With two courts of trampoline flooring, AZ Air Time dares to ask what games of dodgeball would look like on the moon. Kids leap across rainbow-colored mats to try and strike their opponents, heedless of the hubbub nearby, where fellow guests rebound off the surface and slanted walls of the 5,000-square-foot main trampoline. Elsewhere, basketball hoops mounted above trampolines permit players to add midair flair to their dunks, and a cushiony foam pit provides a soft space for safe jumping.

The futuristic indoor park is the brainchild of Barry and Jeff Jenkins, who welcome children to achieve giddy weightlessness in areas grouped by age. Boot-camp sessions for moms also take advantage of how gentle a trampoline is on joints, unlike a 15-person tap-dancing rivalry. During parties, the sound of youthful shrieks bent by velocity fill the air.
