The first parachute was invented when Jack, tumbling haplessly from his titanium beanstalk, used a purloined pair of giant underpants to steady his fall. Glide to earth safely with today's deal: for $120, you get a tandem skydive jump with an experienced instructor (a $195 value) from Skydive Sebastian, located in Sebastian.

A member of the United States Parachute Association, Skydive Sebastian treats thrill-seekers of all experience levels to the pulse-pounding adventure of an aerial descent. Each partnered plunge begins with a brief briefing on the ground to help newbies learn the ropes of safe diving, as well as how to exit the airplane in a manner that doesn’t involve bacon grease. After the primer and subsequent airplane ascent, strap yourself to the birdlike body of your experienced jumpmaster and begin your journey earthward with a nearly minute-long free fall demonstrating Einstein’s first law of gravity. Once you hit 5,500 feet, or approximately eye-level with an average NBA basketball player, the natural phenomenon of parachute deployment will turn your fast-paced fall into a gently wending sky cruise that lasts for approximately five minutes before your shoes grudgingly reunite with the ground.

Throughout the descent, skydivers can fill their peepers with one-of-a-kind views of the beauteous blueness of the Atlantic Ocean and the hard-candy shell of the Florida coastline. Divers also have the option to purchase photographs and video of their dives (not included with today’s Groupon), allowing them to show friends evidence of their airborne mettle.

Although Skydive Sebastian sometimes features a discounted price online, this Groupon still offers the best deal available.
