Appearance: It is see-through, and it wobbles around in the glass. It sort of distorts what you see through it. Occasionally there is bubbles in it, and they look like little tiny marbles. Even if you so much as gently tap the table it is on, it vibrates. Like curved mirrors, if you look through water, sometimes the things behind it look stretched out, sometimes they look squished down.
Smell and Taste: It smells fresh, and almost chlorine-y. It smells like it tastes, natural and nothing else. It seems like it would taste refreshing, judging from the smell. The taste reminds me of lemons because it has a hint of that bitter, sour taste. It tastes natural, or at least we would imagine it to be. It seems like it doesn't have anything added to it, because it has only one taste. It never tastes different, like brazil nuts and walnuts.
Texture: It feels smooth and soft. When touch water, it is not like touching a brick. You have more freedom feeling water, because you can stick your hand into it, unlike any solid. When you take your hand out, some water stays on and decides to hitch a ride. Water can feel cold or hot, and is usually refreshing to feel.
Ice, on the other hand, makes a crushing noise when you move it around. It is not clear, but it is not completely opaque either. It smells cold, and tastes like a cold, bitter lemon coated in water. It feels really cold, and is both smooth and rough.
Vapor makes a "wooooooh" noise, and sounds like air. It is clear, but you can see it from close-up. It smells like terrariums in zoos. It tastes like how it smells. It is cold
