1. Pour water in a bottle
   
2. then pour oil in the beaker
3. then put 5 drops of any food coloring
4. then shake the bottle with the cap on

Science:

Water and oil doesn't mix because water molecules are polar – they have a small positive charge at one end and a small negative charge at the other end, and they stick to each other. Oil molecules are non-polar – they have no charge. Because of this, oil molecules are more attracted to each other than to water molecules, and water molecules are more attracted to each other than to oil molecules.
