For my mixed rotation project, I took a visit to Whitaker Lab and photographed engineering students working on their respective projects.  Pictured above is a student grinding a metal bar.  The result of high speed friction between the rotating blade and the metal bar results in visible light sparks.  Lately, I have been interested in photographing settings that show light in a unique way, especially in dark backgrounds that accentuate the visibility of the light.  It is fascinating to watch a shower of sparks bouncing off a table!  I also took some other photos in the lab that I thought were pretty interesting.
