Forbidden techniques Memes

The forbidden technique that haunts lab safety officers everywhere! Before mechanical pipettes became standard, scientists would literally suck up liquids using their mouth and a glass tube. Modern lab protocols strictly forbid this practice because, you know, accidentally inhaling concentrated hydrochloric acid tends to ruin your whole decade. Yet every chemist has that one dangerous reagent they secretly wish they could taste-test like a fine wine. Safety protocols exist for a reason, but the temptation to break them is the scientific equivalent of touching wet paint despite the sign.
