Spitball technology has come a long way since its invention in 1982. Initially a spitball was made of saliva-soaked paper and propelled by the combination of an empty pen and breath. In 1999, an important discovery irrevocably altered the spitball landscape. Now spitballs are shot with semi-automatic CO2-powered weapons instead of empty pens. And due to the increasing concern for deforestation, spitballs are made out of a more renewable resource: thin-skinned, paint-filled gel caps. Check out the enormous advancements in spitballs at Action Paintball Park with today’s Groupon.

If you didn't know any better, it would be easy to assume that The School of Shred is a place to learn guitar, or at least a place to practice the art of destroying important documents. Instead, the school teaches its students how to shred through waves, shred across pavement, and shred down mountainsides. It's a fitting business name for owner Corey Oswald, who has seemingly spent more of his life moving on some kind of board than on his own two feet. Corey has more than 20 years of experience surfing, skateboarding, and snowboarding. But today, and for nearly a decade now, he helps others get their shred on by offering group and private lessons in all three sports.

The ring of international flags that circles Allen & Sons Table Tennis Club is more than just a decoration. It's a testament to the sport's global popularity and the club's international coaching staff. A highly decorated roster of coaches conducts lessons at the club, led by Fovad Kaseb, former coach of Iran’s national table-tennis team, and Bella Livshin, a US Open and US Nationals champion who has been coaching since 1968. The instructors lead beginners and experienced players through drills on eight Butterfly Centerfold tables, each approved by the International Table Tennis Federation for tournament play. Players enjoy the air-conditioned space with an olympic-style floor designed for table tennis as they work up sweats rallying with opponents or practicing volleys with the Newgy robot—a system that serves balls across the table to the player, catches them in a net upon return, and can never feel emotion. Allen & Sons also offers a live video feed of their club.

As part of its mission to cultivate Southern California’s native flora, the Theodore Payne Foundation encourages Californians to get acquainted with their rootsy neighbors during its introductory four-hour native-plant horticulture class. Horticulturalist Lili Singer reveals which area plants survive droughts and attract native birds and butterflies, and which ones are just Old Man Jasper from the abandoned amusement park wearing a ghost mask. She'll also clarify the concept of plant communities and give you tips on selecting plants for various types of gardens. By the end of the class, green thumbs and their attached humans will gain an introductory-level initiation into establishing new plantings as well as how to encourage plants' growth by pruning them, irrigating them, and attending their piano recitals. Graduates will be eligible for the foundation’s three-part course in native-plant garden design.

Bowling is the great social equalizer—a common ground where grizzled undercover clowns, blue-collar English lords, LARPer librarians, big and tall lingerie models, hordes of hive-minded hipsters, and the other two social demographics that comprise America can unite in common cause and topple a gaggle of stuck-up, inanimate wooden pins. Brunswick has been a household name in this egalitarian pastime almost since the beginning, with a company history that dates back to the 19th century, providing classic American good times to all manner of patrons across the country. And with today's Groupon tying the room together, you'll get to play two games (up to a $10.98 value) in its hallowed halls wearing a pair of freshly disinfected bowling shoes (up to a $4.79 value).
