 It's these water crystals. They just look like little crystals. When my family had the nursery up in Maine, the family patch, we used to do sample jars in the front of the registers where we'd put some in a little bowl, water it, and let it expand. Obviously, everybody had to put their hand in it, and they'd be like, what was that? That's soil moist. They would show the bag that's right next to it and say, oh, this is only a teaspoon of that.
