Children who are encouraged to express themselves grow up to have confidence in their ideas, making it far easier for them to woo investors with business plans for candy-necklace jewelry stores. Inspire future entrepreneurs with today’s Groupon: for $8, you get three pop-in play times at Pump It Up (an $18 value). Choose between two locations: Austin or Round Rock.

Pump It Up's inflatable arenas rocket sock-clad striplings around with a plethora of kid-friendly indoor bounce pads. During three pop-in play times, kids age 2 and older leap around gargantuan air-filled bounce houses, skip down air-filled slides, and slither as swiftly as snakes coated in bacon grease through an air-filled obstacle course. The facilities' giant halls are climate controlled and maintained according to strict safety standards and rigorous guidelines.

Since jumping is an exciting method for burning calories, a lively lark through the inflatable fun houses will cause youthful energy to melt off faster than ice cubes thrown in a running DVD player. Parents bounce for free during pop-in, so childless adults who want to play will need to borrow a neighbor’s kid or win one by collecting soda tops. The calendars for the Austin and Round Rock locations are updated weekly. Check back or call for available pop-in play times.
