Chemistry class chaos in one perfect meme! The teacher's face says it all while supervising a lab full of disasters. One student casually licking hydrochloric acid (seriously dangerous), another snorting mystery powder (terrible idea), someone mixing sodium and water (explosive reaction), and the poor kid who didn't wear gloves with salt water (which seems innocent until you realize salt water conducts electricity and can cause chemical burns with certain compounds). Meanwhile, the teacher is experiencing all five stages of grief simultaneously. This is why chemistry teachers have that thousand-yard stare by retirement.
