'Earth sandwich': two men, two slices of bread and 12,724km of filling

Men in New Zealand and Spain calculated longitude and latitude to perfectly align both slices

An Auckland university student has created an "earth sandwich" with a stranger in Spain, after a long search for an accomplice.

Etienne Naude, 19, placed a slice of white bread on the ground at Bucklands Beach in Auckland, using longitude and latitude to ensure he was precisely opposite a volunteer he had found in the south of Spain after posting for help on Reddit.
