Picture yourself as the guy who is about to flip the switch just seconds before the blast is supposed to take place. For the past eight weeks you have meticulously planned out the demolition of the old deteriorated Clark building which is supposed to fall mostly onto an adjacent parking lot. Everyone is a safe distance from the site and the countdown is running down: three...two...one... you flip the switch...
- At speeds of up to 21,000 feet per second, the charge is sent down the cord to the explosives which have been placed at strategic points in the building.
- The first charges are set off, the dynamite and RDX going off almost simultaniously, creating powerful air compressions to destroy the supports. The RDX compression creates 3 million pounds of pressure which cuts a hole through the 10 inch-thick steel supports at a rate of 27,000 feet per second.
- Shock waves from the blast radiate from the site at the speed of sound, causing everything nearby to shake and rattle.
- Having nothing left to suport it, the section of building begins to fall and crumble under its own weight while the second round of charges go off.
- This process is repeated several more times until the entire building begins to fall in unison -- a massive dust cloud is formed high into the air while the air within the doomed structure escapes harmlessly from the sides.
- Because some of the building's walls were only blown from one side, they begin to topple to one side towards the parking lot as planned.
- Within 30 seconds of flipping the switch, the once 15 story low-rent high rise is nothing more than a pile of rubble.
AND THAT'S HOW IT IS DONE!!!
