There was an almost catestophic incident in the lab today involving a regulator with reversed threading (anti-clockwise rather than clockwise) and a large cylinder of compressed hydrogen. I've never seen scientists move so fast (running away, followed by running back to make sure the guy in question was okay).
Fortunately, there were no open flames nearby. But I almost lost a supervisor.
I have also a list of changes I need to make to my confirmation report. I don't want to make the changes, however, I want to get heaftily drunk.
