I am 16 and a sophomore in high school. I believed from the time I knew what an atomic bomb was to today (August 19th 2008) that when things in close proximity to the blast are vaporized, that they just disappear. I was informed by my chemistry class and teacher that they do not, in fact, "turn into air" rather they are converted into extremely small particles that are lighter than air. Silly me.
