tannerite.com youtube.com/watch?v=VRTQmf99RIs Somebody told me about this stuff today, and it looks pretty sweet. Binary explosive, so standard shipping is legal and easy. It seems that in order to detonate you have to hit it with a minimum velocity, but I haven't found any hard numbers on that yet. I was able to find accounts of people doing impact tests on the mixed product with sledge hammers and nothing happening, so it seems pretty safe. Also found a bunch of vids on youtube for it. Anybody here ever used it?
