A South African man on Saturday successfully flew across the sea from Nelson Mandela's apartheid island prison using helium-filled giant party balloons.
The six-kilometer (3.7-mile) crossing, to raise funds for a children's hospital named after the country's former president, was the first stunt of its kind from the historical site.
Matt Silver-Vallance, 37, took around an hour to float across the Atlantic Ocean from Robben Island while harnessed to a mass of mufti-coloured balloons in grey, drizzly conditions with low visibility.
Making his way wearing a wetsuit, he floated a few meters above the sea, with controls for flight including bags weighted with water and an air gun and make-shift spear to pop balloons.
"Wow, that was crazy," he said, saying he felt "unbelievable" after landing in a rubber duck around 300-400 meters (985-1,310 feet) from shore once the balloons were released.
"Don't try this at home," he quipped.
With no test run ahead of lift-off, a total of 160 balloons were inflated on the island early Saturday morning, with several popping ahead of departure.
