Center Stage Use a clean, dry coffee filter circle. Use your marker to draw a black spot in the center. Put the circle on a saucer, and put a few drops of water on the spot. In a few minutes you'll see rings of color that go out from the center of the circle to the edges. Our picture is in black and white, but when you do this, you'll see some amazing colors.
Most nonpermanent markers use inks that are made of colored pigments and water.
On a coffee filter, the water in the ink carries the pigment onto the paper. When the ink dries, the pigment remains on the paper. When you dip the paper in water, the dried pigments dissolve. As the water travels up the paper, it carries the pigments along with it. How fast each pigment travels depends on the size of the pigment molecule and on how strongly the pigment is attracted to the paper.
