tannerite.com, for what its worth.
I suspected as much, but typed the beginning of the company shipping policy shown on the video into google for confirmation:
http://www.google.com/search?hl=en&q=%22we+ship+in+low+profile+packaging+boxes+to+prevent+unwanted+attention%22I am familiar with it through reading, but have never bought or used the stuff. Many of the explosions on the video especially the last one, were augmented with a flamable substance, and when you read on the website what the chemical engineer has to say, the understanding of how the stuff works will confirm as much. I urge everyone to read what he says here:
tannerite.com/she_exploding_targets.html
The news report, while nicely done for shock value, is quite misleading. The explosions in the video, toward the end for example. The news report claims that mcveigh used amonium nitrate to blow up the murrah federal building, which is true, but he didn't use tannerite, he used a mixture of ammonium nitrate and deisel fuel, which is a completely different and far more powerful animal than tannerite. The explosion that the news guy set up which sent sent the 20 pound plastic barrel 25-30 feet in the air is another example. I can remember doing the same thing back in the day to a steel barrel, with old school silver salutes, and years later with the original m-80, and having it go at least 30 feet in the air.
Being alarmed about this stuff is everyones perogative, but if your going to be alarmed, be alarmed based on fact, rather than being misled by the sensationalistic video linked in the OP.
