Salt, Anyone?

Today I checked my science experiment and I was startled by what I saw.  IT WAS FILLED WITH SALT!!!!!!!!!!!!!!!!!!!!!!  I didn't think that it would be that full of salt.

The salt is left behind and stuck to the walls of the cup and the water evaporated into the air.                                        

                                                The water level is waaaaaaaaaay lower.

                                                                     That's a lot of salt.
