Gooey Slime

Instructions

1. Dissolve borax into the water. Keep adding borax wont dissolve anymore (its totally saturated).

2. Gently add 100mL of the super-saturated borax solution to the PVA glue and stir.

3. Add another 100mL of borax solution and stir again. Seeing anything yet?

4. Keep adding borax solution to the PVA glue until a thick slime has been produced.

You will need:

- 50mL PVA Glue in a cup

- Borax: found in the homecare aisle of the supermarket

- Food Colouring

- Mixing bowl and spoon

Polymerization is a very important chemical process that is used to produce all sorts of plastic products for everyday use... e.g.: nylon, paint, synthetic rubber and even chewing gum! The process really involves the joining of small molecules to form long chains that keep repeating.

PVA glue contains polyvinyl acetate (also known as PVA), a chemical which is made up of carbon, hydrogen and oxygen atoms. PVA reacts with the 'sodium tetraborate' in the borax solution, forming giant chains of cross-linked carbon atoms.
