it'll get hot.
Water dissolve and transport salt.
It lowers the boiling point, and makes it "salt water".
Your feet get wet.
~When you put salt in potato and then put it in the water cup, there is low water concentration in potato and more concentration in the cup of water. Due to this concentration gradient water moves from the cup into the potato by osmosis.
Your skin gets wet and salty
it rusts coins faster because it has salt in which you put on fish and chips... :)

Salt will dissolve in water. Adding salt will lower the temperature of water by a few degrees Celsius as well as lower the freezing point.
