Folks who attend Nimble Arts’ awe-inspiring circus spectacular Flip Fly Fun! should prepare to see the world from a different angle. The Brattleboro-based troupe transforms Spruce Peak Performing Arts Center into a topsy-turvy big top in which gravity is no obstacle. Onlookers of all ages watch with wonder as world-class performers hailing from outfits such as Cirque du Soleil and Ringling Bros. and Barnum & Bailey dazzle with feats of juggling, acrobatics, clowning and aerial stunts. As the company claims on its website, “The magic begins when the world goes upside down and up in the air!”
