Like combat maneuvers and delivering a baby, circus acts are most exciting when performed in flight. Harness mid-air exhilaration with today’s Groupon: for $15, you get two circus-arts classes at Aerial Space (up to a $32 value).

Aerial Space's instructors are former circus performers dedicated to the art of airborne motion and festive performance. Students of all ages and levels of skill soar and juggle their way across a schedule laden with eight jocund classes. Glide under the watchful eye of experienced trapeze artists, skyrocketing upward like a geyser of oil and floating downward like oil commandeering a kite. Burgeoning flyers ease their way through Aerial Silks or Aerial Basics, which sample a smorgasbord of height-happy hobbies including static trapeze and hoop. A two-hour supervised open workout offers creative control over the equipment for students with at least one class of experience. Aerial Bootcamp carves muscle tone using suspended slings and silks to perform a workout previously possible only in the International Space Station weight room. Cardiovascular endurance complements newfound coordination crafted in the school's juggling course, and kids' aerial classes ensure pint-size pneumatics get their high-flying fixes.
