An Auckland University student has made an "Earth sandwich", after finding a willing helper on the other side of the world.
The symbolic sandwich was created when Etienne Naude, in Auckland, and a man in Spain both placed a piece of bread on a precisely opposite points of the globe.
In between the two slices of bread was a filling of almost 13,000km, or a flying distance of around 20,000km.
To find his fellow Earth sandwich maker, Naude, 19, took to the online bulletin board Reddit, asking if someone in Olvera, Villamartin or Sevilla was keen to take part in the experiment.
After getting a reply from someone in Olvera, southeast of Sevilla, it was game on.
"It was quite hard to organise since it's a 12-hour time difference," Naude told BBC News. "And there's lots of things to arrange, such as the kind of bread, the time, the [precise] location, et cetera."
Naude placed his piece of bread on a nearby beach while his Spanish helper had to travel 11km to find the exact opposite point.
"It's quite tough to find a spot which isn't water on the New Zealand end - and where public roads or paths intersect in both sides," Naude said.
The computer science student posted a photo of the achievement online on Sunday.
To celebrate the feat, he used a laser cutter to burn a picture of the Earth sandwich on top of a surface made of 20 slices of bread.
The sandwich impressed fellow Reddit users.
"I think this is one of the nerdiest things I've ever seen! Very adorable!" wrote one person.
According to the BBC, the first Earth sandwich was organised by the American artist Ze Frank in 2006.
