The other morning in Christchurch I threw back the hatch and this is what I saw
never seen a sky like it
It only lasted a few seconds and by the time I had my trsousers on it had gone
looks like the World is upside down!
Once when teaching; I had a student heating Iodine in a fume cupboard, I looked out of the lab window to a purple sky and slight mist at sunset. “look at all that pollution you are causing” I said to the student. (iodine vapour is purple).
