The first parachute was invented when Jack, tumbling haplessly from his titanium beanstalk, used a purloined pair of giant underpants to steady his fall. Safely freefall without a burdensome apparatus with today's Groupon: for $69, you get a five-minute flight and t-shirt from Niagara Freefall Indoor Skydiving, located at the Niagara Freefall & Interactive Center in Niagara Falls, Ontario (a $141.25 value).

Niagara Freefall Indoor Skydiving straps thrill seekers into its environmentally controlled indoor vertical wind tunnel for an adrenaline rush akin only to skydiving. This trip to zero Gs begins with a 25-minute pre-flight training that maps out safety, flight suit assemblage, and beloved Smothers Brothers routines. Niagara Freefall's five-minute flight elevates air walkers in an air chamber sprawling 20 feet high and 12 feet wide as it faithfully mimics pulling a ripcord and hopping from a plane. As the 140 mph wind speeds gently blast your body for 300 earth-defying seconds, place yourself into the mindset of a flying squirrel or attempt to mime eating a banana. The wind tunnel's padded walls and floors ensure safety as a professional instructor monitors all activity. Up to five people may participate in a group, providing the ideal excuse to get matching Jackson 5 tattoos after the exhilarating plummet.
