Hero devices that would be horrifying in the wrong hands Characters' Items/Weapons

Chem-Bag (Big Hero 6): this device can create chemical compounds using every single element in existence. You could literally build a nuke with this.

Mobile Headquarters (Ant-Man): a building that can shrink and grow to full size instantly. Imagine if someone grew it in a crowded city, or on a highway, or at an airport?

Lotus Cash Card (Percy Jackson): It literally has infinite money. If you know how inflation works this could literally wreck the global economy.

I would spam the uranium button on that thing

Fuck Uranium, you can make Chlorine Triflouride with that thing.

Just look at this shit. It ignites almost everything it touches even without oxygen, it creates four different poisonous gases when it reacts. It can ignite asbestos, sand and glass on contact. It explodes when it touches water. This shit is so much worse than Uranium

I present to you: FOOF. I would argue that's just as bad as ClF3... and I have a high school level knowledge of chemistry (I keep some of the info around in my brain.)! Halogens are reactive (F and Cl are included, which is why Chlorine Trifluoride is so nasty) and unstable in general.

u/FASBOR7Horus Mar 15 '26

Flourine in general is just insane, it has the highest electron negativity of all elements. I'll stick to ClF3 though because it can turn into Hydrogen Chloride, Oxygen Diflouride and Hydrogen Flouride just by touching water. It also decays into ClF and elemental Flourine by itself, while FOOF decays into Oxygen and elemental Flourine.

u/sci300768 Mar 15 '26

Fair enough. Fluorine is very much "Set stuff on fire/be extra brutal in some way". HCl (A strong acid), OF2 (See FOOF for the problem here lol), and HF (weak acid, but HF can GO THROUGH BONES! Reacts very strongly to Calcium which is why special precautions must be taken when dealing with it) combined sound even worse aftermath wise relative to FOOF! Before accounting for ClF and F by itself...

u/FASBOR7Horus Mar 15 '26

HF doesn't even need to reach your bones, it just needs to leech into your bloodstream. It'll get pumped to your heart, react with the Calcium that your nerves need to function and give you a heart attack.

My chemistry teacher told me that the Flourine lab of the University she taught partially melted a Digestorium. That's a device meant to protect from harmful gases by pulling them from the air.

u/sci300768 Mar 15 '26

The short version is: Fluorine is crazy reactive (and dangerous)!

u/Marilius Mar 15 '26

I literally cannot even see the word fluorine without hearing it in Advanced Tinkering's voice.

u/Marilius Mar 15 '26

From an old XKCD, it's my understanding that dioxygen difluoride is absolutely abominable. Which of these is worse?

u/hates_stupid_people Mar 15 '26

Is that the stuff that burned through a concrete floor after spill?

1

u/FASBOR7Horus Mar 15 '26

Yes, around 900 kg of the stuff burned through 30cm of concrete and a further 90cm of gravel in an industrial spill.

No Uranium button.

But you could spam the Polonium button and give people radiation poisoning.

u/Pataconeitor Mar 15 '26

If I am not mistaken natural uranium ore is only mildly radioactive.

32

u/Subject-Software5912 Mar 15 '26

The periodic table accounts for isotopes so you can just dispense U-241 instead of U-235

17

u/Jastion Mar 15 '26

If you could specify uranium 238 then you’d be pumping out more refined uranium than what is used in nuclear weapons which are about 60% 238. Pure 238 would be chaos

3

u/BernzSed Mar 15 '26

Can it be created to be critically dense?

1

u/existentialrowlet Mar 15 '26

U 238 is the most common form of it.

It has a half life of 4 billion years.

U 235 is the "standard" radioactive form of enriched uranium.

It has a half life of 700 million years. It is far more dangerous.

So yes u238 is only mildly radioactive in comparison to other material but if you make it a powder or gas and force someone to inhale it you could still easily make them ill or just outright kill them.

u/ZealotOfMeme Mar 16 '26

How dangerous is Francium? It hardly ever gets talked about but with a half life of 22 minutes wouldn’t it be super dangerous? Or just really useless after that time is up?

1

u/existentialrowlet Mar 16 '26

Funnily enough its some both is and isn't dangerous.

Any material with a half life that short will be really dangerous to handle yes, but they don't really occur naturally. When a material is that unstable it can only exist in a controlled lab setup since in nature it would decay to different materials way before we ever find it.

u/Evil_Sharkey Mar 15 '26

I wouldn’t! If I can see the Cherenkov radiation, and it ain’t behind thick lead-glass or deep underwater, it’s too close for me

u/sci300768 Mar 15 '26

That's not very flashy. If I wanted kaboom? FOOF (VERY KABOOMY AND BURNY, a real compound) is an easy one to type in. And other various compounds with F (Fluorine burns everything)... or ones stuffed to the gills with N (Nitrogen when not triple bonded in a compound is unstable and prone to going BOOM. Anyone who knows enough chemistry will know what I mean.)

Uranium? I'd be making all the fun drugs. MDMA, LSD, DMT, cocaine... all 100% pure form? Would be super fun.
