Here’s a wild fact: Pure water doesn’t conduct electricity well. It’s the minerals in regular water that make it a conductor. So distilled water is basically electricity’s worst friend—great for safety, boring for science experiments.
Also, distilled water can be slightly acidic (pH around 5.8) because it absorbs carbon dioxide from the air. Purified water usually sits closer to neutral pH 7. Your stomach doesn’t care, but your taste buds might side with the purer option.
Pop culture nerd alert: In the movie The Martian, Matt Damon’s character produces water by burning rocket fuel. That’s technically distillation. So if you ever get stranded on Mars, you’ll know what to do—but for now, save yourself the hassle and buy a filter.
