A Polish soap bubble artist performs on Dionysiou Areopagitou Street in the historic center of Athens. Piotr Ostrowski, 31, gave up his job at a recording studio in Poland six months ago to travel the world, funding his journey along the way by putting on soap bubble spectacles in public spaces using two selfie sticks and what he calls his ‘magic’ soap mixture. Ostrowski has been in Athens for a month and plans to stay at least another two weeks before continuing his journey, performing on the popular promenade every day until sunset.
