If you open front and rear windows on one side only you'll find you won't be able to recreate the effect.

lived in the NT for over 30yrs during a cyclone we were told if its heading towards the front of the house always leave a window open at the back of the house because they reckon during cyclone Tracy a lot of house were lost due to pressure in the house not being equal to the outside never understood physics but they imploded/exploded because of this!!
