Children who aren’t allowed to jump and bounce seek higher elevations in riskier ways, such as giraffe-rustling and pole-vaulting across busy highways. Placate your progeny’s urge for altitude with today’s Groupon: for $12, you get four pop-in playtimes (a $28 value) at Pump It Up in Fort Collins.

Pump It Up's indoor inflatable arenas exercise and entertain bouncy children, while giving pooped-out parents a much needed break. During four fun-filled pop-in visits, children can leap around gargantuan air-filled bounce houses, skip down air-filled slides, and slither like snakes covered in bacon grease through an air-filled obstacle course. Pump It Up’s giant indoor air arenas are climate-controlled and maintained according to rigorous guidelines enforced by a well-trained staff and local police. 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.

From expert installation and anchoring to insurance coverage and rule enforcement, Pump It Up holds itself to strict safety standards. Since jumping is an exciting method for burning calories, a lively lark through Pump It Up’s inflatable fun houses will cause youthful energy to melt off faster than ice cubes thrown into a running DVD player.
