Rainwater is technically distilled by nature—evaporation leaves the minerals behind. So, fresh rainwater has almost zero electrolytes. It’s like water that just graduated with a degree in purity.
But wait! Once rainwater hits the ground, it immediately starts picking up minerals from soil and rocks. So, the puddle you just splashed through? It’s now an electrolyte cocktail.
Unless you’re a frog, you probably shouldn’t drink it. But it’s a fun fact to drop at parties: “Did you know rainwater is the original distilled water?” Watch everyone pretend to be amazed.
