymers) to create amazing super-stretchy SLIME.
Scientific Sue’s Recipe:
- 80 ml PVA glue
- 20 ml water
- Handful of coloured Crazy Soap Foam
- 15 – 30 ml Super Slime Activator
Always shake your bottle for 15 seconds before you make your slime to activate the chemicals.

A little bit of Science History
Sodium tetraborate, is also known as Borax (Na2B4O7). It is a natural mineral mined from the ground. Borax can be found in laundry boosters, multipurpose cleaners, hand soaps, and in some kinds of toothpaste.
Borax was discovered over 4000 years ago. The name borax is derived from the Persian word borak, meaning white. It was used as a flux for soldering by the Egyptians, and this is still one of the more important uses for it today.
Borax was probably first imported to Europe by Marco Polo around 1300, and it was used in trade for many years afterward. It is usually found deep with the ground, although it has been mined near the surface in California since the 1860’s.
Borax crystals are odourless, whitish in colour and alkaline. It is sometimes used as an emulsifier, buffering agent, or preservative for moisturising products, creams, shampoos, gels, lotions, bath bombs, scrubs and salts.
However, for us it is the key ingredient, combined with glue and water to make SLIME, a gooey material that many children love playing with.
