Romanian man Flaviu ‘The Extreme Unicyclist’ Cernescu performed this death defying stunt for a episode of the World’s Most Talented.
Flaviu rode his unicycle on a super thin railing that acts as a safety measure for pedestrians crossing. Flaviu did so without any safety equipment. If Flaviu were to fall from the railing he would plummet 544 feet to what would likely be his death.
This is not something you want to attempt at home that’s for sure. I would get nauseous just looking over the edge, none the less hopping on a unicycle and riding the railing!
