In London, Ontario, a team from the University of Western Ontario is bringing a fairy tale to life at the Insurance Research Lab for Better Homes.

They don’t have a wolf, but in their “Three Little Pigs” project they are literally trying to blow the roof off, subjecting full-scale houses to pressures that simulate wind forces matching those of a Category 5 hurricane: 200 mph. Researchers are looking to find the sources of structural weakness in house construction in order to improve building design in the future.
