Markers can be permanent, easily rubbed off, and even have lots of scents! Markers bring color to our world. But, all of the action is actually happening inside of the marker. Inside that plastic tube is an absorbent material. This holds the ink that gives each marker its color. The ink itself is made of a pigment or dye to give it a color, a resin to make it stick to a writing surface, and a solvent to make the ink move through the marker. As the marker moves across the paper, the ink from the absorbent material is sticking to the paper. That is how markers work!
