Although it may seem trivial, an explanation for why people, especially children, enjoy bubbles so much could provide important insights about the human brain for issues such as visuo-spatial cognition, emotions, and evolution. Regardless, I was also able to appreciate the above scene of several young women making bubbles at Nianjia Lake in Changsha' Lieshi Park for the calm moment it provided.
And as I write this post, I am also keeping an eye on another "bubble". Felix Baumgartner is currently being carried up in a pressurized capsule by a balloon that took off in New Mexico for his attempt at a record-breaking balloon ascent and skydive. His jump might not be a calm moment, but best of luck to him on his inspiring feat.
