This image, taken by Grover Schrayer, depicts a rainbow casted over smoke from a blown out candle. Burning a candle results in Carbon Dioxide and Water Vapor. After the candle is blown out, the wick remains warm while the surrounding areas begin to cool down rapidly. Some of the candle wax continues to melt while other parts vaporize into water droplets. When the picture was taken the light from the camera refracted off the tiny vapor droplets in the smoke and on the wick creating iridescence shown as a rainbow. This unique flow of the smoke originally caught my attention. The art in this image fascinates me not only because of the beautiful aesthetic but also the beauty of both chemistry and physics.
