Hey! This is interesting but I’m definitely giving this a shot.
So let’s start with ink.
INK- ink mixed with water is not going to thicken the water or make it change shape, it will more than likely change the color of the water and you will be able to see the train of the ink while in he water.
PEBBLES- When you put pebbles inside water it is going to make the water more dense. Pebbles are a sort of matter, so when put in the water they will take up space and likely sink to the bottom.
SALT- I’ve actually tried this and this is also what the ocean is made of. Salt and water.
The salt will probably dissolve and give the water a foggy look. And of course it will definitely not have the same taste.
I hope my answers helped and that this was what you were looking for. Again, I was just trying here... I didn’t research this. This is out of experience. I’m glad to help with anymore questions.
