There may be easier to fabricate explosives - just search the net for the anarchists cookbook. I think that I remember that you can fabricate something equivalent to plastic explosives from household chemicals and spark it from something like the piezo element from a lighter.
Doesn't seem like something that I would want riding losely or tightly packed in my pocket survival kit though. Reminds me of
this post .
where you will find this interesting piece of info
I'll use this opportunity to speak on lighters since it was brought up. This opinion is common among weldors but probably doesnt really apply to everyone else. Butane lighters of any variety and welding machines (or cutting torches) are a bad combination. Steel melts at 2850 degrees F. Imagine what happens to any butane lighter when a ball of molten steel hits it. Most people carry lighters next to their heart or in a front pocket. I really dont want any explosions in either location. I'm not sure which would be worse <img src="images/graemlins/smile.gif" alt="" /> This is why you see so many construction workers with zippo lighters instead of cheap plastic butane lighters.
