Thermochromism. A hand print on thermochromic paper. The paper has a liquid crystal compound encapsulated to its surface. The spacing between layers of the crystal is sensitive to heat - as heat is applied the distance between layers decreases. At room temperature,the distance is such that the crystal absorbs light (appearing black). As it heats,the distance decreases and the crystal reflects a specific colour depending on the heat from reddish-brown (coolest) to blue (warmest). The crystal will eventually return to room temperature and the hand print will disappear | |
