Making Gloop with First class!!


We used cornflour, water and food colouring to make gloop. The ooze is made up of tiny, solid particles of corn flour suspended in water. This type of mixture is called a colloid. It behaves strangely!! If you stir a cup of tea with a spoon, the tea moves out of the way easily, no matter whether you stir it quickly or slowly. But the colloid will resist the movement if you stir it quickly.
