Demonstration of Thermodynamics and Kinetics Using FriXion Erasable Pens
Campbell, Dean J.; Bosma, Wayne B.; Bannon, Stephen J.; Gunter, Molly M.; Hammar, Margaret K.
Journal of Chemical Education, v89 n4 p526-528 Mar 2012
FriXion erasable pens contain thermochromic inks that have colored low-temperature forms and colorless high-temperature forms. Liquid nitrogen can be used to kinetically trap the high-temperature forms of the ink at temperatures at which ordinarily the low-temperature forms are more thermodynamically stable.
