Cyanoacrylate Fuming
Cyanoacrylate Fuming was discovered accidentally by a Japanese scientist who knew his friend would appreciate his mess up/discovery.  See if you can find the names of these two scientists!  Scientist one was working on his computer when he spilt some on his keyboard.  Under the hot conditions, the put off fumes that attached to the oils from the scientist's hands.  The scientist could see his prints on his keyboard.  He went next door to his friend, who worked with prints, and told him what happened.  Now, is used to fume any potential prints that would normally be hard or impossible to get.  The biggest example is the human body.  The rough surface was a roadblock for dusting but the cyanoacrylate attaches to the surface oils, pulling out the prints.  Two things are critical to know with fumes:  first, they are very toxic.  Second, the fumes are best activated in heat.  Both of these reasons are the basis for the tarps or tanks used to do the fuming in.  The fumes should be drawn off in a specialized hood to prevent contamination of breathable air.  By the way, if you haven't deduce it yet, cyanoacrylate is the main in !
