    Moving it
    Touching it
    Dispersing it in solution
    Leaving it undisturbed on a glass plate
    Exposing it to bright light
    Exposing it to X-rays
    Putting it in a spectrometer
    Turning on the spectrometer

    And my favorite...

    ABSOLUTELY NOTHING!

    Not ALL thiols stink! Yes, _most_ of them do, but there are a few quirks of chemistry that result in a very small number of odorless thiols: 1-dodecanethiol(1-do-DECane-thiol) and p-heptylphenylmethanethiol(p-heptyl-phenylMETHane-thiol). These compounds really only exist to make scientists synthesizing compounds that require either ethanethiol or benzylthiol less... unpleasant... like vomit inducing.

    I would’ve expected carfentanyl. Yes, a drug so potent that a single dose in a human is 1 micro-g. 20 micro-g will kill you for sure, even transdermally. Touching a microscopic crystal is certain death. Oh, and don’t forget that it kicks in almost instantly, and Naloxone isn’t strong enough, requiring you to give multiple doses, usually, just because taking thousands times the lethal dose, meaning you need about a thousand times a normal Naloxone dose. Yep. An overdose just like a heroin overdose that easily. It’s actually used for large animals like elephants to put them into anesthesia. That’s how strong it is. A milligram is impossible to survive, and again, something crazy like 85% transdermal bioavailability. Have fun!

    At least an honorary mention.
