Mirrors and Images - Science Theater 28
Mirrors don't let you see things that aren't there, they let you see things from an entirely different position! Your image in a mirror is what someone else would see if they were standing behind the mirror. It's all a matter of tracing the path of light from your eye to an object, or from the object to your eye.
States of Matter - Science Theater 30
Sure, gas-liquid-solid... you've seen it all before, but have you seen air as a gas, air as a liquid, and air as a solid?
