"SNOWFALL" -Photograph of crystalline acetaminophen found in Tylenol®"Snowfall" is a fantasy winter forest scene of the imagination. This photograph of acetaminophen crystals was created by growing the crystals by evaporation of a solution on a glass slide, then photographed through the microscope. The crystals are formed resulting in a unique pattern each time. The subtle colors occur naturally by refraction of light as it passes through the crystal facets.
