    What is of interest here is how a flying sub could become hydrohobic if covered with this substance greatly improving a membrane surrounding the hull, effortlessly plying the currents with out friction. Could explain our Unidentified Submerged Objects ability to defy the known laws of physics but when taking to the air they must have a membrane of compressed air to float thru the air at one thousand times the speed of sound and reach speeds without drag. Once in outer space, there must be an envelope of some type surrounding the craft ?

      @Mojo Joji kinda depends on how we want to use ‘touch’. So, I never touch my food, but I swallow it and it becomes me. Yeah, I guess in one sense none of my atoms are technically touching each other, and the electrons don’t touch the nuclei, and quarks just wave at each other in passing. So touch becomes meaningless. And those who hunger for it are doomed to eternal sorrow. 😒🫳😞

    Holy damn. I’ve been imagining this exact experiment for a very long time, except with a superheated sphere utilizing the leidenfrost effect to surround the projectile with an air pocket. I’d love to see a race between the 3 types. I was pondering this a few years back as to how Russian torpedoes suddenly got so fast, the grainy video of it seemed to leave a trail of bubbles…
    Seemed a simple test, drop a superheated sphere into water next to a non heated sphere. Would love to see that

    Question: what's the amount of cavitation during the ball drop, measured in noise?

  • Jim Ciancio
    Jim Ciancio 2 months ago

    That's Great! Now that you're creating a cavitation space for your projectile without contacting the viscous fluid how do you control the direction of your projectile then if it's not able to grab anything around itself? With Hydroplanes we would ride on a cushion of air, but without having "turn fins" sticking down deep enough to bite the waters surface no matter what you did, you lost all abilities to steer the boat and are at the mercy of going the direction of the engines torque from the prop. So if you added some sort of turning fins which would pierce the surrounding air bubble, this will still be faster from drag reduction and still have the ability to control your directions.

    Interestingly something similar to ‘hydrophobic’ happens with the individual ash particles from volcano eruptions. So every minute ash particle is like a torpedo all gliding off each other.
    So the ash cloud can tumble down a mountain many times faster that standard dust would. Making volcanic ash clouds like high speed burning hot avalanches. So extremely dangerous and difficult to escape when one is heading towards you

    Once learned from a teacher, who was an ex-submarine technician, that the missiles do something similar. They blast air out of many areas around the outside of the missile, so that no water ever touches it. If water did touch it, it would create a lot of drag and the missile may spin out of control.

  • Blake Brown
    Blake Brown 2 months ago

    This is interesting. However, a torpedo has a prop on the back for propulsion. Cavitation like this looks like it'd really screw that up. I also wonder if this would create any issues with buoyancy as a torpedo travels horizontally, not vertically.

    Ive heard this is how penguins are able to launch themselves out of water: before entering the water they absorb (trap?) air into their feathers which helps to keep them warm underwater. As they reach the surface they release this trapped air and it reduces the friction on their body and they can accelerate to the surface

    • N Jones
      N Jones 2 months ago +1

      @Yosh Waters the issue isn't adhering the powder. It's keeping it on after shooting the bullet. Bullets deform when fired, maybe if you made a bullet completely out of this stuff but then it might be to fragile and break apart in the barrel

    • Yosh Waters
      Yosh Waters 2 months ago

      @N Jones I'm no physics expert, but could the powder not be adhered to ammunition? I can see how it might be impossible if the powder resists water by shifting and moving, because adhering it would prevent that, but as I said I'm no expert.

    I noticed something like this back when I was a competitive swimmer.
    Go completely underwater, and make your hand into a claw. Try to swing at the space in front of you as hard as you can, and your hand will go very slow, and it'll turn your body as a catches the water.
    Now try the same thing, except this time, give your hand some air. Put the back of your hand against your mouth, blow some air on it just as you swing. Your hand catches the air and it will envelop your hand. Your hand will rip through the water with a speed almost like you're on land.
    You can use air from the water surface too but it's all splashy and messy, and nowhere near as satisfying.

      Here's a few more variables.
      It was 25 yrs ago. This particular video sparked a memory. My uncle Gordon Connor of Halifax NS (maybe you can Google it idk) used to used vaseline when diving. As per other comments from divers that's a real thing. As for swimming with it.
      Its obvious you dont get it! My uncle was fucking with me as a young boy to get myself covered in vaseline at the lake while swimming as a joke and to force my mother his younger sister to wash every bit off because the sun would bake me like a Turkey.
      Maybe he really believes it makes you swim faster idk it's been a very long time . Maybe he just likes how it feels on the body. And like I mentioned in another comment, he has psoriasis so maybe it helped with that. With the chlorine and all.
      The water does feel a bit better while swimming with an oiled up body. Ie baby oil vaseline. Or for folks like you that spare KY jelly.

    Fun fact, in the special effects business we sometimes use lycopodium to make safe (or "safer") explosions, it is commonly also used to make fireballs etc. at concerts, Rammstein, for example, has a couple of such rigs and I've been lucky enough to get a chance to play around with one of them. The reason why we occasionally use this powder is that it makes a slower developing burst of fire than for example propane does, and it's safer to work with than flammable liquids as it won't ignite unless the fuel/air mixture is correct, plus it can't spill on the ground and set other things on fire. Normally we'll blow it through a pilot flame - when the ratio between lycopodium and oxygen is correct, it'll automatically ignite due to the pilot, and result in a rolling ball of fire going up. It resembles a gasoline explosion, minus the black smoke. The effect is called a fuel-air explosion, although it obviously doesn't create the pressure we see in the military application of the concept.

      @Cesar Coronel no, a hydrophobic surface on the vessel doesn't negate buoyancy it simply reduces drag. The seawater will still press against it and give it an upward force. *Edit:* for full clarity. The reason it makes the balls fall faster in video is that reduction of drag. But the balls don't drop because of the coating, they drop because they have a higher density than the water. Submarines are able to modify their average density by taking on or pumping out ballast in order to ascend or descend by changing the balance between the buoyant force and the Fg (force gravity) acting upon the vessel

I imagine someone falling through water the same way they'd fall if they jumped out of an airplaine. I can't fathom what that experience would even be like, tho im sure it ends in death one way or another.

    That sounds great, until you realize that the torpedo's screw needs to make contact with WATER, not a bubble of air.

    What would happen if you dropped a ball coated with the hydrophobic material in the ocean? Would the salt water/increasing pressure make a difference?

    If you were falling at high velocity impacting the water would kill you due to surface tension and water being non compressive. I wonder if hitting a surface like this would enable the drag forces to be dispersed enough to not cause damage to the person falling. Of course swimming back out might be an issue at that point... but lets solve one problem at a time lol

    What about super heating a metal projectile before dropping it in the water. Would it have a similar effect I wonder because the water that comes in contact with it instantly turns to steam in turn creating a jacket of steam around the projectile that separates it from the water. I wonder. Just a thought. Any one want to elaborate or offer any ideas or facts about this possibility that I haven’t considered. Of coarse I obviously realise the projectile would cool rather quickly, but still think it would initially have the same similar effect. What do you think?

    Since air is considered a liquid we should be able to achieve something similar given the right material.

    I wonder what would happen, or what it'd be like if a completely hydrophobic compound was painted onto a submarine? Except for where the passive, and active sonar, and microphones meet the hull... and possibly the screws as well.
    Or if you could adhere this hydrophobic stuff to the outside of the dried outside of an ice cube. Then quickly drop it in a glass of water. Especially if the ice cube didn't float to the surface, I wonder what would happen.

    Wouldn’t the collapse of the bubbles make a clear sound underwater and betray the presence of the projectile?

    ok, this may be a dumb question, but hypothetically, if a submarine WAS to coat a torpedo in a super hydrophobic material, wouldnt the resonation / turbulence / frequency of air behind it cause the radar to know with more accuracy where said torpedo is in the water?

    Now hear me out. Take the compressed air gun that is used to fire darts underwater, and add some hydrophobic powder to each dart. Now you have a ammunition that can travel much further distances underwater with the same amount of force

    Wonder if the military has any high tech coating on torpedoes to help them through the water, or at least certain parts coated to reduce drag but not so much that the torpedoes sorta "fall".
