If houses were really made out of springy, inflatable materials, sporks would be outlawed and knitting grannies would inspire apocalyptic terror. Indulge in safe, recreational bouncing with today's Groupon: for $12, you get three unlimited day passes at Jumpin' Jax Bounce Arena (a $24 value).

Founded by jaunty moms Joan Blackmer and Kelly Ramirez, Jumpin' Jax provides 10,000 square feet of air-filled entertainment treating children, toddlers, and parents to seven inflatable bouncers, slides, and obstacle courses. Kids and their adult servants can mimic buoyant British barons in the classic jumping castle or compare fabric friction while racing down the 25-foot-long double slide. Obstacle courses like the Fire Truck 3-1 Slide and the 360-degree Adrenaline Rush II combine jumping, sliding, and climbing for the ultimate funfest or life lesson in angry kangaroo evasion. Toddlers being toted along on the inflatable excursion can enjoy a puffed-up play date of their own in the Laugh N Learn course, a special area designed specifically for pint-sized pouncers, and parents can feel assured knowing that all equipment at Jumpin' Jax is cleaned and sanitized daily.
