Purified water

Okay kiddo, so you know how water is pretty much everywhere, right? But sometimes we need to make sure it's super duper clean because we're going to drink it or use it for special things like making medicine or electronics. That's where purified water comes in.

See, regular water has little things in it like dirt, minerals, or tiny living things called bacteria. That's totally okay for most things, but sometimes we want to make sure there's absolutely nothing in the water that could cause problems or make it taste funny.

So what we do is we take the regular water and we put it through a bunch of filters and special machines that remove all those little things. We might also use chemicals or other fancy methods to make sure the water is as clean as can be.

Once we're done with all that, we have purified water! It's kind of like regular water, but it's been cleaned up so much that it's basically just water molecules with nothing else in them.

So if you ever need to drink or use water for something really important, like taking medicine or making electronics, you might need purified water to make sure everything goes smoothly. But for most everyday things, regular tap water is just fine.
