    The two most dangerous chemicals are Pb and Fe. More people have been killed with lead bullets and steel blades.

    Buying it McDonald's
    Cuddling with it
    Having some sexy time with it
    Leaving it undisturbed
    Agreeing with it
    Leaving the toilet seat up
    Absolutely nothing !!

    HF and it's ilk (like the last chemical you mentioned, the acid) won't kill you by eating away your bones. You'll be dead long before that. It will leach the calcium out of your blood. Calcium is an important electrolyte for your heart to function... No calcium in the blood, no heart function. I leave it to the reader to fully reduce that formula...

    Botulinum is more dangerous than anything in this list, one billionth of a gram or one nanogram will easily kill you and one gram in a water supply can kill everyone who drinks from the water supply.

    Could Chlorinetrifloryde be stored in something such as glass or more reactive containers if the inside of said storage unit were coated with teflon? I just know that it's a pretty good method for storing other fluorine-based solutions to use teflon. Thought it might work here. Any insight?
    Also, I love yall's show(s).

    I want somebody to make a similar list for all people who are afraid of Chemicals in their food (no joke, they exist... and they got facebook communities on their own small facebook pages), but instead of these chemicals, I want the most vital ones to be on it, such as Dihydrogen Monoxide and Sodium Chloride. Of course mark it as being extremely dangerous to human health and have fun in your local mall whenever one of them tries to avoid them in their food 😂😂😂

    one chemical that's missing from this list is FOOF, Dioxide difluoride.. It's like the offspring of many of the chemicals on the list with the added bonus that it can even react at cryogenic temperatures below -200C (-330F)

    Botulinum toxin type H is the actual most toxic chemical in the world. inhaling as much as 13ng (13 billionths of a gram) will kill you, and if thats not bad enough one drop the size of a red blood cell will kill all 700 trillion cells in your body.

    Scientist Hank talks about all these chemicals like he has witnessed their effects first-hand. When talking about Thioacetone, the expression on his face tells me he walked into a room filled with its fumes. Then later about fluoroantimonic acid, he speaks about how the "fluorine will burn through your bones" like its a spa treatment he recommends.

    And to anyone who says that thioacetone isn't actually dangerous, it's listed on Wikipedia under "List of Extremely Hazardous Substances" because it can also cause people to pass out. In fact, all of them are but Azidoazide Azide and Dimethylcadmium don't actually have pages on Wikipedia, so they're listed but there's no more information on Wikipedia about them.
