A full moon only lasts for a few minutes as the earth, sun and moon are constantly moving. In fact, technically, it is only ever 99.999% full. At the time of asking my answer showed the accurate 'phase'.
You obviously know a lot more about it than I do, Zacs. I say daft things like , 'It's a full moon again tonight, just like last night' Shows how much I know.
Zac, I love these sort of discussions that regularly arise over a pint. A favourite subject in our pub is can you actually be buried at sea? when burial implies digging a hole, putting some thing in the hole and then filling the hole up again.
