Safety evolution Memes

From mouth-pipetting concentrated sulfuric acid to panicking over a drop of dilute acetic acid on a glove - chemistry safety standards have come a LONG way! 😂 The 1950s chemist is literally using their mouth to suck up H 2 SO 4 (one of the strongest acids that can literally dissolve your face), while today's chemist is having a full-blown crisis over 0.001M acetic acid (basically slightly stronger vinegar) touching their protective gear. Fun fact: Mouth pipetting was actually a common lab practice until the 1970s! Scientists would literally taste unknown chemicals to identify them. And you thought YOUR job was stressful!
