Input: Text: this was several years ago in high school chemistry class. you know how filling a pipette to the exact amount can be annoying, because when you have about the right amount, the moment you release the squeezy thing the level changes again. well the teacher was saying that mouth pipetting is more accurate. he didn't demonstrate, so he probably thought it was obvious how to do it. i tried it. not only was it difficult to control steadily, i couldn't really see the target line. i ended up with a mouthful of brown acidic solution (i don't remember what it was but i suspect iron sulfate or iron hydroxide). the teacher didn't notice and i was too scared to ask what to do. i washed my mouth thoroughly after class but it felt ten times worse than the feeling on your teeth after drinking fizzy drinks.
