I asked the same question some years ago:

> [Blasting caps](http://en.wikipedia.org/wiki/Blasting_caps) contain a small amount of sensitive high explosive material and a triggering mechanism, and are used to cause the detonation of a much larger amount of less sensitive high explosive. Question: how dangerous are blasting caps themselves? If I hold one in my hand while it detonates, will I reliably: -shred a couple of fingers? -lose a hand? -lose an arm? -die?
