Scientists agree that children are our future, which is why most children are sealed in time capsules with a flashlight and a stack of magazines. Give a child something he or she will really dig with today's Groupon at Active Learning Centers at the Allentown location in the Lehigh Valley. Choose from two options:

• For $99, you get a kid's birthday party (a $315 value).
• For $10, you get three, two-hour open bounce passes (a $21 value).

Active Learning Centers proffers the physical fun of interactive activities such as martial arts classes, rock climbing, and bouncy inflatables in a confidence-boosting environment appropriate for all ages. Build a birthday party for up to 15 children with the center's own Ping the Panda, where your child can choose between a 45-mintue rock-climbing romp or boisterous bounce party, which can include frolicking down inflatable slides and spring boarding off cushy jumping pads. Nourish rambunctious rug rats with a cake, pizza, soda, and a visit from the venerable Ping the Panda himself, and as part of the standard party package, you also get 18 invitations, room decorations, a Ping T-shirt for the birthday kid, a group photo for you and your guests, and a gift certificate for each partygoer for three martial arts classes or a free open bounce session (a $315 total value). Those looking for two-hour increments of kid-pleasing activity can opt for three bounce sessions good for inflated shenanigans rivaled only by the Stay Puft Marshmallow Man’s weekly yogalates.
