Here's a question I was just asked... apparently my cousin has a bet on and I suspect he's going to lose. ;)
From the moment the sun first touches the horizon at sunset, how long does it take to fully set? (Horizon meaning, for this question, as seen at sea.) Apparently my cousin reckoned 1 1/2 minutes! :oo:
Here in Vic it's almost impossible to go and actually measure, 'cos there's always land to the west. Bloody westerners, always getting in the way... :p
