Using Explosives
Last weekend during one of my tests I let a guy "blow up" a dead tree. He merely wedged it between some loose bark and lit the fuse. It removed a little wood and blew the surrounding bark off. We put another one in a hole in the tree apparently made by birds and wood eating insects, it splintered the tree very well and bowed over.
This makes me wonder. More importantly probably than being able to make explosives is knowing how to use them. The post about lifting and tearing a car apart does too.
DuPont used to offer a book called, "The Blaster's Handbook" I believe was the title. Many large libraries still carry copies of it. It is very detailed in demolitions using explosives. From loosening soil to imploding small structures and everything between it is a great book to have read.
Explosives can and will do a major amount of work, but the blaster has to start it. This may be as simple as tamping the explosives to direct force or laborous as cutting roots, support trusses, walls, and beams.
As a start picture how you want the item to be demolished to look like after the blast. Where you want it to end up. Compare that to where it is still standing or laying. You have to direct the force of explosives to "desupport" the structure in such a way that it will fall under good old gravity to that spot. Explosives just provide the big final precise kick to get it under way. Before they can be employed the blaster has to make all the little nudges and line it all up. This may mean milisecond to seconds away sequential detonations, which is very hard to do without blasting machines, det chord, electronic detonation, delay, and splicing equipment. Good explosives must be used as well, a misfire really sucks. You could be left with an, on the verge of falling, yet still standing building that could fall any directions. Do you want to go replace the explosive(s) that failed or redesign the shot?

Re: Using Explosives
Like when they implode a house they have to put the explosives in certain places or it wont work.

Re: Using Explosives
It was a valid response. When demolitions experts need to tear down a building, they implode it so shit doesnt fly everywhere, so yes they need to find certain spots to put the explosives so it won't tip over and knock out other stuff. What Real meant I think was the correct placement of explosives for maximum explosion, not correct implosion, like EXPLOSIVE805 is referring to

Re: Using Explosives
Oh, and if you had to clean up cat shit in your yard everyday, pick up trash that cats knocked over and scatered everywhere, and get attacked by one when you try to take out the trash, you probably wouldnt like them either. Besides there are too many of them around where I live.

Re: Using Explosives
I don't like cats either.
But it does go for imploding as well as anyother type of blasting. Imploding being the safest is also the hardest.

For fucks sake, it's just meat. I'd eat human if it weren't illegal and bothersome.

Re: Using Explosives
I bet people taste like shit, with all the crap and chemicals we eat, I best we taste synthetic. I'd eat a cat before a human and a snake before a cat.
There is a difference between not liking something and having a passionate hatred toward it. Not liking=ignoring, Passionate Hatred=going around and shooting it with poison darts et al.

Re: Using Explosives
I can see eating cat or snake or even human if you were stranded and there was nothing else to eat but why would you if there was other food like steak.

Re: Using Explosives
Curiosity and some people do enjoy the flavor of snake and probably wonder why we would eat a cow if a snake was around. Don't get me wrong I love steak, nothing better than bloody meat. If I could choose what causes my death, it would have to be trichonosis.

Re: Using Explosives
Apparantly snake is great eatin. I was watching the propaganda machine, they had a show where some lady was giving out free samples of mystery meat (snake), people were raving about how great it was, and asking where they could get some. "It's snake" "AAAAHHH! OH MY GOD, IT'S AWFUL, IT'S AWFUL, IT TASTES LIKE CRAP! AAHH HAH AHA spit spit ptooey."

Re: Using Explosives
re: eating humans.
Some years back, in an old book, I read an interview with a former cannibal from Borneo,( he had since become a christian). He claimed that whites and blacks were not very tasty, that the meat was too rank. On the other hand, he claimed Chinese were very good eating, and that they tasted like chicken.
Presumably the difference in taste is due to diet, as blacks and whites tend to eat a lot of meat, while Orientals , at least in Asia, tend to eat relatively little meat.
I have no idea what Orientals raised in North America would taste like, but I suspect they would be as rank as whites and blacks.
