For every action there is an equal and opposite reaction, which is why every time a human attempts to fly, a bird attempts to drive a stick shift.

Xtreme Trampolines safely sends guests of all ages ricocheting off the floors, up the walls, and into the lower stratosphere. The 45,000-square-foot indoor facility houses five giant checkerboards composed of commercial-grade trampolines for full-body bouncing. Angled trampoline walls keep customers from crashing into anything but the soft foam pit, and also allow more experienced bouncers to maintain their momentum and pull off-the-wall flips, somersaults, and astral projections. On the dodgeball court, players use dead-drop ducking and high-flying dodges to avoid opponents' throws for an immediate counterattack. Xtreme Trampoline injuries are usually minor and occur very rarely, at a much lower rate than common team sports such as baseball, soccer, or rattlesnake toss. Check the schedule for weekly open hours.
