Okay, I was prepared to HATEā„¢ this video because of its use of the all-too-overused O Fortuna, but then the cannon shots were synched up perfectly with the music, and I fell in love with it all.

We built cannons in shop class at school. The instructor had this uncanny ability to recite the same speeches verbatim every semester - I was a TA for him, so I got to hear them quite a lot.

"These cannons, as designed, cannot fire. However, if you drill a 1/16" hole in the barrel before tapering it, it can be used as a small firing hole. I didn't tell you this, but use no more than 2 grains of FF grade black powder, and the barrel is conveniently sized to accept a small piece of chalk as a projectile. The upside to using chalk is that, if it gets caught on a burr, the chalk will explode instead of the cannon barrel.

"If you get caught, I will disavow all knowledge of your actions."

Nobody uses the 1812 overture any more?

Also, how dangerous would this be if you hit someone with it?

I think I'd want to line up a bunch of them on the side of a model ship.

This looks like it could kill somebody.

Hot damn! Nerd out with numbers! (MWAAhaahaa)

The US Army generally assumes that a projectile must deliver 60 foot-pounds of energy to produce a disabling wound. (That doesn't mean kill, please note.)

That's 81.6 joules.

Kinetic energy == (m * v^2)/2

So V = ((2*E)/m)^0.5

E is 81.6
Assuming a 0.25 gram (0.00025 kg) BB, then we get a velocity of 808 m/s. That turns out to be 2.4 times the speed of sound (340 m/s). I don't think this cannon can do that.

What amazes me about that thing is how consistent it is. Shot placement is nearly identical on the three shots against the computer monitor. They must be using a lab scale to measure their powder charges.

I think this could kill somebody much more effectively then a BB gun could. I'd guess it's comparable to a .22. The projectile is round, so it wouldn't penetrate as well as a bullet, but I don't think you'd need (for instance) to get hit in the eye with this thing to be in trouble.

As above, this is a firearm. Neat engineering and all, but not a toy.

That was my thought at first too but then it quickly became wonderfully superridiculous. This is probably the best use of O Fortuna in at least a decade.

On the basis of nothing but the seat of my pants, I'm skeptical that anything with such a short barrel could be consistently aimed with that degree of accuracy. I started to wonder after the 3 tightly-grouped shots on the monitor, and full skepticism kicked in about the time he started shooting things hanging in the doorway on the other side of the room.

And the insistent "no tricks were used" disclaimer did absolutely nothing to quell my suspicions....

If you have arcane knowledge of projectile accuracy involving the seat of your pants, I don't think we want to know about it.

Greg_Ace : And the insistent "no tricks were used" disclaimer did absolutely nothing to quell my suspicions....

Would shooting a hundred times and only posting the ones that successfully hit be considered a trick? Because that's how I would do it. It did actually make the shot, you just didn't need to see the 99 times it didn't.

Nobody uses the 1812 overture any more?

This is the sort of thing that For Those About To Rock was made for.

The canon has degree marks on the side. Obviously half the fun is determining trajectory and lining up shots (and showing off on YouTube when you nail it dead on). It's like the classic video game Scortched Earth, version of the "artillery game".

I'd have thought that too, but apparently we are wrong.

Note the monitor? All three shots hit the exact same point. Even immediately prior to the third shot there are no "misses" visible on the screen. Even if there were some misses (probably a lot of those distance shots), this thing is pretty consistently accurate.

(Dear Accuracy vs. Precision pedants: yes, I know "consistently accurate" is technically redundant. Fuck off.)

Need to watch this video later -- on a 22K dialup from home. (Yes, some of us still use copper for the internet).

I used to collect toy(?) cannons. Some of the early black powder toys(?) were pretty impressive.

Kids used to have much more fun.
posted by jgaiser at 6:19 PM on August 6, 2010


Ryvar and quin, the two of you pretty much define the points of my dilemma. If they're cherry-picking only the best dead-on shots for the video, why do we only see three hits on the monitor? Yet if it isn't faked or edited, how the hell did he get that damn thing aimed so "consistently accurately"? Especially when we can see the recoil movement, so it's not like he's got the thing locked down in perfect position.

I claim no expertise, and I'm quite willing to be convinced it's legit...which would make me even more damn impressed.

and hippybear, I'd favorite your response more than once if I could, just for the out-loud laugh I got from it

posted by Slithy_Tove at 7:14 PM on August 6, 2010


I'd make a guess that the base can probably be locked down pretty tight, and it's small enough that any recoil based forced would lift the entire cannon without necessarily shifting the relationship between the barrel and its base which would mean that re-aiming it at a fairly close target would be as simple as having a mark on the table that he could consistently place it on.

Or, and I'm fully willing to concede this as a possibility, maybe the guy just shoots the thing enough that he has gotten really good at judging it. Maybe each one of these is a first shot hit. It's not impossible, just a little less likely than the alternative.
posted by quin at 7:24 PM on August 6, 2010


I'm thinking that with the monitor shot, what's to miss? It's only four feet or so. The elevation of the piece is set, you can pretty easily eyeball to within an inch of the same distance, there's not much to line up in terms of direction...

Looking again, he's lining the gun up on a sheet of what looks like lucite, right at the front edge of the sheet, so his range is fixed. (The gun moves but the sheet doesn't) And he's got a rudimentary sight.

The version of Scorched Earth I played way back in about 1992 or 1993 was pretty simple and loads of fun. I think this is it here.
