They dump in the salt getter, pull it out, remove the salt, dump it into the water again, continue until all the salt is gone. Maybe they capture more salt molecules than is shown in the model?
Salt is to be admired for its atomic beauty and proof of order in the universe. Our astrophysicist friend Adam Frank says you can find some good news in something as simple as a single grain of salt.
