I was playing I Spy the other night and failed to guess that A stood for Air.
I protested that you can't see air.
But it was pointed out that heat haze and twinkling stars are a result of refractive index variations, so therefore you can see air.
Which got me pondering, as G for Glass is probably legitimate in I Spy.
So now I can cannot decide, in any scientifically defendable way, whether A for Air is cheating or not.
Or maybe I am not supposed to take I Spy so seriously.
