How do you improve the trampoline? Easy, just build one on top of a giant inflatable platform. The Aviva Sports Orbit ($3,500) may be intended for water parks and camps, but if you’ve got the cash, think of this beast as the ultimate lake house accessory. The mondo aquatic trampoline measures 25 feet in diameter and can support up to 1000lbs of double-jumping, pancaking, and back flipping goodness. Of course, if tricks aren’t your thing — the potential for Jackie Treehorn-style sightseeing is always there depending on your guest list.
