You stand among a large crowd of people who have gathered to see an event which has been months in the making. You hear a countdown: "Three...Two...One..." then, after a very short pause, you hear several large "BOOMS," then a loud rumble as a tremendous cloud of debris fills the air. Finally, you stand in silent awe at a pile of rubble that just minutes ago was a twenty story building as everyone cheers on the spectacular show which the demolitions team has successfully put on.

What I am talking about is the demolition of a large structure such as a building, bridge, or tower through the use of powerful explosives. But what really goes on when a structure gets "blown up"? How are demolitions experts able to fall a massive skyscraper in a matter of seconds? What role does physics play in the process? This site investigates how important physics is in the field of demolishing a building through the use of explosives. To start your tour, click on the bomb below.
