How interesting! Can you tell me how one would theoretically build a cobalt bomb inside their garage...for educational purposes of course.

/j and in Minecraft

I don't want to get banned for trying to do warcrimes again.

You probably won't be able to get enough material for a true cobalt bomb.

What you could do, however, is build a Farnsworth fusor. That's very doable in a basement using...relatively easily acquired parts. As long as you keep the operating voltage under 30kV you won't need lead shielding, but you won't be getting many neutrons either. Get a couple plates of lead, get yourself a bunch of cobalt salts (ask someone that does glass art) and put them in the reactor chamber. Then crank that bitch up as high as your transformer will let you, and soon you'll have radioactive cobalt. Then you go to a gun store and buy a block of tannerite, US gun culture makes this a commonly available explosive, and tape the cobalt to it.

Now you have a salted dirty bomb.

If you're feeling really lucky, you could try modifying a time-of-flight mass spectrometer to integrate into your reactor chamber vacuum output, allowing you to collect reasonably pure tritium in tiny amounts. Get enough of that, add some deuterium, figure out a way to ignite it, and you have a thermonuclear device.

Edit: if you manage to pull off any of this, that will be impressive. Reach out to your local university, and collect an honorary degree in mechanical, electrical, or nuclear engineering.

A community for your defence shitposting needs

Rules

1. Be niceDo not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.

2. Explain incorrect defense articles and takes

If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.

3. Content must be relevant

Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.

4. No racism / hatespeech

No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.

5. No politics

We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.

6. No seriousposting

We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.

7. No classified material

Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.

8. Source artwork

If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.

9. No low-effort posts

No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.

10. Don't get us banned

No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.

11. No misinformation

NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.
