The stone jumping is one of the famous traditional culture from Nias known as Hombo Batu in Nias language where the man will jump over a 1.2 meter rock stone. It was the culture they have when in the previous time they use that to jump over the enemy gate using their costume to disguise while doing so.
I have a chance to watch the culture festival in the village where children have the jumping competition, start with the low height and getting higher and higher.
