I used to have a little G.I. Joe guy called Zartan,
Sing it with me now:
He’s an evil master of disguise
Changes color right before your eyes
Anyway, as the song sez the thing did in fact change color in ultraviolet (sun)light. In laymans terms, how do these new plastics that change color in sunlight and with heat work?. And please refrain from words like “electron” “orbit” and “polymer” in favor of “magic color pixies” whenever possible.
