I was so caffeinated while making this video that I didn't put in my Good Morning John and I'm having a fullon crisis....

Wait until Hank finds out vanilla soy milk lattes are just three bean soup
Love this so much!!!!
Not to forget, that US Dairy Industry lobbied Soy Milk to be called Nut Juice. I do not think they were inaccurate here.
Add chocolate. It's now four beans. (Kinda.)
@@mikapeltokorpi7671 I would drink nut juice. :3
Coffee technically isn’t a bean; it’s a berry pit.
It's actually a beautiful thing how hyped up you are about the stuff you think is interesting. When you listed off the plants and their places of origin around the 5 minute mark. That was just wonderful. Such good vibes.
Woah I came to leave this same comment
"The chemical plant"
Hank is so proud of himself for that.
Beats my answer of from the trees lol
I mean, it /got/ me, so... good joke.
Actually had my side hurting at how hard I laughed
I mean I sneered like a hyena so ya, good joke 😂
The chemis-tree
We owe these plants our lives, too. Not because of any medicinal benefits, but because for as long as we have been drinking them, they have been motivating us to boil our water before we drink it.
Thats such a good point.
This was a whole thing when building the transcontinental railway: the Chinese workers would get sick less often, because they'd drink tea instead of water, so they'd boil out any nasty stuff first.
Alternatively, the reason we started looking for things to make steeped drinks out of may very well be that it’s a little unpleasant to drink plain water hot.
@@napstadragon Interesting! This year, I read two separate articles on how 1) drinking various types of teas (long steeped black tea was most effective) can help reduce viral load of many different pathogens, including covid-19 and 2) boiling tea can reduce up to like 90% of microplastics in the water bc the microplastics cling to to each other and the tea leaves and are then very easily strained out.
Get that bag
Never looked at ATP and Caffeine so close together in time so I never noticed, but the minute you put it up right after, it hit me right away.
Learning that different sources of caffeine don’t have one single common evolutionary ancestor is not something I was expecting to learn. I’m one of today’s lucky 10,000.
Love being one of the 10,000 (high five)
But it does seem like they have a commonality from evolution; adonine.
I feel like videos like these definitely make the 10,000 spike.
Or maybe it doesn't count as the 10,000, since that basis is "things you think everyone knows"?
@@eisbaerauroraWhat’s that mean?
@@willtheprodigy3819 Look up the comic for XKCD 1053. The main part of it goes: For each thing that "everyone knows" by the time they're adults, every day on average there are 10,000 people hearing about it for the first time
1:16 "You might recognize it as one of the four nitrogenous bases". might doing a lot of heavy lifting in this sentence
I mean. I did. YMMV.
Surely everyone knows the chemical formulas for one or two feldspars!
I knew I saw Adenine's face before. Lovely girl. A bit toxic, but she brings a lot of energy to the party. 💐
Oh no my pun doesn't work 😂
@@melodiekayand quartz, of course 😂
kids these days don't know that you can watch Hank in a horizontal format
Its okay hank is great in many viewing formats.
Hank: am I on drugs right now
Bro you just ingested the world's most popular psychoactive substance seven ways
My thoughts exactly.
I was thinking “dude is not smart (like me) … tea is hot”
Eight, technically
I imagined John calmly sitting back in his chair watching this video, then jumping forward in anger after Hank said he didn't like Dr. Pepper.
🤣🤣
I’m angry at him drinking diet Dr Pepper
I can imagine they talk to each other while they are watching the video. If you verbally guessed out loud, what kind of plant the eighth plant was, so did John
@@jljordan1 genotoxic sucralose triggers inflammation
@@jljordan1 Is PepsiCo's "Diet Dr. Pepper" in the US the same as Coca-Cola's "Dr. Pepper zerooo" in the UK, or is is closer to diet colas where it's a different recipe that doesn't use sugar, rather than the regular recipe with the sugar removed?
I am subscriber of SciShow for more than a decade, and this is probably the first time I watch a video from this channel.
Now I know why this channel is so big.

@@bassbrother81 you guys
Welcome to today's 10000 lol
@Arkalen😂
This channel is so big because it was one of the OGs of YouTube in the 2000s, when YouTube was small enough that it had pretty much one self contained culture of celebrities with parasocial relationships to their viewers. Their fans were called Nerdfighters and the catchphrase was DFTBA “Don’t forget to be awesome”

He blew it. Unsubscribed.
Thats a really good one! Cheers

Yes. Absolutely. Trippy.
Totally thought this was a hankschannel video until he said "but John" 😂 Love Hank's science enthusiasm everywhere it appears!
That's because I didn't do my "Good Morning John!!" I'm freaking out...
@@vlogbrothersHank did you have caffeine in the making of this video? 😅
@@NerdfighterNicholehe had ALL the caffeine
Same! I was scrolling down to thumbs up the video, and got confused when I heard "but John" as I simultaneously saw the "vlogbrothers" name. 😅
@@melanyebagginsseems like it 🤣
never change, hank!! Thank you for so many years of knowledge enthusiasm!!
Oh wow — what a terrible time to be releasing an animated explainer about the pharmacology of caffeine next week lmao.
Okay, just speedwatched the video. No longer freaking out. It's like Hank knew all the deleted sections from my script and just made a video from those. Just wait till y'all hear about all the goofy details about your A2A receptors!
@@Clockworkbio Ooo! Exciting!! Subscribed.
Hi Clockwork! Love your stuff!
Lol, I was like - sounds real interesting, I'll subscribe > and I already am! 😅 Can't wait for next week!!
You speedwatched Hank?! I already feel like normalwatching Hank is speedwatching. Do you have superhuman processing capabilities? ✨
Just a note on caffeine yielded from decaffeination: there’s no additional flavour here, the caffeine is carefully refined as part of the process. Coffee is decaffeinated before roasting (where most of the flavour is created). This kind of caffeine is usually labelled on products as “natural caffeine” - though it’s obviously identical to synthetic caffeine.
Also, I will accept coffee is a soup long before I will accept coffee is a tea.
(You can actually buy coffee leaves prepared for tea making but it’s… not good)
Didn't expect mr Hoffmann to be here. Thanks for this information!
This is Mr. Coffee speaking FYI
coffee leaf extracts can actually be tasty, but not really available
coffee leaf tea, I wonder how... not good it is
wouldn't it be more of a broth than a soup?
As a barista I found an incredibly interesting thought enter my brain one day…I am a state sanctioned drug dealer. Various growers from a foreign country process a raw drug that is then smuggled across the u.s. border to distributors who then sell whole sale to dealers and cooks, who process it into smaller batches to distribute to the street level sellers, who then process it further into a smaller package to sell to addicts who literally show up every morning to get their fix. And they all have their favorite dealers, and they sometimes give me extra money because they like my shit and wanna keep that fix going.
I am 100% expecting John to talk about caffeines connection with TB now
You've heard of ATP? Let me tell you about a TB!
If coffee is TB, I'm going to lose it.
Why do you think the urban populations of England (and thebindustrialising world more generally) took to drinking boiled drinks so much? Caffeine (for weird working hours) + TB free drink (TB began to thrive in the poor sanitation of new urban populations.
Studies have shown a correlation between populations drinking more tea and having less TB.
I mean he has talked about Dr Pepper & TB...does that count?
I think he might have mentioned that people used to think having coffee and sweets as a child could give them TB (maybe that's not caffeine-related enough)
Plants: develops a mucous membrane irritant capsaicin to deter animals from eating its fruit.

I’ve suffered from canker sores since I was 10 years old. It took me 30 years to reach the conclusion that caffeine is the cause. I realized that if I drink not only coffee but also tea, yerba mate, or guaraná, within a few days a small canker sore appears. If I stop consuming caffeine at that point, the canker sore lasts only a few days and isn’t painful. But if I continue consuming caffeine, the canker sore grows and becomes very painful. I hope this helps someone who suffers from the same problem as I do!
I suspected that caffeine was causing some canker sores inside my mouth as well. It's great getting confirmation from someone else that they have similar symptoms.
Oh wow do you think it’s the acidity?
I had this suspicion, but I figured it was correlation not causation.
We need a scientist to look into this for us 😂
@@timmontagjr.3171no you don’t, you can do it yourself. Make a phone note, write when you drink caffeine, and then write whether a sore appears within a chosen amount of time.
The truth will become clear to you very quickly. You don’t need anyone else to do it for you.
I have a PhD in plant molecular biology and I learned something new about Adenine molecule today. Thanks Hank 👍
“Try to learn something new every day” is still good advice, even in one’s PhD years.
I haven't watched the video yet, but I thought it was adenosine that was affected by caffeine.
Your PhD seems to have been lacking a bit then
@@zerospace101phds are so hyper focused to really determine that, could have just been a different subject of study in the field
Honestly, you should know more about that
College has become a participation trophy
5:55 "I like tea because there's less caffiene per drink, which is great for me, and there's also more theophyline, which is a milder vibe."
5 SECONDS LATER
6:00 "I'm sweaty! Jeez! What's- am I on drugs right now?"
Love that cut.
Heh...i guess technically we are 😅
Depends on tea and coffee.
YOU DID IT! Thank you!. I asked your guys to give me a different random tea each month instead of having to buy 6 months of different tea at once and you've done it! Thanks, again
Hank was so zazzed from the tea that he forgot "good morning, john"😭
0:11 Slight correction, Yaupon is actually (fairly) closely related to Yerba Mate, as they both come from plants in the Holly genus, Ilex. Though considering how big Plant genera are that doesn't necessarily mean as much as you might think.
I was just about to write this comment! I do R&D for a tea company, and we group Yerba Mate, Guayusa, and Yaupon together as a "tea category" because of the shared genus and overall similarities in terms of taste and function.
Yup. Ilex Vomitorious is yaupon holly, ilex paraguarienses is Mate.
Another is that coffee is a tisane. Tea is a tisane made with tea.
I remember learning about it growing up in Texas and it was strange to me how the Yaupon Holly is grew so widely and is used as an ornamental when it can be made into (imo) a slightly earthier version of “regular” tea. It’s unfortunate it was never widely adopted in modern times in the way that sweet iced tea could’ve referred to Yaupon tea. Too bad the traditional practices were misunderstood and the stigma stuck.
I don’t live in Texas anymore but Yaupon tea is nice to have and recommend people give it a try.
They're very closely related even compared to other species in the same genus.
Your enthusiasm is absolutely infectious. Don’t Change.
0:32 So it's completely plausible that the Raktajino comes from a plant that independently developed Caffeine on the Klingon homeworld. Fascinating!
Thank you for leaving the best comment
TIL that my favourite beverage that I've never tasted, isn't indigenous to Bajor, but Kronos instead!
I'm more into Stargate (for some real-life historical reasons), but the idea that sentient creatures in any setting part-taking in caffeine is 100% plausible is very interesting and very new for me
@@2Adapt Qapla`!
Love this take
Did I just watch a very interesting and cleverly disguised 7:14 minute advertisement for tea?
It was the whole thing buddy, its all an ad, always has been. The dirt is an ad for plants, and stars are an ad for solar systems.
The key is to stop the video when he says "I have created an experience", you still get all the cool facts about adenine and parallel evolution and no marketing
No he just expects alien invasion. And you guessed it ! Caffeine kills bugs...
Of all of the things someone can hawk on their viewers, an $18 tea subscription that 100% goes to cancer research is about the absolute least egregious.
@@Graviticus Sure, and coffeee grows on trees, right.
I NEED that LTheiene video from u PLEASE! PLEASE? I mean...and Thank you so much for your time and effort! U r awesome sir!
6:11 Please make a video digging deeper into that, that would be so informative!
Agreed!
Yes, this would explain so much about why I swear the caffeine buzz from tea feels different than the one from coffee
Tea is the most amazing drink ever
Agreed
Just take 100mg or a 200mg l-theanine capsule when you drink your coffee. Pretty well known.. known about it for like a decade. I get them from vitamin shoppe
7:00 QuantiTEA?
QualiTEA over QuantiTEA.
This video explains so much about Hank.
Hank's new Dropout show: Very Important Molecule
I would love for Dropout to do some sort of science comedy show like that, even if they couldn't afford Hank specifically (as we all know he's a very busy bee)
The "Nobody Asked" is kinda science comedy adjacent if you haven't tried that one. They don't promote it much😕
New Vehicular name just dropped XD
I'm so on board! That would be addicting to watch 🧡
@@3countylaugh I loved "Nobody Asked"!
A video on the interaction between L-theanine and caffeine would be great. Some Japanese teas like Matcha and Gyokuro are intentionally grown in some amount of shade to enhance the umami flavor, which comes from the L-theanine. This may also be why these specific teas tend to be known for their calming, yet energizing effects.
My go-to non-coffee caffeine source, GamerSupps, includes both PurCaf - derived from coffee beans and intended to be a non-synthetic replacement for synthetic caffeine - and L-Theanine, so I too would be interested in this.
I once used matcha to stay awake for 96 hours while trying to remain productive for that entire 96 hours (a cup every 4 hours). It worked... of course it took me like a week to re-establish a normal sleeping routine, but hey, it was an experiment.
I tried the same experiment with coffee and felt completely fried and useless after about 60 hours.
Ohhhhh, so maybe that's why I like Chinese-grown green tea, but not matcha (I dislike umami - yes, this is weird).
I once worked at a small teashop where we were told not to say the word "coffee" bc we didn't sell it. If we just had to talk about it between ourselves, we were supposed to say "bean tea".
We weren't allowed to keep out bean tea anywhere other than the kitchen bc even the smell was forbidden in the tea room.
5:28 I was right!!
I genuinely laughed out loud when he said that
This is the perfect talking speed for me to be extremely entertained while also causing me to forget everything after 5 seconds
Grateful for every day Hank continues to share his knowledge 🙏
Please make the "other whole video about it" that you're teasing us about, love learning more about tea!
Yes, please, Please, PLEASE? 🙏🏽
Hank: "What plant do you think the caffeine in soda comes from?"
Me, confidently and audibly: "The coca leaf."
Hank: "THE CHEMICAL PLANT"
Me: profuse coughing laughter
I mean, Coca-cola literally comes form coca and kola, so you're almost right. Colas originally had caffeine from kola nuts which were already in the list he made. But we just don't do that any more so the 8th member of the list is kinda cheating.
Coca has chemistry other than caffeine...which is no longer legal 😇
@@evildude109Fun fact: the US government once sued to try to get Coca-Cola to remove all the caffeine from their products in a case hilariously titled “United States v. Forty Barrels and Twenty Kegs of Coca-Cola”. They initially lost, but it eventually made its way up to the Supreme Court, who overturned the ruling and sent it back to the lower courts. Afterwards, Coca-Cola opted to voluntarily reduce the amount of caffeine and settle with the government.
I think most people are unaware of just how shitfaced everybody was before hot tea became another way to drink uncontaminated water. Truly something that I don't think is brought up enough when studying our history.
edit: Methods of refinement weren't much of a thing, if at all, during these times, so alcohol percentages were lower. I might just be making this up, but for some reason I have it in my head that the "Pilgrims", as we call them, were drinking 2-3% ciders. Constantly. Like, literally, everyday, all of the time. All. Of. The. Time.
alchohol doesn’t seem like it’s be great for hydration
@@Cadet1249 sometimes liquid is liquid. You may not be hydrated but you drank something and also you didn't die or puke/diarrhea your innards out.
It didn't do quite as good a job as fermentation, but sometimes good enough. Quinine also says hi.
@@Cadet1249it was very week. 1-2%.
If you put plant parts in boiling water it's a soup. Coffee is soup, tea is soup, IT'S ALL SOUP!
If you strain out the solids and only drink the liquid, it's a Broth.
Coffee is a Broth.
Or maybe soup is just chunky tea 🤔
@@zim6525 true, but many broths are also considered soups.

I spent 25 years being treated with Lithium for Bipolar II when actually I was just sensitive to coffee. Ever since I've avoided all sources of caffeine and have generally been very stable.
Not enough people talk about this! I was diagnosed when I was young, but now as an unmedicated adult who avoids caffeine, I basically fit right in with the masses... mostly...
Can you elaborate on which symptoms were aggravated by caffeine?
@@danielamaya5241 I first started having having mood issues when I began drinking coffee in earnest in 2nd year university. It was severe enough to seek medical help. When I was 28 I was put on Imipramine, an old style tricyclic antidepressant. I promptly went manic and was eventually hospitalized. It was that point I was put on Lithium as they figured I was Bipolar II. The mood issues continued to get worse, and by the time I was 45 60% of the time I was in deep clinical depression, 20% normal mood, and 20% hypomania. I couldn't work. I couldn't keep a relationship. At 45 I quit coffee cold turkey as part of an effort to fix some stomach issues i was having. Quitting didn't help with that, but my depression cleared after 3 days and has never come back, neither has the hypomania. I've been mood normal since.
I have to qualify that statement by saying that, unsurprisingly, I've discovered that my mood is sensitive to a variety of substances. Lomotil, Imodium, grape seed oil, L-Tryptophan, all quickly induce mood changes after ingestion. Lomotil, one tiny almost invisible 2mg pill, has me flying into hypomania within an hour after taking it. L-Tryptophan was like pouring gasoline into my brainpan and lighting on fire.
Absent these triggers I'm dead mood stable. Go figure eh? Self-poisoning myself all those years. Coffee was always in my system the first half of my adult life, so I was always mood sick. I haven't touched the stuff since 2008, except for a one cup experiment 5 years that went extremely poorly.
@@danielamaya5241 While on coffee I was 60% hypomanic, 20% normal mood and 20% hypomanic, with a couple of instances of what I would consider full on mania. In later years I found other substances that also produced bipolar symptoms: lomotil, Imodium, L-Tryptophan, and grapeseed oil. Absent all those substances I don't have a mood disorder and would never darkened a psychiatrist's door.
@@danielamaya5241 Ok, this is my third time time trying to reply to your question. While I was on coffee I was 60% depressed, 20% normal mood and 20% hypomanic, with a couple of instances of full-on mania. That all stopped on Day 3 of quitting coffee and it never returned.
Essentially I became a non-bipolar person.
I’m so glad you exist ❤
I thought you were specifically going to take down Rockstar, which is my favorite energy drink. Instead, I remembered about 5 seconds in the function of caffeine in plants.
Love it!
6:43 Okay, but I’d love monthly videos of Hank trying to calm down.
I genuinely was slightly disappointed when it became clear the monthly videos were in fact not Hank trying to calm down.
That seems like it'd be a great way to sip some tea
Guided sciencey meditation with Yogi Hank does sound incredible ngl
I also want videos where Hank is going to talk about how to calm down for a second.
Then he mentions "the koala tea of the tea."
Yeah, I was really confused when he started talking about what the videos were about, when he had already said they were him trying to calm down.
Buzzed bees! 🤣
Yaupon grows wild in my area and I’m glad to have discovered it. The way I roast and dry it is on a candle/cup warmer plate for several hours.
