Imagine you’re a bouncer at the world’s snootiest nightclub. The club is your drinking glass, and the bouncer is a semi-permeable membrane. This membrane has holes so tiny that only water molecules can squeeze through, while everything else—lead, chlorine, pesticides, that weird pink slime—gets firmly told, “Sorry, you’re on the list. The no list.”
The process is called reverse osmosis because it uses pressure to push water against its natural flow. Think of it as forcing a shy kid to dance at a party—except the party is your liver, and it’s grateful.
