Why doesn't salt water and fresh water mix?
Salt water and fresh water do mix, when you mix them the salt water becomes more dilute meaning there is slightly more water then salt then there was before. If you want to witness them mixing for yourself, the experiment you could do is quite simple. Just take salt water and dye it one color and take fresh water and dye it another. Then just pour the contents of both into a glass, stir and wait a few hours. You'll find that the salt water which is dyed the one color does not separate from the fresh water which you dyed another. Salt water and fresh water are really just two types of the same thing, the only difference between the two is the type of impurities present. Those impurities defuse into purified or fresh water as easily as cigarette smoke diffuses into the air.
