You engineers are all the loving same you just whine about how long stuff takes to do right and why the teachers or teacher assistants won't do it for you or why machines aren't doing it and go ahead, cry me a loving river. You are going to sit at the loving bench and put together your loving burette for titrations or table or whatever the forget it is you're supposed to do and once it's done I am going to put it through a UV-VIS spectrometer or put half a tonne on top of it and if it doesn't peak at 320 nm or breaks I'm lighting you and the burette and the table on fire with triethylborane.
