Laboratory safety Memes

That guilty feeling when you've just committed a chemical crime! Every chemist knows the environmental sin of dumping organic solvents like hexane, toluene, or dichloromethane down the sink. Those compounds are environmental nightmares - they contaminate water supplies, kill aquatic organisms, and some are even carcinogenic. The proper disposal involves collection in waste containers for professional treatment. But sometimes when no one's looking... that methanol rinse might accidentally find its way down the drain. The divine disappointment is palpable!

The forbidden taste test of the periodic table! Green means "lick away" (hello carbon and oxygen), yellow is "proceed with caution" (phosphorus might make your tongue tingle), red screams "NOPE" (sodium would literally explode in your mouth), and purple says "are you actually considering tasting radioactive elements?!" The cartoon guy at the bottom is basically every chemistry teacher who saved students from their own curiosity. Fun fact: mercury used to be used in medicine before people realized it's, you know, SUPER TOXIC. The original mad scientists definitely licked things they shouldn't have—that's why we have safety protocols now! Your tongue thanks science for learning these lessons the hard way.
