Physicists estimate that 47% of the energy in the universe is stored in stars, and the other 98% rages inside human children. Release your child's unyielding cosmic energy with today's Groupon: for $12, you get admission to a Friday-night open gym and open bounce at The Funplex of Gulf Breeze (a $25 value). Open-gym hours last from 6 p.m. to 10 p.m., and bounce-house and rock-climbing-wall hours last from 6 p.m. to 8 p.m. Bounce rooms and the rock-climbing wall are limited to children 10 years and younger.

The Funplex of Gulf Breeze's three-floored, 28,000-square-foot edifice enthralls tumbling tots with inflatable bouncers, a rock-climbing wall, and an entire floor dedicated to gymnastics. Six vibrantly colored bounce houses speckle the bottom floor and satisfy connoisseurs of antigravity with plush pastures of airy canvases and slides. Otherwise, a miniature rock-climbing wall introduces guests to the art of coordinated alpining, and the top floor's cheerleading and gymnastics area provides a space to hone back flips and Olympic-grade log rolls. A batch of fitness equipment provides a host of exhilarating surfaces, including a trampoline, foam pit, and balance beams stationed over imaginary lakes of magma. Although not included with today's Groupon, a snack area replenishes low fuel tanks with pizza, popcorn, and drinks.
