You Light Up My Life (One: Chemical and Biological Cold Light)
Scientific Discipline — Chemistry
Mother Nature thought it up millions of years ago, and what a neat idea! Learn about and see animals that have their own set of headlights and can turn them on and off at will. See how scientists are able to recreate this cold lighting in the laboratory. Find out how glow-in-the-dark bracelets work and see how any color light can be produced by the addition of various chemicals. Discover the phenomenon of fluorescence and phosphorescence and learn how these and other forms of luminescence are relevant in our daily lives.
