Distilled water is what happens when you let water take a very long, very hot bath. You boil the water, catch the steam, and condense it back into liquid—leaving minerals, bacteria, and pretty much everything else behind.
Think of it as the lobster pot of purification: only the pure H₂O escapes as vapor. Fun fact: this is how nature makes rain, minus the kitchen stove. Distillation is the oldest trick in the book, used by ancient Greeks for medicine and alchemy.
It’s incredibly effective, but it’s also a slow, energy-hungry process. You’re basically running a kettle for hours. Plus, that pure H₂O can taste a little flat—like drinking a cloud that forgot its personality.
