Danger alert

Today's new phd comic is very fitting. John has been let loose in our lab. We did clear his desk for him first, to reduce the danger potential [think radioactive plants (though under a lead-lined perspex box), syringe needles and razor blades]. We have a summer student and a visiting PhD student, and John likes to use the opportunity to put a lab coat on and show them what to do. We would feel a lot safer if John wouldn't keep explaining how to make liquid nitrogen and dry ice bombs, and wave his hands around whilst holding bottles of toxic chemicals.

We've printed the comic strip out and stuck it to his door. I think he may get the hint.
