Place 1/2 cup of water in an old or disposable medium bowl. Pour in the entire bottle of glue and mix together.
Add as much food colouring as you desire until your favourite colour is achieved.
In a separate container, heat one cup of water. Wearing gloves, carefully add 1 tbs of Borax and mix well until it dissolves. Add the remaining 1/2 tbs of Borax and mix well.
Wearing gloves pour the Borax water into your glue mixture and stir well. It will immediately start to clump together and form a glob in the centre with liquid surrounding it.
Carefully lift out the glob and squish it in your gloved hands until it becomes less wet and binds together. Discard the excess liquid that remains in the bowl.
