I have a real fear of chemical mixing. The chance of something drastic happening like a fire or worse an explosion frightens me to death. I was once in my lab in high school when one of my fellow students lost his eyesight becuse he carelessly mixed two re-agents that we were specifically told by our teacher to stay away from. I walked into the grand hall of the music center the other day and there was a crew there mixing paints for the refurbishing of the hall. I had to turn around and leave because of my nervous anticipation of what could go wrong. As phobias go, I guess I could have a worse one.
