Posted Oct 25, 2012 by Anne Sewell
In what one engineer described as a "controlled catastrophe", the video shows the careful, controlled demolition of a 150m chimney in Poland.

As the engineer put it, "Nine-hundred cubic meters of reinforced concrete and acid-proof bricks will fall down on the ground. Thus the preparations are really serious. We call it controlled catastrophe. The preparations are very precise and exact."
We watch the engineers preparing for the blast, then the actual demolition, as 200 explosive charges, placed around the base of the chimney, explode and the chimney leans and finally falls.
The chimney was at a power plant in Torun, in Kujawsko-Pomorskie Province.
