Adding water results in less floury biscuits, larger foam dinosaurs, and slides that won't give a shirtless cousin friction burn. Douse yourself in smooth-moving good times with today's Groupon: for $13, you get a one-day family pass good for up to two adults (up to a $16 value) and two children (up to a $12 value) to Silliman Activity and Family Aquatic Center in Newark (up to a $28 total value).

Silliman's indoor aquatic center provides hours of fun and exercise with a fitness studio, gymnasium, and teen area. Twin water slides tower 20 feet above the pool deck, intertwining as they deposit paddlers into the pool banks. Curling through the 32,000-square-foot cerulean canvas, a 245-foot lazy river enables slow-motion sightseeing of the fountains and freestylers. Four lap-swimming lanes segregate speed swimmers from leisurely water treaders, a children's activity pool provides pool-based activity space for children, and a warm-water spa soothes aches and sore muscles with pleasantly heated water. Body builders can banish beads of sweat in the gymnasium or fitness center, which is populated by cardiovascular and weightlifting implements. The community-minded center also has a teen area that offers youth school-service hours.

Lifeguards and locker rooms rank high among the center's amenities, providing patrons with both peeled eyes and privacy. Check the pool hours prior to shimmying into spandex to ensure that each water wader has sufficient splash time.
