Like keeping a great-grandad's musket above the fireplace or a jar of capers in the fridge, having access to a room filled with trampolines gives you the power to shake up a dull dinner. Pop the seal on pent-up adrenaline with today's Goupon: for $16, you and a companion each get one hour of jump time and eight minutes on the back-flip machine at Rebounderz Indoor Trampoline Arena in Longwood (a $34 value).

With nearly 7,500 square footage of pure jumping space, Rebounderz launches friends and families into the stratosphere before beckoning them safely back down to the bouncy, vinyl-clad Earth. After checking in, participants receive proper safety training and are outfitted with equipment such as padded helmets, safety shoes, ankle braces, and gravity repellant. After jumpers are decked out in all the proper gear, an instructor guides them through the proper hopping techniques and sends them on their way to test their toe wings. Once inside, leapers are free to photon their way through the arena, bouncing against walls and catching air from the floors for 60 exhilarating minutes. In addition to admission to the arena, Groupon holders get eight minutes on the back-flip machine, a four-person kidapault that lets users securely flip, spin, and literally harness their energies.
