ADVANCE FOR MONDAY MAY 19 AND THEREAFTER - In a Thursday, May 8, 2014 photo, the impact point on a test wall shows damage after a two-by-four board hit it at 100 miles-per-hour during a recent tornado safe room testing exercise at Forest Products Laboratory in Madison, Wis. A team of engineers have been using an air cannon to fire, at 100 mph, 12-foot long, 15-pound southern pine 2-by-4s into specially designed walls made of some of the cheapest wood available. The cannon mimics the forces of an F5 tornado with 250-mph winds. (AP Photo/Wisconsin State Journal, John Hart)
