Life requires water, which is why scientists fervently search other planets for signs of frozen oceans, faucet handles, and linen yacht pants. Get your watery fix with today's Groupon: for $25, you get four one-day admission passes plus a $20 concessions voucher to Adventure Oasis Water Park in Independence (up to a $56 value).

At Adventure Oasis Water Park, operated by the City of Independence Parks and Recreation Department, a 900-foot long lazy river encircles a playscape packed with water activities for families and kids of all ages. Leisurists can kick up H2O by careening down the 210-foot open flume slide known as the Rattler, the 197-foot Scorpion tube slide, or the family-friendly Sidewinder, which spans more than 300 feet. According to the map and centuries of marine-biology testing procedures, the chutes deposit their drenched live cargo into a swim basin, where they can scale the Cactus Climb wall. For further liquidly adrenaline pursuits, a diving board awaits adventurous parkgoers at Roadrunner pass—a 25-yard lap pool with multiple lanes—and 6,000+ square feet of hydrogen dioxide flood the basin of Buckaroo Beach, a pool dotted with striped, shade-granting parasols.

Puckish park fans replenish their soaked selves at Oasis Grill, a full-service concession area protected by the shade of red umbrellas and by Poseidon's personal fry cook. Water guns, sprinklers, and a monster-sized aqua-spilling bucket further hydrate the park, where amphibious humans splash away during special events such as Chalk it Up and Polynesian Days.
