[Dujon] Yes, of course technically you're correct about the full moon - I was using the term in the slightly vernacular sense, meaning the moon when it is as full as it is getting this month, as it were.
Living in Norfolk and often driving through the fens, I have frequently seen "full" moons on the horizion and they never look any bigger than when it is up in the sky. The moon does look huge however when it is a very fine crescent rising just before or setting just after the sun on a red sky.
[Boolbar] Do you have only one good eye? The "moon illusion" is much less if you close one eye (or really only see well out of one), or stand on your head. If you don't want to stand on your head, you could bend over and look through your legs. Noone would think you're strange. Honest.
[flerdle] No-one is normal in Norfolk, so such behaviour would be ignored, or even actively encouraged. I have two good eyes last time I looked, although one looked bigger than the other . . . .
