As the water travels through and down the paper, it picks up ink particles and carries them along with it. This same process can be put to good use as a technique called paper chromatography.
Chromatography includes a group of techniques that separate the various components in a complex solution. In each chromatography setup there is generally a so-called mobile element a fluid in which the components are dissolved and a stationary aspect the material the fluid moves through. For example, in paper chromatography water is the mobile phase and paper is the stationary phase.
The solution's components ideally move at different speeds as they travel through the stationary phase so that they can be separated.
In paper chromatography different pigments can be separated based on their solubility, or their ability to dissolve in water. The more soluble a pigment is, the more readily it will dissolve in the mobile phase and the farther it will usually travel as it is carried by the water being absorbed into the paper.
Thicker ones will work better. Make each strip at least one inch longer than the height of your large jar. To get approximately one eighth teaspoon you can fill a one quarter teaspoon measuring spoon so that it is half full. Pour a small amount of the salt solution into a large jar with a narrow opening so that the jar is about one inch full. Leave it there for another three minutes. Then remove the candy. Do you see the dye soak into the strip, coloring the area around the line?
You can get some extra dye on the line by dabbing the sides of the wet candy with it. Put a small drop of food coloring on the plate and lightly dab the line on a new strip against it. Repeat this so that you have three food coloring strips one each for the red, green and blue food coloring.
Put the strip into the jar until the strip just touches the saltwater. Drape the top of the strip over the jar's opening and secure it with a clothespin. My daughter did notice that some candies were actually made up of a couple different colors mixed together and that really was the point of this super simple introduction to chromatograph. The green dye is actually made up of blue and yellow but the blue masks the yellow and simply shows up as green on the filter paper.
I explained the the different colors used to make brown flowed up the paper at different rates and that is why you can see the different colors.
The different rates of attraction and how well a substance dissolves in water determined how much separation you will see with your dyes. For even more scientific fun, grab 30 easy-to-follow science experiments kids will beg to repeat plus a no prep science journal to keep track of their results!
