Explosions take the path of least resistance. They shoot in sequence to
provide that path. First sequence starts it. Second will blast the rock
to where the first was, and so on, and so on. It's more controlled and
you use less powder.

I think you misunderstand. These were half ton charges many feet
apart. Turned hundreds of acres into rubble. I don't know but I will
bet the endloaders and trucks are really big. The ships certainly are,
thousand footers that are too big to get out of the Lakes.

Come to my place for the 4th! Illegal (in CA), and VERY good.
Shhhhhhh....

Heh - I just came back from SC - I got some stuff that...well, let's
just say it's in the artillery class. :)

My county will arrest you if they catch you with sparklers.

Pansies. Sparklers?

Unbelievable. Hell, when I was a kid, we used to chuck 1/8 sticks of
dynamite around like fire crackers - nobody ever got hurt. Maybe we
were just smarter than the average kid now days. :)

Had a friend who's dad was a pyrotechnics guy as a hobby! He'd make us
some cool stuff! Made me a small bomb once, and I chucked it in my
uncle's old cast steel concrete mixer! The end result was lots of
pieces of the barrel all over the place, and an ass kicking that I
received!

Ever see that episode of Mythbusters where they loaded up a cement
truck with 3 tons of HMX?

There was nothing, and I mean nothing, left of that truck. :)

Yes, I did! I've told my wife I'd move back to the S.F. bay area if I
could get a job with the Mythbusters!



Last week, they did a thing about making diamonds and went to the
University of New Mexico School of Mining Engineering - did something
similar with RDX - about 1500 lbs of the stuff in a tall tube.

The shock wave was simply amazing.

One of my favorite TV shows - 'splosions galore!!- Hide quoted text -

Yep, explosions and lots of other ways to ruin perfectly good stuff!

My welding instructor dislikes mythbusters. *Bad welding practices. *The
lady with the Tat's that welds at times use to work for the instructor, and
was not high on *his list of quality. *But it is a fun show to watch.- Hide quoted text -

And I recently seen where people are saying that Jamie (the mustached
guy) is an asshole to work for! Oh, and I had a chance to look at the
Venza up close, that's a pretty cool vehicle!

If you can come up with potassium chlorate you can make some pretty
nasty stuff just using 40% sugar and a dash of potassium chromate.
It is probably hard to buy these days without getting a call from ATF
but it used to be available at Fischer Scientific if you could come up
with a plausible story.

That's what's nice about living in the country and knowing a lot of
farmers.


Yep, when I lived in western NY, we had all sorts of homemade fun!
