Shark Gun
A spring-loaded device for deterring sharks | |
Spears and knives are used when chasing
off sharks but sometimes the shark's skin
is so tough that they do not have power or
impulse enough to penetrate.
This device was thunk when remembering
those finger pricking devices where they
pulled on a trigger which cocked the
spring and released
it, causing a needle to
shoot out and retract just as fast.
This device would be similar with some
differences: the needle would be a blade,
about 4-6 inches long. The spring would
be powerful enough to propel the blade
through tough shark skin.
Because of the strength of the spring, it
would have to be cocked separately from
the trigger action.
This is not meant to be a temporary
solution, like a boomstick (which are
brutal weapons, just a shotgun shell on a
stick that kills the shark). It is meant as a
lost-at-sea survival tool. Killing the shark
would lead to a lot more blood to attract
more sharks. A large pin prick would be
enough to chase the shark away while
being completely reusable.
Now you just have to find some food and
water.
(?) Like this?

Well, provided you happen to be carrying one of these when you get lost at sea... |
|
| |
Oh, a gun for *deterring* sharks... I thought it was a gun that actually fired live sharks out of it at high velocity. |
|
| |
//ah, sort of the aquatic equivalent of an elephant gun?// |
|
| |
Indeed [Ian], both of which tremendously ferocious weapons. Ammunition clips can be somewhat cumbersome however. |
|
| |
Did it fire bread, pasta and rice? |
|
| |
I'm on the side of the shark. - |
|
| |
What do we shoot the elephant at? |
|
| |
I was really hoping that this would be some form of gun that fired out sharks... |
|
| |
//the needle would be a blade, about 4-6 inches long.// //A large pin prick would be enough...// |
|
| |
A blade makes more than just a pin prick. Isn't this a stiletto? |
|
| |
Jinbish's Shark Gun would take care of food. |
|
| |
//I was really hoping that this would be some form of gun that fired out sharks...// |
|
| |
//That's what I said...// |
|
| |
Yep - I know. I just thought I'd express my hope for a better world. Based on guns that fire large carnivorous animals with big pointy teeth. |
|
| |
oh come on. Do elephant guns shoot
out elephants? |
|
| |
This gun need not be wieldy, maybe the
size of a regular gun, with a pump, that
is included in emergency rafts. |
|
| |
Why let the shark eat your friend when
you can eat your friend tomorrow? |
|
| |
[Shz], yes, the blade used would be, to
us, a laceration, but probably just a pin
prick to the shark. |
|
| |
The front end of a shark (the snout, rather than the gaping maw) is extremely sensitive. I suggest a blunt approach to this shark gun, rather than a sharp edge. The pin prick may cause some bleeding, which would be enough to be noticed by other sharks. |
|
| |
A boxing glove could be added for comedy effect, but I suggest that a rubber baton, the size of a can of soda be used rather than a needle-like approach. |
|
| |
Blunt trauma does make sense. I just
supposed that they would hunt down a
wounded shark like a pack of dingos. I'm
probably wrong. |
|
| |
//to punch it on the nose// |
|
| |
Ditto. But not with a naked hand. The shark's skin is rough enough to graze a human - causing bleeding and a potential metaphorical dinner-bell. |
|
| |
I shouldn't pick on the DC-10 anymore. Their service record has greatly improved. Besides, as everyone knows, anti-aircraft guns launch birds. |
|
| |
[twitch], how is this different than a stiletto? |
|
| |
Why not just have a gun that fires a capsule with chum and blood in it. |
|
| |
//Why not just have a gun that fires a capsule with chum and blood in it.// |
|
| |
Uhm. Well. Let's say the shark will think you're very sweet for providing it with a starter? |
|
| |
I just don't believe that a stiletto has the
power to puncture shark skin. and you
might be too tired to thrust and parry for
hours. |
|
| |
I wonder if a pepper/capsaicin concoction
released into the water would work, or just
attract more sharks.. |
|
| |
//I've heard the best thing to do when attacked by a shark is to punch it on the nose, though that may or may not be a myth.// |
|
| |
They tested a few shark myths on Mythbusters once, and that one did seem to work, especially when Jamie jabbed at the gills rather than the nose. |
|
| |
//So, hang on, what does an anti-aircraft gun fire out?
Ian Tindale, Nov 20 2006//
I don't know, but for goodness sakes don't fire it at an aircraft! |
|
| |
How foolish of me, [leopard]. Right, then, theleopard's shark gun.... I'm reminded of Animal Farm... Or, maybe just Animals... |
|
| |
"I've looked over Jordan, and I have seen
Things are not what they seem." |
|
| |
No worries! Hey, it's everyone's Shark Gun now. But we have to take turns using it. |
|
| |
//have to take turns using it// Except the sharks, the gun might be too sharp for their little fins. |
|
| |
Sharks with guns?! Are you mad?! You would take the most dangerous beast on the planet... and give it a gun?! Have you got some sort of apocalyptic deathwish?! |
|
| |
The sharks don't have guns (due to the aforementioned fin issue), just frickin' laser beams. |
|
| |
Curses! [z_t] beat me to it! |
|
| |
Throw me a frickin' bone here! |
|
| |
I'll take on your Laser Sharks with my military trained Toxic Dart Gun Dolphins! |
|
| |
[jumps in way too late, can't help elf anyhow] |
|

People put way too much emphasis on a shark's reaction to blood. As a spearfisher who has faced down many, many excited sharks - I can tell you that blood scent is very, very secondary to electro-thingamy they get from their ampule de lorenzi (spelt wrong, but y'know what I mean). Quite literally if you kill the excited fish, the sharks visibly relax. They remain inquisitive, as 1) they can smell the blood and 2) their eyesight and comprehension is good enough that they know that it's the fish that's dead and so they go for the dead fish, which just happens to be in your grasp. |
|
| |
Relevance - blunt/sharp doesn't matter. A trickle of blood out of a small puncture wound will not noticeably alter the behaviour of the sharks. (except for if you're around oceanic white tips. Those fuckers are batshit crazy and will straight up eat bits of you with no reason. They look so gracefull with those big B-52 wings but that's just to fool you while they work out which limb to rend first). Anyhoo, the trick is to give 'em a good thumping, do it once, do it hard. If you badger a shark with multiple jabs from a spear or knife odds on he'll get pissed and bite back. I'm not joking, little reefies will snap like a dog, then it's on like donkey kong. Ever had to juggle a half dozen or so 3-5' long reef sharks all a-jiggle with excitement because you just swapped red stuff with their mate? Learn from my mistakes. So the beauty of this idea is some spring loaded, wind-up whatever, pain machine. Like maybe 3 or 5 thin, sharp spikes that deploy 3" or so with a lot of force (it's hard to "hit" hard underwater, and you don't want to be making sudden moves around the sharkies, anyhow). |
|
| |
The point is, you don't want to hurt them. Sharks are seriously cool, I love freediving with 'em, sans spear, dead fish, etc. Just need a reliable way of giving them the hurry up. Electronic shark shields are not reliable enough to use as the sole defence. |
|
| |
They don't much care for being yelled at. |
|
| |
Wouldn't a sort of shark taser be more effective?
And no, I don't mean something that fires two
high-voltage sharks on the end of trailing wires. |
|
| |
What you need are two metal prongs which, when
pressed hard into something (eg, say, a shark)
press an internal switch to release a short high-
voltage pulse from the same circuit that powers
flash guns (maybe a bit beefier). |
|
| |
Seawater would only partially diminish the current
going through the shark, and in any case the
prongs could be insulated except at the tip to
reduce such current leakage. |
|
| |
I don't know how a shark reacts to couple of kV
being discharged through its snout. It's going to
make it either angry or scared. |
|
| |
I'd buy a gun that fired two sharks on wires. Granted the maintenance would be fierce, what with salt water tank chemistry and feeding, but imagine the reaction when you fired the damn thing. |
|
| |
I presume, then, that it's going to fire one shark
leftward and the other rightward? Otherwise the
recoil will be disheartening. |
|
| |
//I'd buy a gun that fired two sharks on wires//
|
|
| |
Would that be an over-and-under or a side-by-side ? |
|
| |
Maybe a single barrel with two revolving chambers. That way, after you invariably miss the guy with the first one, you can enjoy the look on his face as you draw a more careful bead with the second one. |
|
| |
ah, a repeater... perhaps a complicated method of moving the sharks + water into the barrels from a pool or something. I still think two barrels is the way to go though. I would think somebody barely missed by two sharks simultaneously isn't going to be in any condition to return fire anyways (cue giant octopus mortar). |
|
| |
Yeah, but can you imagine the press and the serious respect from the firearm community you'd get when you cleared a jam in that thing while engaged in witty repartee with your opponent? |
