I wanna blow something up

yet in your avatar your a 'Drunken fool(usually)'

It's fun being an oxymoron.

Wow.

The quality of threads on AO has gone down so much, along with the IQ of some of it's members.

Oh well - social darwinism will get to work here soon enough...

I'm just going to assume you really don't have a clue what 'Social' Darwinism is.

Also, as you get older & look back, you realize just how many 'Oh ****!' & 'I should be dead' moments you have. When you realize this, you usually slow down a bit when it comes to doing blatantly stupid & idiotic things and you tend to weigh the consequences & risks of your actions. You know.....responsibility.

OK:

#1) Perchlorates in crystal form are VERY unstable. Please do not blow yourselves up, its not as much fun as it sounds. If I were you two proto-chemists, I would edit my posts to remove that info. No sense getting anyone killed, and/or getting arrested.

#2) Don't blow up anything with glass in it. Its a ***** to clean up, and the shrapnel sucks. Same goes for thin sheet metal and hard plastics. I suggest fruits and vegetables (pumpkins rule), or whole chickens (dead preferably). They are most interesting to destroy, but produce no real bad shrapnel, AND are biodegradable.


How do I know these things you ask?

I am about 16 hrs away from graduating with a degree in Mining Engineering, which was just my vehicle to get my minor in Explosives Engineering.

Let me rummage for a bit, and I'll see if I have any vids that aren't too big to post.

Explosives

EDIT FOR MOVIES: (Right Click the Links and select "Save Target As")

This is what shots are supposed to look like (you know, when we do our jobs right).

Quarry Shot - 1.5 Megs

Surface Lift Over Coal Seam - 1.1 Megs

Trenching Shot & French Drain Shot - 1.7 Megs

Breaking a Boulder - 5.5 Megs

Couple of High Speed Vids. The first is of a stemming ejection. Note the fountain of rock that shoots out of the top of the hole. This is wrong. The second is what a good hole shoots like. No failures, good breakage.

High Speed Vid of a Stemming Ejection (confinement failure) - 3.3 Megs

High Speed Vid of What the above should have looked like. - 3.8 Megs

Now a few screw ups.

Here is a compilation of various shots that produced a lot of fly rock. This is obviously bad. This is the main problem we try to avoid.

Fly Rock Examples - 1.6 Megs

Here is a hard core shot of some big fly rock. This illustrates perfectly why we strive to prevent it.

Fly Rock - 3.7 Megs

This is quite possibly the worst pooch screwing I have ever seen. Let me toss out some measurements to give you a sense of scale for this shot. The face height (the little step that makes the shelf) is ~90 feet. Its over 1000 feet long, and over 300 feet wide. Compare the face height (the little shelf) of 90 feet to how high up in the air most of that fly rock goes. Also of note is how much ground vibration is created. The camera is nearly knocked over. This is basically exactly the opposite of how you are supposed to do it.

Big Bad Quarry Shot - 8.5 Megs

Mining Engineering?

I thought you were working on your degree in APS (Aftermarket Paintball Stuff)

Mining Engineering?

Well, its funny you should mention that. If I were to choose, I believe that I am only two or three classes from a manufacturing minor as well.

But, since that would put me off another year from graduating (and man have I been there too long already), so its a non-starter.

My buddy took a class in CNC machining, which turned out to be totally worthless. We both actually knew more about it (having taught our selves) than he got from the class. I got a good chuckle out of his final project (using canned cycles to drill several holes and then a tool change to contour the outside of a very simple part), and he got to waste a grand.

We also blew away his senior design team's competition with a nice CNC machined prototype that functioned like it was supposed to. Everyone else showed up with duct taped cardboard and CAD drawings.

I may not end up with a degree in mechanical engineering, but I can hold my own just the same, be it machine design, manufacturing design, structural design, or just cool PB stuff design.

The only two major classes I'm missing from the Mechanical degree line is the two Thermo Dynamics classes (which are always full, and a real PITA once you get in). The information you glean is really only good for thermal energy exchange systems anyway (steam plants, internal combustion engines, cooling loops, etc). As long as I don't try to build a nuclear power station, I should be OK for now.

Mechanical bits have always been my thing anyway. Mining combines all the things I love: Explosions, Big Machinery, Scenery that Changes, difficult and unpredictable problems, and good money when you're done. Its a good net to fall back on, you know, just in case I can't make my millions in Paintball.

I remember one time I described how a pressure(works/drano/etc) bomb works once, not how to make one but how it works, and it got edited. How this thread has lasted this long, I don't know.

And DO NOT, I repeat, DO NOT mess with Acetone Peroxide like someone suggested. You will die unless you are very experianced. Just because it's fairly simple does NOT mean that it won't blow your face off 6 times before you hit the ground in many tiny peices.

This isn't mine, but here's a vid of a can of Starter Fluid exploding.

Exactly.

Nitroglycerin is not hard to make.

It is, however, hard to make and not die while doing it.

Dynamite wiped out the use of straight NG for a very good reason = the stuff is nuts to handle or work with, and that's when its cooked correctly. Unstable mixes/forms (be it NG, chlorates, perchlorates, TNP, TNT, or whatever) often kill even the most experienced handlers. Novices have zero (0) chance of making it through unscathed.

I will say it again -----> Chemist guys - Go edit your posts before someone does something dumb and gets croaked. OR, the thread dies and we don't get to see anymore BOOM movies.

NNNNOOOOOOOOOO!!!! I'm at work!
