Question: Why does the charged comb attract water, salt and other objects toward it?

Answers

Question 1: In the United States, between 75 to 100 Americans are hit and killed each year by lightning

Question 2: house, car and cave

Question 3: The comb attracts objects for the same reason the balloon "stuck" to the wall.  The attraction between opposite charges. When you rubbed the comb, you gave it a negative charge, like the balloon. And like the balloon, it will also attract the positive charges in objects, like in the water or your hair.
