Gather materials and cut coffee filters into strips.
Dissolve candies in a small amount of water.
Use a pencil to draw a line on the coffee filter strip.
Place a drop of the candy solution on the line.
Suspend the strip in a glass container with a small amount of water.
Allow the water to rise up the filter and separate the dyes.
Record the colors that separate as the water rises.
Compare results from different candies.
It is expected that the different candies will show unique patterns of dye separation, demonstrating how chromatography works.
