All throughout Eastern Europe, I came across many different street entertainers, from violinists to living statues. But my favorite were the bubbleologists – bubble performers. Children (and adults) would gather around and laugh and try to catch them. The sight was mesmerizing. This photo was taken in the main square of the Old Town of Kraków, Poland. The wind carried the bubbles high into the air, dancing around the spires of Town Hall Tower and coloring the sky.
