    I already did some planning for the watermelon. Seems that it's going to be about 65 bars at room temperature with co2 there. Maybe 3-4 days should be enough to make it saturate and then quick decrompession for explody results :D I try to get it out next week!
    Also just realised that I have the wrong intro :D I was planning to release this on HPC first but I have too long line of ideas there :D

    It probably did not cause any spectacular effects because the meat has no blood circulation. Also the longs have a lot of surface area to dissolve gasses in the blood and from their into the surrounding tissue. I don't know how you could replicate that.

  • @nullptr472
    @nullptr472 13 วันที่ผ่านมา +13

    Mixing some gelatin and letting it set in the pressurized chamber could be interesting. The more solid-structure of gelatin may allow the buildup of bubbles to be more visible as it would likely either 1. explode or 2. capture the gasses in bubbles internally which may then be visible by passing light through the decompressed gelatin
    edit: apparently someone wrote a paper covering this: "Quasistatic growth of bubbles in a gelatin gel under dissolved-gas supersaturation". my non scientific take away is that you'd want the gelatin solution to be as week as possible (as a stronger solution inhibits the growth of the bubbles) and you may need to add some energy to the system to trigger bubble formation

    I think that shimmering was the beginning of a dimensional rift forming. It's lucky you didn't add any more pressure as the results would be unpredictable. You only got some strange acoustic effect, like from about 9:30 you could hear your past self talking about the experiment. 👀

    Just for information, bottled gases are notoriously wet, it's fine for a lot of industrial applications but not for specialist applications. Where I worked, to get dry nitrogen we used an evaporator and liquid nitrogen. Dry ice should give a good way of getting nice dry co2 :)

      @bueb8674 11 วันที่ผ่านมา +3

      At high pressure the gas is much 'thicker' and slight temperature or density variations refracts light quite noticeably, especially while mixing gasses(Nitrogen in air) there will be a lot of density variation until they mix thoroughly.

    Actually, small air bubbles are perfectly safe in your veins. I've been on IV drips before where I've literally watched an air bubble flow through the line and into my arm. Of course with the myth of how little air it takes in your veins to kill you, this freaked me out. But the doctor reassured me it was a normal thing with IVs and perfectly safe. And I'm prefectly fine. Even though contents of the bag are vacuum sealed, when they connect the lines, a small amount of air gets in. It's no big deal. A 10cc syringe full of air on the other hand might be a different story.

    The reason you can be killed by DCS (Decompression Sickness, aka the Bends) is because the Nitrogen bubbles that form in the blood stream obstructs circulation. A slab of meat with no blood flow is really non suitable human analog.
