In this experiment, we will look at dry-erase markers. These markers contain non-water soluble materials (or hydrophobic). They are made up of a solvent, which is usually some kind of alcohol. This is used to dissolve the color pigments that determine the marker’s color.

In addition, a resin or polymer is added, which is the key to making the ink erasable. Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded.
