After placing the dyes on the pencil line the water starts gradually rising up by capillary.
- As the water moves up it take the dyes present ink the ink along with it
- as the water rises up we see different colours on paper , these are the different dyes in the ink
- different dyes have different soulbility levels and travel at different speeds as the water travels up
- as a result we see different coloured strips at different heights and the dyes are separated
- different dyes have different soulbility levels and travel at different speeds as the water travels up
- as the water rises up we see different colours on paper , these are the different dyes in the ink
