As if walking on a tightrope weren’t hard enough on its own. Ariana Wunderle, a senior at Bellows Falls Union High School in Vermont unofficially broke a Guinness World Record by walking nearly 640 feet on a tightrope while wearing four-inch heels. She climbed onto the six-foot-high tightrope on Monday (May 16th) in the school’s gym and walked across the rope 52 times. Evidence from Wunderle’s record attempt, which was part of her senior project to raise money for nonprofit youth organization Circus Smirkus, is being submitted to the record-keeping organization for official recognition.
