    Suggestion: Put a microwave oven with some graphite in it into your big vacuum chamber, vacuum it down, refill with a mixture of hydrogen and methane, and turn on the microwave. Theoretically, it should deposit diamond on the graphite.

    Cody, I didn't have time to read all 759 comments, so someone may have already suggested this simple test. Place the stone in a cup of water and have it X-rayed (radiographed) at a local veterinarian's office. Vet's are easier to deal with than dentists or M.D.'s for experiments like this. If it is a diamond you would barely be able to see it; if it is a zircon it will stand out like a piece of lead (almost). Interesting video, as usual, Cody.

  • Mcchuggernaut
    Mcchuggernaut 2 months ago

    Cody man, that diamond isn't "a diamond". There are so many inclusions that it may as well be a piece of sedimentary rock made up of a diamond sand stuck together with a bunch of other crap. It isn't going to behave like a mostly pure diamond crystal lattice of the same size would behave. It will be MUCH weaker than a gem-quality diamond. If you stomp on a piece of sandstone, it will crumble to bits. Try the same thing with a solid quartz crystal (Which sandstone is primarily made of) and you will just break your foot. The water jet might not "cut" that stone, but it WILL blow out all the other junk holding that diamond sand together, either blasting it apart or appearing to "cut" it. Just my two cents for your consideration.

    • Mcchuggernaut
      Mcchuggernaut 12 days ago

      The definition of a diamond: A solid form of carbon with a diamond cubic crystal structure. This "rock" is what you call a "matrix" with diamond inclusions. And you are right, Cody is well educated, and a chemist. But do you know what I am? A computer tech grad with a minor in GEOLOGY. Sit down and shut up, you might learn something. Science is collaborative, and people specialize in different fields because it is impractical to be taught everything about every existing subject. That's why there are electricians, plumbers, and quantum physicists (instead of just generic "smart" or "skilled" people) doing specific jobs they are specially trained for. A physicist may be smart, but I might not want him wiring my house, fixing my toilet, or troubleshooting my computer.

    Hey Cody.
    Wikipedia says, that natural diamond has more than 5 times the thermal conductivity of copper - 2200 W/(K*m) vs ~401 W/(K*m) for copper.
    Monocrystalline isotopically pure diamond (99,9% C12) has thermal conductivity of 3320 W/(K*m).
    As far as I'm concerned, the latter value is higher than graphene, and highest known for a solid material at room temperature.

    Please explain the volume test. I don't understand it. How does displacing water in a cup increase it's mass if the rock is suspended by the wire.

  • Mshojat
    Mshojat 3 months ago

    I totally think that a water jet could for sure "cut" that. It might not cut it _straight_ but I still think that it would certainly break, since it's not a pure, "perfect" diamond, but rather full of cracks, holes/bubbles, and contaminants.

The problem is the sugars in the juice as and diabetes. Is there a way to pull the sugar out and replace it with a substitute like stevea or equil etc? So that I can enjoy some of my favorite beverages. So there's the idea/challenge I hope it's possible and you see fit to do it.

    i thought that would make for a really cool idea for a video. you should try to do it!!

    Hi Cody, hope you see this comment. As I saw you video about water boiling and freezing in vacuum, that was a very interesting experiment and I'm excited about that. However, I wonder that does this also work with other fluids that have different vapor pressures? For example alcohol, its boiling temperature decreases in vacuum but would it boil and then freeze like water does? And other fluids as well. Would be appreciated for your response

    Cody, you said something like "three point fifty-one". This really is a nonsense: you should say "three point five one". Fifty-one means "five tens plus one". What really mean to say is "five one-tenths and one one-hundredth". The two aren't the same. This was something I had drummed into my skull fifty years ago in school - I cannot believe that things have changed so dramatically in the interim.
