The actual implosion will last no more than a few seconds. Advanced Explosives Demolition Inc. will generally place many small explosive charges (usually weighing a few ounces each) at critical locations on the structure. These charges will detonate at intervals to dominate the direction of fall.

With respect to 'feeling it', it is amazing how sensitive the human body is! Whether or not you 'feel it' will depend upon where you are at the time of the implosion. If you are standing downwind, you will think you feel it when you hear the noise created by the charges being detonated. Actually, you won’t. Nor will you feel the vibration from the detonation of the small charges or the fall of debris at ground level. Seismographs will be used to record the actual vibration of the implosion operations and the falling debris.
