Oil water purification can easily be done with the help of our hairs. You just need to do these steps-

- collect hairs in a cruet (kuppi). 

-place the cruet(kuppi) in a bottle for collecting residual water.

-Pour the oil water inside the cruet(kuppi) full of hairs. And you will see the residual water is oil free. And for more purification use filter paper in the cruet(kuppi). 

This water can be use in anywork like washing clothes, dishes and many more. 

This experiment can be used in a science exbition. 

-slowly pour oil water inside the cruet(kuppi).
