Without trampolines, kids would have to find other backyard diversions, and electricians would have to resort to ladders to repair phone lines. Aim high with today’s Groupon to Hang Time Sports, located in XSI Factory in Lehi. Choose from the following options:

• For $8, you get one hour in the trampoline park for two people (a $16 value).
• For $15, you get one hour in the trampoline park for four people (a $32 value).
• For $29, you get one hour in the trampoline park for eight people (a $64 value).
• For $199, you get a two-hour private-party rental of the entire facility (a $410 value).<p>

All jumpers must register online and bring a signed liability waiver on their first visit. Bouncers disregard outdated notions of gravity as they cavort across Hang Time Sport’s 2,500-square-foot trampoline playground filled with springy surfaces, foam pits, and a scalable indoor rock wall. As adults and children bounce off of horizontal and angled trampolines, chaperones and bemused kangaroos look on from a second-floor observation deck. Otherwise, during private parties, swarms of up to 25 jumpers stake a claim on the entire facility as staff members help celebrations run smoothly. Furthermore, party tables can host refreshments provided by Hang Time at special group-package rates (not included with today’s Groupon). To ensure a safe session, Hang Time advises all participants to remove foreign objects, such as keys and electronic devices, from their pockets and to wear appropriate attire free of hanging zippers, loose belts, and unsheathed katana swords.
