With summer setting in, homework-hungry schoolchildren must find a new source of both academic and fantastic thrills. Today's Groupon functions as a handy substitute for studious activity: for $10, you get a one-day extreme wristband for unlimited go-karts, mini golf, laser tag, Spaceball, Jumpshot, and Water Wars at Papio Fun Park. This indoor and outdoor fun factory churns out a surplus of fun and more fun things, such as fun, seven days a week from noon until 11 p.m.

Ever since professional basketball stadiums were moved to orbiting space stations, one of the only places to play old-school trampoline sports has been Papio Fun Park. Let the youngsters pounce like lunar mountain lions on the spring-loaded Jumpshot court, which pits opponents against each other in an airborne battle for basketball supremacy, and its futuristic equivalent, Spaceball, a trampoline-based hybrid of dodgeball and basketball. For additional creative competition, check out Water Wars, a water-balloon-based battle zone complete with launchers and temporarily dry opponents.

Traditional earthly activities, such as miniature golf, laser tag, and go-karts, are also included with the extreme unlimited wristband. For the go-karts, children under 8 years and/or below 50 inches must ride with an adult. Children young and old are welcome to play all day and divide their rides and games up however they please, as long as they do not exceed the limit of unlimited fun.

Must be at least 8 years old and 50 inches tall to drive go-karts, but may ride with parent or guardian driver otherwise.

All outdoor activities are weather permitting.
