Try this at home - magical ink

Hello JRCS Scientists,

Let's start 2016 with an experiment which will allow you to test diffusion (click here to read more about this process).

You will need:
  • 2 glasses or jars
  • hot and cold water
  • blue ink
  • vinegar

Method:
  1. Fill one glass with cold water and the other with hot water.
  2. Next, add 3 drops of ink into each glass and gently stir it.
  3. You will observe that the cold water turned blue and the hot water stayed clear.
  4. To make the hot water blue, add a teaspoon of vinegar and stir it.
