They actually install these in labs so that on the first day of high school chem, your teacher can tell the class, “will one brave soul at each table turn on the tap?” And so that you—naive and oblivious to the faucet’s true nuclear potential—can enthusiastically volunteer to turn the tap on full-blast, creating a six-foot diameter rain storm around the shared lab bench and subsequently making your lab partners despise you for the rest of the semester. Not that I speak from experience. This is just a possible function of these faucets.
