Description

This Super Slime Activator Kit is part of Science2Life’s ‘Science It!’ Programmes

Washable Safe Non-Toxic

This activator solution links the long chains of slippery PVA glue molecules (polymers) to create amazing super-stretchy SLIME.

Contents:

• 1 x 1 L Bottle (reusable) containing slime activating crystals
• 1 x spare sachet of activating crystals – which makes a further 1 litre of slime activator!
• 1 x 30 ml measuring cup
• 2 x 3 ml pipette

Using Crazy Soap Foams to colour my Slime

Scientific Sue’s Recipe:

• 80 ml school PVA glue
• 20 ml Water
• Small squirt of paint/food colour
• 30 – 40 ml Super Slime Activator

Always shake your bottle of activator for 15 seconds before you make your slime to activate the chemicals.

The bottle is reusable! Want more activator – just buy the sachets of premixed powders from us.

Note:

1. Not all PVA glues are the same. Some will already have been watered down – hence the amount of water required to make the slime consistency of your choice varies from glue to glue
2. The amount of activator required depends on the PVA glue you are using – Use measuring jugs and /or measuring cups to carefully note the amounts used. Remember to write down these values!

I bought a clear PVA glue called cleopatra – to make an awesome slime with it I only need 30 ml of the glue added to 70 ml of water!

Try adding: Baby oil, bath or shaving foam, hand lotions or glitter to change the texture of your slime.

Comes with FREE 30 ml measuring cup and 2 small pipettes to help with your children’s scientific explorations!

Safety: Contains Sodium Tetraborate (Borax). Adult supervision required. Not suitable for children under 5. Wash hands before and after use.

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.
