Product Information

Introduce the topic of energy conversions and photochemical reactions with this bright and fun demonstration. Students observe how light will activate a chemical reaction. Simply place the thionin solution on an overhead projector and watch the deep purple color quickly change to colorless. Remove the light and the solution will slowly return to its original purple color. You can also cover half the bag and watch only half of the bag change color.
