Made once something like that using 1.4kg of that stuff (don't ask). The pillar of fire was impressive and it burned for about 10 seconds. Even the forest some kilometer away looked almost bright like during daylight. Only after the awe was over realized how dangerous the stuff was, as it managed to vaporize 12 layers of aluminum folio and just about half a meter of earth from under it. I'm willing to bet it could do something nasty to a harddrive though.
