Does anyone remember "Duck and Cover"?

My mom would wake me up from a nice sound sleep with the clock reading somewhere around 3AM and take me out to the living room where our radio was (this was in the early 1950s and no TV in Las Vegas). There was a man's voice counting backwards, and when he reached zero, the sky - even the air! - changed color; usually purple but green sometimes, depending on cloud cover. This was a great demonstration of the "speed of light". After the AEC started moving the tests underground (and this new contraption called "television" had overwhelmed Vegas), the picture showed the area above the device and you could see it shaking, but no bright flash. Mom had timed most of the above-ground tests to see how much time it took for the little earthquake to arrive, usually 4.5 to 5 minutes.

Something I'll never forget.

The air changed color? Holy cow!
