Top 10 Dangerous Substances That Will Straight-Up Kill You 

I worked in a chemical lab, and although you certainly didn't want sulfuric acid splashed on you, the stuff we feared the most was Hydrofluoric acid. That stuff goes through your tissues and dissolves your bones. Very nasty stuff.

"If captured it will cause death in 9 seconds" "Great. But how exactly do I get them to take it." LMAO what a legend.

Thanks, I'm gonna try all these! :D

Than you for giving me more options than bleach! THANKS!

Anything my ex-wife cooked ...

well,got my grocery list down now

Thanks for the tips! Love your videos!

I was looking for this, thanks.

finally watchmojo,iwas just searching something that can cause painless death and yet this shows up in my subcriptionsm.thank you

#5 cyanide, the guy inside the tube, He played the creepy murderer in no country for old men correct?

thanks I really needed this

This video was very........... informative.....

number 1 should be love

WatchMojo you guys just never disappoint for entertainment haha

Thanks for some good advices, WatchMojo!

Thanks for the tips

Many schools built before 1980 in my city still have asbestos!

Finally. A list for me

Thanks this was super helpful

Great video. Thanks for mentioning the different modes of entry into the body. +Kyle Serie, bleach is not nearly as bad as these chemicals. She did mention chlorine gas, which, like bleach, is chlorine based. It is less toxic than these other chemicals.

Bleach better be on here

i remember i used to eat tuna nearly every day as a kid and i had to go to the doctor (because of the mercury) who prescribed me with not being allowed to eat tuna more than three times a week

thanks for the info

thank you for the inspiration

I'm so glad WM has a good Lead.

Top 10 names to write in the Death Note.

i love this channel!

Gotta go out shopping for some of these substances now.

There's a certain isotope of cobalt that is extremely harmful. It emits twice the amount of gamma radiation. Gamma radiation basically turns the insides of people into mulch. Essentially punching holes into the molecules of a person's body. If you watch any movie where the victim of radiation is vomiting white stuff, that white stuff is the stomach itself due to the gamma radiation. This particular isotope of cobalt can be found in crud which is a byproduct of reactors. It's rare and as long as the cobalt is inside the crud, it's not a problem. But just a tiny bit of the cobalt is 100% fatal when exposed

as a suicidal man this really helps! thanks Watchmojo 👌👍

Thank you for posting this, I was thinking on an easy and painless way to go out, since I found out some terrible personal news... people do suffer, and I wont take it anymore.

#4, Cesium (or Caesium) is the most reactive stable element on the periodic table of chemical elements (besides Francium of course). It reacts violently with water, exploding the instant the metal touches it. It's so sensitive that even the moisture in the air makes it catch fire (it's the most pyrophoric [pi-row-FOR-ik] substance we know of). It's also so dangerous to have around, that it needs to be transported in a glass ampuole under Argon or Xenon, contained within a pipe bomb, wrapped in tissue and bubble wrap and placed carefully in a small box with FRAGILE and DANGER plastered onto it. It's melting point is so close to room temperature that just holding the ampuole in your hand can melt the metal into what looks like liquid gold. It's also quite expensive (look it up, it's kind of crazy). Cesium has a variety of uses that use only a small amount, such as atomic time. I'm kind of a nerd. I know this kind of stuff. WatchMojo.com failed to mention some of these facts (and I also corrected a mistake). You're welcome.

Last time is was this early... Show more

You know another thing that will straight up kill me.... ...is watchmojo....

I once worked for a semiconductor (computer chip) manufacturing company, as a chemical technician. My duties were mainly to keep the “tools” stocked with the chemicals used in the chip making process. I placed tools in quotes because although “tools” is the industry name for the machine, it is basically a million dollar+ robot. Anyways, many of these machines use highly, HIGHLY caustic, corrosive and acidic substances. While many were very dangerous in their own right, the most terrifying to me was Hydrochloric Acid. It’s so dangerous, that if this chemical in its liquid state comes in contact with as little as 20% of the human body, you have about a 10% chance of surviving. The reason for this is that Hydrochloric acid has a a natural chemical attraction to calcium as it attempts to complete a molecular bond. As our bones are comprised of calcium, this acid will eat it’s way through the skin and muscles until reaching the skeleton. Fortunately there is a calcium jelly that can be used to temporarily neutralize the chemical reaction. However it’s far from capable of saving your life. The only thing you can hope for, is making it to a hospital that has the capability to deal with severe chemical burns. Needless to say, I worked this job for a short period of time before finding something that I wasn’t literally risking my life every day for $12/hr.

I actually thought VX would be on here. That stuff is legendary.

where can i buy myself some of these lovely substances

Di-hydrogen monoxide!

My grandfather's house that my mom grew up in has asbestos siding on it. After he died the new owners wanted to remove it but found out that it was really expensive to do because of the special procedures that had to be done. They eventually sold it and the owners now just put vinyl siding over the asbestos siding.

i watch u so much I'll just subscribe

Thanks for the shopping list

"Plutonium doesn't exist in nature". Yes it does, just in very small amounts.

This gave me some good ideas.

Looks like I know wat to buy next time I go to the store..

I sold my gun and have been looking for effective ways to end my life. Thanks _Watch Mojo,_ I've been desperate to find fast remedies.

What about francium? It might only have a half-life of 20 minutes, but it is even more reactive than caesium.

FINALLY!! Watchmojo I applaud this video.

Thanks for the tips bye

Fluroantimonic acid. The most powerful acid known to humanity. It is 10^16 (10 quadrillion) times more powerful than 100% pure sulphuric acid, it eats glass, concrete, it burns things that have already been burned (i.e. ash), and it reacts violently upon contact with water. Fun stuff. Not much is known about the chemical because it is so hard to work with, and as far as I know there are currently no uses for it, and there is no known way to extinguish fires caused by this acid, because it will burn the extinguishing compound too. The only safe way to store it, is in Teflon coated containers, Teflon itself being effectively a byproduct of another superacid - hydrofluoric acid. Speaking of hydrofluoric acid. It’s not quite as awesome as fluroantimonic acid, but still pretty gnarly. If you get it on your skin, you won’t know until 24 hours after it’s too late. The reason for this, is that the acid LOVES calcium. It won’t eat your skin, so much as penetrate your skin and it will eat your bones from the inside out. Because this acid is used so widely in computer pcb and Teflon manufacture for example, there are essentially epipens of an antidote which is basically a calcium gel (calcium gluconate to be exact) so the acid will prefer to eat that instead of your bones. It also dissolves glass. Oh yeah, the treatment regiment. If you are unlucky enough to get a hydrofluoric acid burn, the treatment guidelines specify that under absolutely no circumstances is the victim to be given absolutely any pain relief whatsoever. The reason why, is because they know that when it stops hurting, you’ll probably be ok. The safest form of this acid, is in a dental gel. That’s right - dentists use this shit IN YOUR MOUTH. It’s used to roughen up (read: eat) the surfaces of your tooth so that fillings stick better. It’s concentration in dental form is 9.6%, which is still plenty to do fun stuff with (like eat the plastic and glass layers of computer chips to expose what’s beneath). Azidoazide azide. The most explosive substance in existence. It explodes when heated, cooled, touched, moved, left on a table in a climate controlled room, upon contact with light, and, it explodes for quite literally no reason. It is so explosive that, again, not much is known about it, because it is so hard to do experiments on.

OMFG they forgot Dihydrogen Monoxide!

Sulfuric acid really isn't that bad. I once returned to the lab at my job back then to fetch my notes that I left there, while my coworker next to me worked with concentrated sulfuric acid, a test tube and a heater. Long story short: He worked with an air tight system, in which he sealed the corks but forgot to open the valve necessary for the wanted reaction. The test tube logically exploded, since the pressure had no other way of decreasing. I did not wear a lab coat, since my work time was over. So yeah.. Glass shards covered in sulfuric acid were sticking out of my arm and had to be removed and neutralized. I still have some scars, but would it have been phosphoric acid or nitric acid, the scaring would have been much worse. And, in the case of phosphoric acid, my elbow might have caught on fire. :3

I forgot did they mention RICEN made from Castor Oil/Beans? Was that not used to assisnate a Person of interest with the Tip of a Poison Umbrella?

Anything my mom fucking cooks

Thanks for the ideas for me to end my suffering.

Last time I was this early, WatchMojo had good content

*favorites for future use*

My dad was a furnace man. In the 1950's and 60's, furnaces used to be full of asbestos. He would haul out furnaces loaded with asbestos. No protection. When he was in his 50's, he was constantly getting all kinds of illness, probably related to asbestos. He suffered for 2 decades, then he died of medical errors.

Dihydrogen Monoxide

Dad died of Asbestos cancer so that was very emotional for me seeing that again :(

Probably asbestos and lead. I live in an area that has horrible water that I have to filter before I drink it. I live in a building that was built back in the 1930s, so asbestos is a very real possibility. I don't know how possible it is for Yellowstone Park to blow it's top but that would be another concern that is way down the list of possibilities.

FYI for us normal people, @7:44 -177 degrees Fahrenheit is -116 degrees Celsius :)

you forgot the most dangerous substance: loveuuuugggghhhh

Do a top 10 most flammable substances, plase!

Omg, I freaking died when they mentioned Sherlock at 11:20 😍😍😍

who else thought of spongebob when they heard uranium

It's like youtube knows that I've been watching videos about depression and thought "I think he'll find this video inspiring".

considering I live in Lebanon where apparently there is Sarin. I'm scared most about that

Thanks mojo.. now i have to listen to Radioactive all day. lol

Hydrofluoric acid

omg man you're releasing a video every single minute wtf man? are you out of your minds?

"Are you sure it was yellow cake?" "You don't believe me, I got it wrapped up in this special CIA napkin"

During the Asbestos segment, I was kinda hoping for a Portal 2 reference

I would be more afraid of the Black Mold

Thumbs down for scientific inaccuracy

they have started making every top ten that pops into their mind

thanks

Watchmojo at its boredest

Uh, in the movie "The Boy In Striped Pajamas," they used Zyklon-b

The new house me and my family is moving to has a good view of three mile island from a big distance.

I believe this is a subliminal message to everyone who keeps saying that WatchMojo is running out of ideas

Why isn't my wife's cooking on this list?

i have 10 more ways to die now yay

Thanks... Where do I get these though?

do top 10 most beige wallpapers next pls

What about russian cs:go players?

dont mind me... im just here incase i fail my exames

Oh look they got sarin. For those who don’t know sarin has the ability to kill every person on earth by muscle spasms but if you live you will make a full recovery.

My mixtape blows up when it comes in contact with air too that's why I haven't droped it yet

This video IS COMPLETELY AND TOTALLY WRONG in ALL INFINATE levels possible and impossible! The NUMBER ONE KILLER AND UNDISPUTED CHAMPION OF ALL TYPES OF DEATH, IMAGINABLE AND UNIMAGINABLE, THINKABLE AND UNTHINKABLE! SINCE BEFORE THE BIRTH OF THE UNIVERSE ITSELF IS: Life.

Anything my ex-husband cooked me...

There is a scale of toxicity which would have been useful in this comparison: LD-50, or Lethal Dose 50%. The amount of material which kills 50 out of 100 of a particular animal per specific body weight. The lower the LD-50 (grams, grains) the higher the toxicity. It was invented in 1927 and has recently been phased out, but it is still a useful tool for comparison.

Castle, my fav show... I miss it 😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭

I just realized that the mojo part in watchmojo.com logo is a smiley face

3:00 # 8 lead ( Really 💥🔫) Hahahahahahahahahahahahah

What about DC-2 from Planet Terror?? That shit was crazy

What about fluoroantimonic acid? It can burn through literally anything except specially designed containers made specifically to hold it.

Clarification on the asbestos topic... while countries may have banned new use, it is still in buildings all over the place, including hospitals, even though previous employees were negatively impacted by the exposure!

3:56 Omg the flint problem is so old now!

Just three weeks ago the flat above me had some Asbestos removed. 2018 and they still hadn't moved it.

the editing on this video was hilarious
