Children wearing safety goggles mix bright green slime during a hands-on kitchen science experiment—learning through messy, magical STEM play!

Welcome to the squishy, stretchy, super-fun world of slime making — with a scientific twist!
Whether you’re a budding scientist, a creative crafter or an enthusiastic educator, Scientific Sue’s Super Slime Activator Kit gives you everything you need to make perfect slime at home, in the garden — or with your classroom of curious kids.

Inside your kit you’ll find:

• 600 ml of premium PVA glue — the fluffy, sticky base for satisfying slime texture.

• 500 ml of slime activator liquid — specially formulated to transform glue into stretchy, squishy slime.

• 10 measuring cups (each 30 ml) — to help you pour just the right amount of glue or activator.

• 5 small pipettes (each 5 ml) — for precise measuring, slow drips or creative slime-lab experiments.

With these tools, you can explore slime-making as a fun hands-on activity or a playful science lesson. Mix the glue with water and activator, stir and knead — and soon you’ll have ooey, gooey, squishy slime that’s perfect for sensory play, classroom science or family fun.

Get ready to stretch it, poke it, squish it — and above all, experiment! Because with every slime batch, you’re not just making slime… you’re bringing Science2Life.

The Ultimate Slime Science Guide

• Always wash hands before and after use
• Keep away from eyes and mouth

Scientific Sue’s Favourite Slime Recipe

Bath foams aren’t just for bubbles — they’re perfect for adding colour and changing the texture of your slime! Safety goggles on, slime at the ready!

Perfect for beginners and slime pros alike!

• 15 ml PVA glue*
• 45 ml water
• A small squeeze of paint or food colouring
• 10–15 ml Super Slime Activator

(*Tested with Brian Clegg, Cleopatra, Classmate Blue Label, and Sticky Situations clear PVA glues.)

Note: Some glues are pre-diluted, so experiment a little to get the texture just right!

How to Achieve the Best Stretchy Slime

How to Achieve the Best Stretchy Slime

The exact amount can vary slightly depending on the specific concentration of your PVA glue, so it is best to add the activator solution a little at a time and stretch and fold the mixture to reach the desired consistency.

1 Start with your basic mixture

• 15 ml glue + 45 ml water

2 Add activator slowly

• Add 1–2 ml activator, stir 20–30 seconds.
• Add another 1–2 ml and mix again.
  Slime will thicken around 20 – 30 seconds as cross-linking begins – patience pays off!
• It takes time for the links to be made, if you add more activator before the links have been made your slime will be stiff and will break easily.

3 When slime pulls away from the bowl

Begin handling and stretching + folding.
This improves elasticity by aligning polymer chains.

4 If still sticky

Add only a few drops at a time.
Too much activator = stiff, rubbery slime.

5 Sue’s favourite consistency

15 ml glue: 45 ml water
What will yours be?

By following these steps and adjusting gradually, you can achieve the perfect stretchy slime consistency.

Sue’s Top Slime-Making Tips

• Shake well! Give your activator bottle a good 10-second shake before use.
• Different glues = different amounts of water and activator
• Measure carefully using the included cups and pipette.
• Keep a slime diary! Record your favourite recipes so you can recreate that perfect slime again and again.

The Science Behind the Slime – Meet Borax!

Sodium tetraborate —also known as 

• Used by the ancient Egyptians for metalworking and mummification
• Brought to Europe via the Silk Road around the 1300s
• Mined near the surface in California since the 1880s
• Today it’s found in laundry boosters, cleaners, hand soaps, gels, lotions, bath bombs… and of course SLIME!

When the activator is mixed with PVA glue, it causes cross-linking, turning runny glue into a stretchy, bouncy polymer –  SLIME!

Despite common myths, borax is safe when used properly, and it’s a brilliant way to explore real chemistry through hands-on play.
