Tightrope walking may be one of the oldest acrobatic practices, but one of the youngest practitioners of the art has become spectacularly good at it. 6-year-old Zhang Wang started working on his balancing act about a year ago when his dad came up with the idea to train his little son as an acrobat in order to build his self-confidence and independence. Zhang wang took to tightrope walking, or funambulism as it is sometimes called, like a fish to water and can now balance his way across a wire backward and even blindfolded.
