A playground can be the site of a first birthday party, a first transatlantic paper-airplane flight, or a first doctoral dissertation on the geothermal impact of teeter-totters. Make a scientific breakthrough while breathlessly jumping with today's Groupon: for $150, you get two three-day summer-camp sessions at BounceU Farmingdale (a $300 value). Sprightly bouncers must wear socks in order to play.

Named 2011’s Best Camp on Long Island by the Long Island Press, BounceU Farmingdale’s summer day camp transports kids to an inflatable, climate-controlled playground where they bounce from side to side in a safe, stimulating environment. From 9 a.m. to noon on Tuesday, Wednesday, and Thursday, kids can imagine they're synchronized leapers in Michael Flatley's Riverbounce as they carom around the inflatable stadium, expending energy and cultivating creativity with every leap. From giant-gloved boxing jabs to bounce-assisted slam dunks, exercise meets imagination through games and artistic activities designed to engage young minds. While campers trample through inflatables, the attentive BounceU Farmingdale staff monitors the rebounding playground at all times, ensuring that the facilities are safe, clean, and thoroughly buoyant.
