Originally built by NASA to test the effects of weightlessness on manatees, vertical wind tunnels have since become popular practice areas for professional skydivers, barbershop quartets, and other death-defying thrill-seekers. Simulate floating in the sky and work on your four-part harmonies with this Groupon.
$50 for a Three-Flight Indoor-Skydiving Package with DVD ($107 Value)
The first flight of the package is an introductory flight and once the indoor skydiver feels comfortable, the remaining two flights are performed back-to-back.
At iFLY, "indoor flying" means something way cooler than jumping on your bed at home. There are helmets involved. Here's how it works: you show up, suit up, and go through an orientation lesson with expert instructors before lifting off in an air column powered by a combined 1,600 horsepower worth of giant fans. The column is forceful enough to simulate the experience of dropping through the sky, even though flyers are just inches from the ground. As with outdoor skydiving, the flying experience lasts for about a minute but with the earn your wings package flyers get two flights, and may be able to execute turns and tricks at the instructor's discretion.
