On a beautiful Saturday Autumn morning,I was strolling around Piazza Navona. I noticed this young man playing or performing with his long bubble-generate sticks. Every stick has strings tied to it in different ways to produce different kinds of bubbles. So I held my iPhone 6+ for about half an hour, taking many photos when bubbles came out and beautifully flew around. This photo is my favorite simply because the happy, bouncy and bubbly mood and laughter conveyed from all the children chasing after the bubble. That is why I called this photo "Bubbly Navona".
