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.

       Well, provided you happen to be carrying one of these when you get lost at sea...

pertinax, Nov 20 2006
  

       Oh, a gun for *deterring* sharks... I thought it was a gun that actually fired live sharks out of it at high velocity.

theleopard, Nov 20 2006
  

       theleopard, - ah, sort of the aquatic equivalent of an elephant gun?

Ian Tindale, Nov 20 2006
  

       //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//   

       Um... a large prick leaving the shark alive will leave a blood trail all the way back to you, as the shark swims away. More sharks will pick up the scent of blood and follow it back to you, after they deal with the bleeding shark, perhaps.

21 Quest, Nov 20 2006
  

       //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.   

       Unwieldly.

theleopard, Nov 20 2006
  

       I remember when I went on safari with a staple gun. Won't be making that mistake again.

Ian Tindale, Nov 20 2006
  

       Did it fire bread, pasta and rice?

theleopard, Nov 20 2006
  

       Would make sense, theleopard. Fire bait from the staple gun to lure the target into range, then line up the shot and fire the hungry shark at the elephant. What an epic battle!

21 Quest, Nov 20 2006
  

       I'm on the side of the shark. -

DrCurry, Nov 20 2006
  

       What do we shoot the elephant at?

theleopard, Nov 20 2006
  

       I was really hoping that this would be some form of gun that fired out sharks...

Jinbish, Nov 20 2006
  

       Mice, of course.

21 Quest, Nov 20 2006
  

       //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?

Shz, Nov 20 2006
  

       Jinbish's Shark Gun would take care of food.   

       pesky water!

daseva, Nov 20 2006
  

       //I was really hoping that this would be some form of gun that fired out sharks...//   

       That's what I said...

theleopard, Nov 20 2006
  

       //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.

Jinbish, Nov 20 2006
  

       Face the awe-inspiring power of my Bengal tiger gun!

21 Quest, Nov 20 2006
  

       So, hang on, what does an anti-aircraft gun fire out?

Ian Tindale, Nov 20 2006
  

       DC-10's?

Shz, Nov 20 2006
  

       Little old ladies?

Jinbish, Nov 20 2006
  

       C-5's? (C-5 is second largest plane in the world, the biggest is some Russian plane)

21 Quest, Nov 20 2006
  

       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.

twitch, Nov 20 2006
  

       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.

Jinbish, Nov 20 2006
  

       That is very true, Jinbish. Dolphins have been known to bludgeon a shark in the gills with their blunt noses to devastating effect. 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.

21 Quest, Nov 20 2006
  

       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.

twitch, Nov 20 2006
  

       //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.

Jinbish, Nov 20 2006
  

       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?

Shz, Nov 20 2006
  

       Why not just have a gun that fires a capsule with chum and blood in it.

Chefboyrbored, Nov 20 2006
  

       //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?

Trickytracks, Nov 20 2006
  

       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..

twitch, Nov 20 2006
  

       //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.

imaginality, Nov 20 2006
  

       //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!

gnomethang, Nov 20 2006
  

       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."

daseva, Nov 20 2006
  

       No worries! Hey, it's everyone's Shark Gun now. But we have to take turns using it.

theleopard, Nov 21 2006
  

       //have to take turns using it// Except the sharks, the gun might be too sharp for their little fins.

zen_tom, Nov 21 2006
  

       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?!

theleopard, Nov 21 2006
  

       The sharks don't have guns (due to the aforementioned fin issue), just frickin' laser beams.

zen_tom, Nov 21 2006
  

       Curses! [z_t] beat me to it!   

       Throw me a frickin' bone here!

Jinbish, Nov 21 2006
  

       I'll take on your Laser Sharks with my military trained Toxic Dart Gun Dolphins!
