I used to make that strange sound from a homemade mortar all the time. It was 100% repeatable. I think it's a vortex ring. Mine was much smaller, but can be re-created reliably. Just bury a 55-gallon barrel & put stuff in it. Not too much, or the effect is swamped. There were no canyon walls near my location and I heard the same kind of warbling whistle. I believe the sound source wanders in the same way that a dust devil will wobble around in the air.
Did you shape the explosive in some way.? Or compact it, or do both or... whatever.? The smokering didn't seem to turn THAT fast, in the vid.?! Never heard that noise, Surely not in connection with a Deto... Confusing, but, I'm gonna check the net for answers.!
A hail cannon now that makes sense, basically the smoke ring is spinning at such a high velocity, that it creates a low pressure area inside the ring causing it to suck in air rapidly, thus acting as a giant whistle.
You must have been in a canyon. As someone correctly pointed out, it is the vortex doing this with it being closely focused. The walls of the canyon would amplify the sound considerably. I have heard more of less the same sound from landing jets in an area where the runways were surrounded by tall trees. Standing near the approach path will create the same weirdness of sound.
yes, the sound is generated from vortex ring, the itself sound I had listen when I went at runway landing aircraft, after 30 second that the plane was arrived...
...listen it from true would be fantastic !!!
if you don't have new ideas about new test, I suggest a thermobaric ring, we are in theme :-)
well it might be super high turbulence, since an explosion gives a really tence air movement for a short second too, and maybe that turbulent stream of that explosion lets it spin really fast with a weird sound O.o i got no other clue to explain this either :x
@darkorderofmagi J7 is just a nickname I gave to one of my bullet sensitive ammonal mixures; ETN is erythritol tetranitrate, a sensitive secondary HE that is made by nitrating erythritol (a sugar alchohol).
insane effect indeed, its usually sound rubbing into eachothers wave forming a small tornade making the sound get squeezed out into the most amazing forms. or you pistoff an alien hovering in stealth xD
That was Frigging AMAZING!!!!! That would be sweet if you could catch the vortex on camera! That must have been spinning incredibly fast!! It would be cool to see the vortex through a thermal imaging camera! Nice job that was sweet!
lol pretty weird, ive heard weird sounds when setting off ETN, like the boom being followed by a sharp squeaking sound, but nothing like this, i think you might have opened up a worm hole or somthing:)
What the hell!? That was such a weird sound, I really wish you good luck in reproducing it! Would be awesome if you were able to, and film the smoke ring while it flew up next time :D
@HolyDeltaWings 7 lbs of an ammonal mix at the bottom of a 1.5 feet deep hole. Had a rolled up paper tube full of the charge, leading to the main charge. Wish I could see it at 50,000 or 100,000 fps; it would tell an interesting story.

It was actually pretty loud; at first the detonation covered it up for a couple seconds, but then we could hear it as clear as a bell.

You think there would be more accounts of this if it was simply super-intense turbulence. So strangeO_O
