Snap, then surf
Thanks to engineer Karl Pope, surfboards now fit in the overhead bin. Pope's 9-foot-6-inch, 15-pound Bisect Hollow Carbon Stealth surfboard can be taken apart and snapped back together in minutes. Better yet, since it's made of carbon fiber, it's 25 percent lighter and 10 times stronger than glass boards. Available in June.
