Whiteboard markers are designed to be removed from smooth surfaces. A glazed plate is very smooth, and therefore the marker man loosens from the surface. The pigments would have been absorbed and stuck if we tried this on clothes, paper, or another porous material. Whiteboard markers usually contain a silicone polymer, an “oily” and hydrophobic molecule. Hydrophobic means “water-fearing,” which means that the marker pigments can’t mix with water. The marker pigments are also lighter than water. Therefore, the marker man floats on top of the water.
