Sierra and Naude have created an "Earth sandwich" - by placing bread on precise points, either side of the planet, at the same time.
Naude from New Zealand wanted to make one for years, but had struggled to find someone in Spain, on the other side of the globe.
Two months ago, he posted on the Spain section of the online message board Reddit. He got "a few replies" and found one person close to the precise location.
The men used longitude and latitude to make sure they were precisely opposite.
According to World Atlas, only around 15% of "territorial land" is antipodal to other land. Naude only had to travel a few hundred metres to find a suitable public spot on his side of the world. Mr Sierra had to travel 11 km .
