Understanding Food Dye

Caption

Scouts Sloane (left) and Katie (far right) listen to student volunteer Jasmin Wright explain the M&M chromatography experiment. Students separate the food dye mixtures used to color the candy coatings. The dyes' properties determine how fast they creep up the filter paper when immersed in salt water, resulting in separation.
