Which Explosive is the Most Illegal -Explosives Lore-

This is useful in a sense, that just because I am interested in these subjects as much as I am with almost everything else....

People can assume that all sorts of things are good ideas, without knowing enough or all about the subject, and while in a professional sense,I would love to do a whole chemistry course on creating and manufacturing explosives, with all the training, all the right equipment, all the right materials and all the right safety gear etc.,

Aside from pure curiosity - like how to impact weld copper plate to stainless steel plate, to make cladding etc... which I don't have any need for....

If you get the things you do need done, wrong - for the most part it's highly survivable - generally speaking, and with explosives - get that wrong, it's over in an instant.....

I would like to use shit loads of explosives in tunneling through a mountain though...

Sort of like Brunell's railway tunnels.. or for road ways etc..

AND the video is a good illustriant of why - even inadvertenly, mixing up different chemicals etc., can produce all sorts of unforseen and unexpected results...

Mixing up house hold cleaning chemicals - beyond bar soap and dish washing liquid, on the same sponge - it's just a dumb idea.
