Introduction

Kids have this sudden inclination towards colours, don’t they? They can play all day long with these colours and not feel unhappy about it at all. Also, there are tons of science experiments that can be carried out using these colours. One such excellent discovery comes right here with the help of dyes and colourful markers.

Colours are nothing but a mix up of different coloured dyes. The experiment that is going to up will explain everything and the science behind what happened and how! So, continue reading the science as well as to find out how the experiment is conducted.

Apparatus

  1. Paper towels that are properly cut into equal size strips.
  2. A big bowl full of water.
  3. Markers – 3 or more than three which must include the black colour.

Procedure

Step 1

Take the paper towel strips and put them where you want to conduct the experiment. Take a pencil to draw a line of any structure from the bottom of the paper towel to half an inch.

Step 2

Make sure to mark the lines with the marker pencils and use different colours every time.

Step 3

Now, time to use the big bowl of water. Take these paper strips and dip it into the water keeping the bottom edge of this towel completely submerged. Also, ensure that the line of the ink is kept as it is and is not submerged in the water.

Step 4

Hold the paper towel exactly where you want to hold it and observe the water creeping through the towel.

Step 5

You can see the ink marks spreading all along the paper towel. Along with that, you can also see the different dyes along with the original colour they are holding.

Result

Are you a little curious and want to know how everything happened? Well, no worry as we have a perfect explanation for you!

After you dip the paper towel in the colours and it draws the liquid from the bowl. Now, the molecules of the water make a connection which we call bond with the molecules of the different coloured inks. This is the reason why the colour starts to spread all over the towel.


Now, you can also separate these colours from the paper towel with the help of a process which is called “chromatography”. The process of dividing different components of a mixture from another is called chromatography.

While you are going through the process, you can see the different shades of purple leaving the blue colour and the red colour. The green colour breaks into yellow and blue. This is how chromatography works.

Conclusion

So, now that you know how to extract the colours from the dyes, make sure to indulge yourself more and find out the hidden mystery behind these colours.
