This particularly wet undergraduate was wandering aimlessly round the lab peering into fume-cupboards and scouring shelves of flasks and bottles, obviously looking for some vital reagent for their experiment.
Dr Helpfull Graduatestudentisch approached the rookie and asked what he was after. ‘Copious water’, was the reply, ‘it says use copious water to cool the reaction…so I was looking for the flask’.
Hearing of this, the resourceful lab technician printed off some labels for the distilled water bottles – ‘COPIOUS WATER: Use sparingly’. Take heed, they’ll be bottling it at source pumping in CO2 under pressure and charging for that hydrated dihydrogen monoxide next you know!
