  • This colour increases in intensity when exposed to direct sunlight
  • The colour change is reversible, although it takes about 60 seconds for the liquid to become clear again
  • Makes a fantastic demonstration of photochromic phenomena
  • The same dye chemistry is used in photochromic lenses, special window glass etc
  • Photochromic cells, for quantitative measurements, can be made, by trapping a drop of the fluid between microscope slides or petri dishes
