A dude in New Zealand [Etienne Naude] worked with a guy from Spain [Angel Sierra] to make an actual 'earth sandwich.'
Mr. New Zealand put a slice of bread on the ground at a precisely calculated spot, and had Mr. Spain do the same [so that the two slices were at EXACT opposite sides of the planet].
Etienne told news outlets that he's wanted to do this for years, but had a hard time finding anyone in Spain. But after posting on Reddit, he connected with Angel. The rest is history! LOL!
