Opposites, Unite!

You walk across the living-room carpet, scuffing your feet, to turn on the light switch and ZAP!  You've been hit by static electricity.  That very same static electricity  holds the atoms of table salt into the form of those little white cubes.  How does it work?   It's all due electric charge, a fundamental property of [...]
