UK man Tom Morgan, who runs thrill-seeking group The Adventurists, has floated 25km across Johannesburg on a lawn chair strapped to 100 helium balloons.
The 38-year-old Bristol daredevil floated for two hours and reached heights of up to 8000 feet in an adventure that took weeks of planning.
Mr Morgan, who plans to start the first-ever helium balloon race, had to test the durability of his "aircraft" before the competition could be feasible.
"It's going to be a three-day long distance floating adventure under party balloons on a chair of some description, probably the world's silliest dare race," Mr Morgan said in a video posted online.

After plenty of failed tests in Botswana - and just enough helium for one more attempt - The Adventurists relocated to South Africa to start their journey.
"The problem was finding a good weather window and it was difficult to protect the balloons as they kept bursting," Mr Morgan told the BBC.
After two days of filling up balloons, Mr Morgan's perilous journey across the South African landscape was underway.
As the balloons reached 8000 feet the ride began to accelerate very quickly.
"I had to keep my cool and start gradually cutting the balloons," Mr Morgan told the BBC.
Luckily he made it down to the ground safely.
The adventure was compared to a scene from the Pixar film, 'Up', where 78-year-old widower Carl Fredricksen ties balloons to his house for a journey to Paradise Falls.
