Does Tedd see something fishy?

Commentary

It's time... For SCIENCE!

Or possibly dorks talking about super hero powers.

Misnomer

This one time, at Mythbusters camp, they were testing whether you could bulletproof a car with phone books, and they kept escalating the firepower, and it’s like, no, nothing is bulletproof, except maybe deep water, and you have to establish a range in which the myth can be confirmed, because otherwise you’ll inevitably get to a big enough gun, and then “busted” becomes the default outcome, AND I LEARNED THAT FROM WATCHING YOU, MYTHBUSTERS, I LEARNED THAT FROM WATCHING YOU

(Turns out water doesn’t compress and will totally mess up bullets, so it’s for all intents and purposes bulletproof past a few feet, but even then you could probably build some sort of bullet projection device that could get through a given body of water, though that would potentially require a system so unwieldy as to be impossible to construct with earthly materials within atmosphere, and might require extraterrestrial assistance in order to be constructed.)

(That’s just layperson speculation, though. I am not an engineer or an extraterrestrial.)

You've got teleporting magic (Susan's fairy dolls appear from storage without crossing the intervening distance); "bullet proof" works fine if it teleports the bullet just before it contacts the superhero. You can teleport it back going the other way (with adjusted energy; the usual Superman thing, looks like a low-energy ricochet), teleport it into space, teleport it past the superhero (bullet-transparent; bad for bystanders...), teleport it into the dirt, the bad guy, or over the "this week's bullets, please recycle" bin at Superhero HQ.

Did you know that the costume has to be at least as resilient as the wearer in order to *not* be torn to shreds in the course of a super fight? Or a physical super fight, at least. Not saying anything about Doctor Strange's outfit.

And of course, if you give the bullet enough kinetic energy, compressing the air itself begins to be a problem...

I remember that myth and I remember that it came from an episode of Burn Notice. Thing is; Mythbusters did end up confirming (or at least proving as plausible) the version that was in said episode. The protagonists only needed the car (actually a big four-wheel drive or whatever you Yanks call them) to be resistant to pistol-grade ammo - I think the biggest thing fired at it was a MAC-10 which is chambered for .45 rounds. The tires were filled with some sort of sealant (can't remember much beyond that) so that they wouldn't deflate if they took a round, and they still had to spring for bullet-resistant glass/polymer/whatever for the windows. And, even then, the phone books were only enough when paired with the car's metal exterior.

It was so obviously inspired by that episode, and yet they didn't define the parameters based on it. They were just like "is it bulletproof? Let's shoot 50 caliber bullets at it! Nope! Myth busted!" It's one of the rare episodes I will just RANT about.

In World War II, the Imperial Japanese Navy used armor piercing shells in ships mounting 14" or larger guns specifically designed to hit water first and either impact below the waterline or explode beneath the ship. (Armor piercing shells use delay fuses to give them the time to kinetically penetrate before exploding). Note that AP rounds of the time were encased in metal as hard as the face hardened armor the warships used. Modern AP rounds use other methods. Finally, for underwater attacks modern torpedoes are designed to go under the ship and explode beneath it, as the incompressability of water creates an effectively upward oriented shaped charge. During WW2 these had been developed but the detonators were very unreliable.

Reminds me of one of the earlier Grrl Power comics: https://grrlpowercomic.com/archives/comic/grrl-power-318-now-she-looks-human/

I'm reminded on an episode of DS9 where there's a rifle that was made that was based on your run of the mill projectile rifle, but made to be able to bypass forcefields by catching the bullet as it exited the barrel in an teleportation beam, and making it materialize a set distance away AND it somehow managed to keep it's momentum in order to continue to it's target.

So, I have an engineering background, but I haven't actually sat down and thought about hydrodynamics and done research on bullets and everything, so this is effectively a layperson saying the following: Spear guns do work under water (though probably not as effectively as in the movies). Torpedoes also work under water. IIrc, when the Mythbusters were testing whether water was bulletproof, the more energy the ammo had, the sooner the ammo stopped or broke apart. As such, it seems like you want a relatively slow moving, heavy, and hydrodynamic projectile (like a spear) and you might need to give it a propulsion system if you want it to go any appreciable distance (like a torpedo). So, yeah, by that point it's hard to really call what you're shooting "bullets" anymore, but...

KINETIC ENERGYYYYYY!

I came here to say the same thing as you. I haven't done the calculation either (sorry ^^'), but yes, according to the myth, something moving slowly enough will not break when entering the water. Which make sense, since at low speed, water has the time to get out of the way, and the object can travel through it (though loosing energy, since it has to push the water). In order to compensate for that and keep enough speed and penetration power, you'll want something heavy, pointy and hydrodynamic, and... you end up with a harpoon =).

Other thing about water, it will flow and cover whatever hole that was shot into it. So you cannot weaken it like you can other armour by shooting more holes in it.

Actually, shells designed to hit the water first and then penetrate the (presumably) thinner armor below the waterline go back at least to the late Nineteenth Century. Of course, they might still have to go through the torpedo bulges. (The battle between armor and armor penetration goes back at least to the first hominin who deliberately designed a spear or arrow tip to penetrate some animal's tough hide.)

Of course, women have a problem unique to them even when bullet proof. Probably NSFW: http://3.bp.blogspot.com/-NcCGcubFaTA/VSCJdb4ejiI/AAAAAAAADdc/gENpwpNJIUE/s1600/Bullet_Bounce.jpg

"Not an engineer or an extraterrestrial" OR ARE YOU??

John Trauger

I dunno...I think there's something fishy about this storyline....

John Trauger

Never being entirely bulletproff is ones first lessing playing superhero RPGs....

Yes. Bullets will bounce off him, but he'll dodge a gun thrown at him. :)

Gun guy here. As long as something can stop a .950 JDJ, it's truly bulletproof. Anything larger would be an artillery shell.

It depends on the size and speed of the bullet. My own idea of a fast enough bullet to go through water is a sufficiently massive Near Earth Object nudged into the Earth’s gravity well. Once it reaches 11 kilometers per second it will go through water no problem. And will release energy enough to make your average fission device hide its warhead in shame. As the Mythbusters say, you just need a big and fast enough bullet.

Is he facing a Black Manta knockoff?
