Physicists have determined that the best way to subdue wall-bouncing photons is to let them loose until they need a nap. Apply the latest scientific findings to your kid’s playtime with today’s Groupon for Lindsey’s Entertainment and Lindsey's Bouncing Tigers, the latter of which is located on Siegen Lane, just off Airline Highway. Choose from the following options:

• $40 for $100 worth of spacewalk, tent, game, and concession rental from Lindsey's Entertaiment
• $35 for 20 passes for use during open-play hours at Lindsey's Bouncing Tigers (up to $150 value)

Lindsey's Bouncing Tigers provides spring-legged youngsters with an indoor playland of squishy inflatables. Safe, clean, and well-maintained, the bounce zone is primed for open play sessions on Tuesday and Thursday, 9 a.m.-12 p.m, and Wednesday, 4-7 p.m. Kids with suspended drivers' licenses can also import the playtime into their own backyard or secret garden by renting games ($9.95 and up), spacewalks ($79.99 and up), tents ($150 and up), and concessions ($50-$75) from Lindsey’s Entertainment.

There is a standard $50 or $100 delivery and set-up fee for rented equipment, depending on the amount of equipment rented, that this Groupon may be applied toward. Though Lindsey's Entertainment has delivered as far away as Texas and Mississippi, delivery fees for long-distance delivery are determined at the time of rental.
