Like vitamin gummy bears, baby formula, and intense sibling rivalry, the satisfaction of a surprise squirt-gun attack is something fully developed humans never outgrow. Indulge your inner or real child with today's Groupon: for $14, you get a five-attraction pass at Adventure Landing, an entertainment utopia with exciting activities on both land and water (up to a $26.99 value).

A family-fun park that aims to engage thrill-seekers of all ages, Adventure Landing offers attractions that span the full spectrum of silliness. Race on go-karts in front of NASCAR scout audiences, make a mark on frenemies in laser tag, saunter and swing on the mini-golf course, or battle adversaries in bumper boats outfitted with squirt guns. Attempt each feat before going back for one last round of your favorite, or use them all on a five-act laser-tag rendition of your favorite Ibsen play. The freedom of choice applies to how you use your five attractions; however, you must expunge the fun out of the frenetic frippery in a single visit, making today's deal a convenient way to happily exhaust overenergized tweens and tots.

Amusement parks are a more active alternative to screen-heavy childhood hobbies such as text messaging, video games, and office temping. Get this Groupon to burn calories, bond with the family, or show off the bumper-boating skills you used to sink the Spanish Armada last summer.

Though Adventure Landing sometimes offers other discounts online, this Groupon still represents the best deal available.
