i want to post some vids of explosions n stuff on youtube but i am worried about getting my account shutdown. How do I avoid getting shut down, in other words what should i or should i not post on youtube.

There are 1000s of vids of people blowing shit up on youtube. If your that worried jsut set up another account. Although I have never understood why people would want to put vids on youtube in the first place?

Its an e-penis extension. As well as sharing experiences with other e-people. Kinda like real people have videos of birthdays and accomplishments posted on facebook. We the 'underground' blow shit up on film.

HA! I love those contradictions - great phrasing.

Heh, 800 grams of flash powder out in the desert. Just outside of Sun City, CA.

The explosion tossed about 50Lb or wood straight into the air so fast you can't see it by the camera...

That was pretty shitty. But pretty much all explosions are neat to watch. Did you put it in a fire and wait for it to go of, or did it have a fuse?

Actually, you're seeing that from a few hundred feet away. The charge was behind about 5 - 6 feet of earth. The electronic ignition failed so that was a last ditch attempt at destruction from a distance.

You can see the shockwave shook the mounted camera inside the vehicle.

I'm glad I wasn't only 20 - 30 feet away on the other side of the hill from that device as originally planned. The shockwave from the original, stout device may have damaged me internally.

Why waste so much flash power?
There are allot more explosives that use a 1/4 of what you did and produce a explosion double the size of that.

There are very few youtube explosions that I thought where worth watching, and most of them are "flour bombs". Interesting stuff - though nobody on there has a video of the proper way to ignite a dust explosive.

One of my favorites
YouTube - Exploding Flour

The whole exploding flour thing is very neat. I just tried it and it actually worked. Was not nearly as impressive as the video, but it was pretty cool.

Here's the amazing thing, the video is only showing about half of what a five pound sack of flour is capable of. Properly rigged with a dust initiator, a five pound bag of flour can be used as a demolition munition to collapse a 10x10 space.

Well, because it was there, needed to be gotten rid of & there were no other reagents to work with. And, FYI, you can't exactly see or feel the shock wave that thing produced in that video. Besides, as I stated, it threw about 50 pounds of wood straight up in the air, faster than the cam could capture. Also, that's from behind several feet of earth... Now, with that 800 grams gone, there's only about 3 or 4 times that to be dealt with left over...

The vid is poor, I'll grant you that, so I can understand your lack of grasping the significance of the detonation...

needzhelp · #13 (**permalink**) 09-13-2009, 10:27 PM

i tried to make one but failed. and the flour bomb tread didnt help much. How can i make me one of those? I've got a few firecrackers to put the flour in the air.

I've done something similar with liquid fuels, never tried with solid powders but it shouldn't be significantly different.

You'll need to make a high explosive burster and a surround of fuel, in this case your flour. Make sure to use a brisant high explosive so you get a fine fuel dispersion. Generally you'll want between 1:100 and 1:250 parts burster to fuel (so for 250 grams of flour, you'd have between 1 and 2.5 grams of high explosive as your burster charge).

Next you'll need a high explosive initiating charge and a timing circuit.
Once the burster charge disperses the fuel into a fine mist in the air, your initiating charge will detonate, sending a shockwave through the fuel cloud and causing a mixed detonation/deflagration. In general you'll never get a 100% detonation of anything but maybe ethylene oxide.

The timing delay will vary from fuel to fuel, based upon the amount of oxygen it will require and how well dispersed it is.

For most liquid fuels tested on a small scale, the delay between burster and initiator should be between 60 and 90 milliseconds.

Determining the correct delay for a given fuel, burster size, etc can only be determined through testing.

Of course, for flour it's probably not going to detonate very much no matter how good your timing and initiator is, so you might be just as well off dispersing your flour near a fire...

For fun I recently did a dispersion test of 5 gallons of gasoline 20 feet from a fire... Pretty impressive fireball, 90% of it was gone in much less than a second.

Well, you could do all of that, or you could use the dust ignitor design from TM 31-210 - made from a tuna can, a castable or plastique explosive, and a few strips of aluminum foil.

Is that a two stage device? Without first dispersing, then initiating a fuel cloud you'll have a far slower combustion or detonation, and therefore much less destructive power.

I've got a video I made on the subject.

No, it's a single stage - it may lack the power of a true Fuel Air Explosive, but on the up-side, it can take out 2,000 cubic feet and fits in a shoebox.

Sounds good, there's much to be said for simple practical devices that work!

Got any links on the design of said device? I wouldn't mind filming something like that with my high-speed :P

The design and construction is laid out in the previously mentioned TM 31-210 booklet.

EDIT: My apologies, I confused talking about the book in another thread with this one. You can find a copy of TM 31-210 on scribd.com
