Before bouncy play centers were invented, children disposed of excess energy by splitting atoms and throwing light bulbs in the trash. Encourage a bouncier method of energy expenditure with today's Groupon: for $16, you get three open-jump sessions at Jump Ronkonkoma (a $32.42 value including tax).

Jump Ronkonkoma is a springy, indoor play palace bursting with inflatable bounces, slides, and games. Two gargantuan rooms each corral three to four inflatables to construct a rainbow of bouncy bigness that gives sock-sporting kids the chance to scale a rock wall, sojourn through overstuffed obstacle courses, and boomerang through the air. Classic arcade and video games, an inflatable basketball center, and trampoline speed-chess fill up the game room with more nonstop fun. Jump's open-jump schedule provides hours of dynamic ricocheting in a climate-controlled environment that's sanitized daily and where safety and beating the kangaroos in the next space race are the top priorities.
