They were very professional and a pleasure to work with.
We didn't work any kind of deal with them. We paid their standard rate for a group our size.

I hope you enjoy this video. Ever since I watched Brady's video about 10 years ago this has been in my mind. I'm grateful Brady was cool with me recreating it.
If you're a Patron of Smarter Every Day, go check this post! I'll attach some of my film photos from the hike to it. I'm grateful to everyone who supports!

btw, from top to bottom, mnt Kilimandjaro, is the, highest, mountain, in the world, you knew that?
is your clock broken? im so used to looking at it and doing the time from it just because i love your clock
@@jessevanes1Moana Loa is
dude took the wife :P U go girl
I've also heard that the weight of an object at sea level lets say 5lb will get (now this bit I can remember correctly) lighter or heavier at various heights.
Watching the pulse ox was more interesting than the water. I was surprised how early on you were at 90. Also surprised you kept your composure through to the end like this is a thing you do all the time!
I was equally shocked, the 70% would have been scary if it were not for pulse ox being horrible on cold extremities.
Boiling water is like the OPPOSITE of laminar flow. Is Destin ok?!?
Must be the lack of oxygen.
@@smartereveryday😂😊
Haha
Wait until Destin learns about " Laminar flow boiling of water in microchannel".
@@smartereverydaynot enough pressure
Seeing those sudden biome shifts is my favorite thing about mountain hikes
epic
Ok
Those are some real high-level zones
You should check out Atlas Pro's "Islands that aren't actually islands" series if you haven't. Mountains are often ecological islands so they can have a lot of really interesting biology!
When the tree lined is super well definied, stepping past it feels like another world.
Bro just causally has friends in space to take pictures of him doing cool things on earth.
Legend status: confirmed.
Definetly a flex worth having
I don't think it was a collaboration, I think it was just happenstance
The porters are amazing humans. I wish I could post photos of them here. They carried everything and the toilet seat too and had energy to spare. I was dyyying when I got to Barafu camp
I'm proud to be a tanzanian citizen your welcome smart everyday
It's a beautiful country, I used to live in Mwanga (near Moshi).
Your country is beautiful
My father and mother are from kilimanjaro a place called mwika
Bearded Destin? I'm here for it.
I originally thought it was a random video pushed to my feed and dismissed it, but watched it later from my notifications.
The science is why I started watching your videos. The amazing people you interact with are the reason I keep watching them. Thanks for your fantastic videos!
I live at 4000' and recently purchased an electric tea kettle. It has a setting where it's supposed to heat the water to 212° F then beep and shut off. It boils but never reaches 212° and doesn't shut off.
oh wow! I've never thought of that! And apparently the person that designed that didn't either!
I live a little over 6,000' and have the same issue, so invested in an electric kettle with different temperature settings. I normally use the 190 setting.
If I remember correctly (and I don't have time to look it up right now), @TechnologyConnections did a video on a relatively cheap & simple, electric kettle design that detects boiling regardless of temperature. Might be worth looking into.
@@riuphane that's strange, usually electric kettles switch off when the liquid starts to boil and not when it reaches a specific temperature, Steve mould has a video on this.
@@AdmiralThumbsYup, remember that video. Ironic that modern kettles are more likely to boil dry
Love this guide. Knows his stuff and knows it well
Shedrack is awesome.
You sounded a little drunk right before you left the summit 😜
Oh yeah, "I Appreciate your Leadership" line felt drunk. Mix of exhilaration, awe, and light hypoxia probably did that.
Thank you Destin, for bringing us along. I know I am no where in the shape needed to summit Mt Kilimanjaro but you brought me (us) along as if we were in your pocket, and for that I am grateful to have been there through your experience.
Please don't get the summit bug and attempt Everest. It's way to dangerous and would hate to see anything happen to you.
No technical climbing for me.
As the legendary altitude sickness expert Dr Peter Hackett once said "there are three treatment options for altitude sickness: descent, descent and descent".
3:02 is it fun to be a porter? As the ladies walk by with 50 kilos on their heads... 😅
You can truthfully say: "My science has reached new heights!"
Great to see you "stepping up" your game! :D
I absolutely love the attitude of the KiliWarrior staff! Keeping the mindset of slow and steady wins the race but also having fun while doing it! They’re really people’s people and I hope one day I’ll be fit enough to meet them 😊
Thank you everyone for this splendid piece of scientific art; all your efforts culminated in a top-notch watch ❤
I've been waiting for this since listening to the "songs of the ascent" episode on No Dumb Questions. You paint such a great picture during the podcast but I'm glad to see some of it in the video. Keep it up Paparazzi!
I loved the NDQ episode and fully agree
At 8:30 couldn't it just be a weather change? Maybe a high (higher) pressure system was moving through
Really great you experienced this with your wife. Very special woman. Great video, the blood O2 info was fascinating, wish you shared more of the readings.
I've been waiting for this episode since the "Songs of Ascent" NDQ episode! I can't wait to watch it when I get a break from work!
"They're asking why paparazzi isn't being paparazzi" that's great.
Been waiting for this since Songs of Ascent!!
Would be cool if u could do a short text at the bottom or something of the units converted to metric.
This isn't a criticism, just an odd observation:
Weird that they're using imperial altitude measures but metric temperature. The temp makes sense for this context, even though I believe Fahrenheit is more intuitive for daily life. So similarly, it would have been interesting to see F° temps on-screen as well.
For most cases, divide by 3 will get you close. It is over by like 10%, so take off another 10%. If you want to be closer add back in 10% of that to be off by less than a percent and half more to be around a thou. 18000 ft /3 -> 6km -10%(600m) -> 5.4km + 60m ~> 5460m
Real conversion 18k => 5486m
Error (5486 - 5460) / 5486 => under by 0.47%
Error (5486 - 5490) / 5486 => over by 0.072%
I remember it as 3,10,10. Reverse it to go from meters to feet. Both are easy to do in the head and rare in the real world situations that being off by a few percent isn't going to be rounded off anyways.
Reversed: 6km x3 -> 18k + 10% (1.8k) -> 19.8k - (180) ~> 19,620 ft is short of 19,685 ft by 0.3%
Pole pole, paparazzi
Congratulations on conquering the Kilimanjaro, epic photo`s as usual. a well earned rest for all of you after that. And great initiative from IMI...
I love your reference to Psalm 95 at the end, Destin. Your videos are incredibly thoughtful and I loved experiencing both the NDQ and SED content on this experience. I love how you tie in biblical themes like "songs of ascent" and Psalm 95:4, etc. A blessing to watch your content as you point others to Christ. "The earth is the Lord's and the fullness thereof, the world and all those who dwell therein" (psalm 24:1). Much love brotha
ah i guess i never realized that, at these elevations where the boiling point is lower, the water will never reach a temp higher than that boiling point. im not sure why but i never thought about it, i thought the water itself could continue to get hotter. maybe it can via steam or some sort of superheating. but just normal boiling it doesnt raise above the boiling point (sounds so obvious saying it aloud haha)
Yes! It's because changing state from liquid to gas is an endothermic reaction, it takes energy to do. So every gas bubble that's created reduces the heat energy by just a little bit, and the temperature balances itself at the boiling point. If you turn up the flame and add more heat, that only makes it boil more violently, but the temperature will never go higher than the boiling point. But you can get hotter liquid water by heating it in a sealed pressure vessel, because boiling point increases as the pressure builds.
Boiling means turning to gas. That cools since it takes energy away. Same happens to your skin when your sweat evaporates.
It is a heat transfer mechanism.
If it didn't the world as we know it would not exist.
Wasee amkeni! Kuna mzungu ameguza mlima!!! Oh wait... Wrong mountain. Carry on!
we mzee 😂
Listened to the ndq podcast about your climb yesterday, was looking forward to this episode!
Same!
Loved the NDQ podcast on this journey! Very cool.
Congrats! summited 10 years ago. I'll never forget my time at 19,341. Almost "high"... euphoric at minimum. Commendable to keep focused and still boil the water up there. No one will understand how hard that is, or where your mental state was being slightly out of your mind, happy, and trying to do the science at the same time. Respect.
You've summited one of the highest mountains of a continent in a "collab" with Brady, you've worked with Derek on the Coriolis effect using that kid's pool experiment... You guys are awesome, my favorite content creators!
Hey I hiked Kili in 2022. Amazing experience. I hope you got to stop by Amboseli NP at the base of Kili on the Kenyan side! There’s a great view from that park
This is super cool. That was probably a remarkably tiring journey, so thank you for taking it on! :)
So basically if you go high enough you can stick your hand in boiling water without burning yourself?
Small world. Your guide was wearing a SIUE beanie. That’s where I did my undergrad.
Please put an on-screen overlay over the "feet" measurments. It is so unintuitive for the rest of the world.
If you boil water to purify/kill bacteria does that not happen at high elevations? What is the minimum temperature to kill bacteria?
Would a pressure cooker help or does the pressure not build high enough?
That's a great question! I'd wager it's probably still going to kill the bacteria since their internal water will boil
You can just boil longer. There's the thermal death curve where to kill a certain number of bacteria you cook for a specific time and the time changes as temperature changes.
Ooh, very good question! Hope we have some physicists or microbiologists in the comments who can weigh in and tell us.
Edit: just looked it up. Apparently, the biochemistry involved is related only to temperature, not to the phase transition of boiling. That's just a helpful marker for us to see. The reactions that kill the bacteria (denaturing the proteins and such) start at much lower temperatures, like 45C, they just take longer. (Which is why low-and-slow cooking like barbecue works.)
So, you just have to boil for longer. The CDC recommends boiling for 1 minute, unless you're above 6500ft, in which case it's for 3 minutes.
@@will6699But I imagine there is a temperature low enough where that wouldn’t happen. Granted he only got into the 170’s F and I doubt anyone would be at that altitude without clear knowledge of purification of water.
Found an answer (on Reddit so somewhat questionable). 150F/65C for 5 minutes should do it if you’re on top of Mt. Everest.
Anything below that is questionable for some organisms.
❤❤ welcome Africa......love you so much guys........
Yes I’ve been looking forward to this one after hearing the podcast
Only complaint... you should have kept the beard.
Those photos of Kilimanjaro from space are incredible!!
Big congrats to you both!!! Epic achievement +10
What an awesome trek. From afar, it looks like a simple walk.
Small caption correction. At 10:34 someone says "Is your hand cold?" Not "Is your ankle?"
Cold hands can throw off the pulse ox reading as less blood flows through our hands to help conserve body heat in cold weather.
I've always liked that in your videos, you convert the US imperial units into metric system. It would have been nice if you had done so in this video as well...
We are measuring temperatures in Celsius and altitude in feet so that no-one is happy (on screen conversions would be nice)
Otherwise, as always, it's a really nice video
I showed my kids this video, 11yo and 7yo. They didn't believe it, so I got a vacuum pump out and showed them that when the pressure drops low enough, you can get water to boil at room temperature. It blew their little minds 😂
I am surprised by how clean the summit is compared to Everest. Everyone is collecting after themselves.
This was super cool and fun to see. Thank you not only for sharing the experience and science, but sharing the people.
Water boils at 100, ice freezes at 0.
I call shenanigans! :D
Cool guide you've got there 😎
What I find crazy is solar panels and a CCTV camera are up there 🤣
Yeah, on safari on the Serengeti we had internet and wifi in the camp. Blew my mind.
Welcome to kilimanjaro, Tanzania🇹🇿 Destin
Can you do a video on antigravity?
He's looking American with the beard.
Everybody criticizes Fahrenheit without knowing it's origins. It was designed for easy reproduction, not high accuracy. 0F is the temperature you get when you melt ice using salt. 100F is human body temperature (which is remarkably consistent). These can be replicated very easily all over the world, allowing you to make a "pretty good" thermometer.
Achieving 0C and 100C without other advanced technologies (refrigeration, pressure gages) is actually quite hard, as we see here.
All measurement systems are equally as accurate.
I dont fully understand why its boiling at cooler temperatures as the altitude increases, but I'd still like to give it a shot!
As you go up in atmosphere, the air pressure decreases, and because of this decrease, there is less force being exerted on the water (air pressure not gravity) and therefore is able to boil easier because off-gassing is easier. I suspect that a puddle of Isopropyl alcohol would disappear and evaporate at a much faster rate than at sea level using the same logic, less force being exerted on it from all side, making it want to evaporate much faster and at lower temperatures.
Please correct me if im wrong, I really enjoy this type of applied physics stuff though, really gets my noodle moving in a good direction
"air pressure not gravity" Air pressure is the weight (caused by gravity) of the atmosphere above. Less atmosphere above = less weight.
should of 'shaved' it for Movember.
I’m glad I signed up for the email alert. RUclips didn’t tell me a new vid dropped
Thanks for doing that!

That guides are absolute Gs.
Well done! Big achievement!
Just been in the andes awesome video
ft and Celsius... slowly... but surely... slowly... but surely... and they won't even notice that they'll start buying cars that show l/100km and not mpg
😂
SmarterEveryDay is getting DumberEveryDay. Now it's just military recruitment videos and elementary school physics...
Destin, I really hate to admit this, but if I am anything, it is truthful.. But what impressed me most about this video is that you took your wife with you on this epic journey. (Or is it that she took you..? 🤔 😁)
Is this is why coffee sucks in Denver Colorado?
Is this why everything sucks in Denver Colorado?
They hit Homer's though!
🤣🤣🤣🤣
I laughed so loud at the last few lines of banter with your wife in the tent at the end....
Yeah,..... I shan't be climbing all that... I went down the Niabtera river in NW NEBRASKA several years ago... Never again....
I read "Why am I Boiling Water on Kilimanjaro?"
I think "Probably because pressure, change, science, wOoOo"
I click
I noticed your guide had ski cap from SIU-C! Great school, my daughter and I went to their Edwardsville, IL location (SIU-E). Wonderful video Destin. Appreciate you and your channel. Keep making great content.
Wow.. highest mountain in Oregon I work was 5270.. Red Butte . Communications..
The highest I've been outside an aircraft is a little over 13,000ft (3.96Km) on Wheeler Peak, Great Basin National Park, Nevada, USA. This was in my 20's and I thought I was going to pass out.
Tried it again earlier this year and made it a couple of miles before I knew it was a fail. I'll turn 62 at the end of October.
IMI sounds awesome, I think they should have a RUclips compilation/playlist. Basically build a library of videos that are worthy of watching.
Destin, you’re the best. The grace and thoughtfulness with which you deal with all the people you meet along your many journeys is truly inspiring. Great work.
I was in Colorado and 13000ft kicked my butt‼️ As usual you rock ‼️ God bless you for sharing this experience 🙏🙏
Some of the most dangerous words ever uttered: "It's a great thing to have done." Been there a number of times, too. Variations:
"If we get through this part, then we'll know we're good."
"This will be one to tell future generations."
"We're about to find out if we're as good as we think we are."
"This will be an experience that very few have been able to report back about."
"Well, I don't think we can count on rescue/extraction from this, so we'd better make it work."
"I think we can do it. Hopefully the boat can do it, too."
...and the worst of all, because you know you really, REALLY shouldn't be there in the first place:
"Wow, I'll bet almost no one has ever seen something like this before."
I walked up Kilimanjaro in 1969. Thanks for the return trip. There was much more snow then. Lived in Taveta, Kenya as a Peace Corps Volunteer at the time. Thank You
???? Try this and show why so many flowers and bugs up on top... On mountain top , use hand to block sun and look just to side of hand. Spiders by the ton floating, seeds "wishes ", hummingbirds, dragon Flys, " truly the sky's alive.
Great stuff - but no word about the ambient temperature along path. Obviously chilly at the top - but how chilly? (I'd even accept 'F)?
Holy máck, that you managed to get all that, in a 25 min video, were we could still feel the adventure, y’all hard work and some science…that counts for something!
Thank you. Beautiful video.
Cheers
Stupid question…. We can kill bacteria in regular boiling water at 100 degrees. Does the bacteria survive in boiling water that doesn’t reach a 100 degrees?
My mom, who worked in radiology and diagnostic imaging for cancer patients, once told me about how her company was looking into new technology for some process. I couldn't tell you what it was specifically. But it was developed by some third party, and then they sent it over. And her people just couldn't reproduce it. It didn't work.
Turned out that the process relied on boiling water (or, rather, not boiling it) around 100°C, but it was developed on the east coast, and my mom worked in Denver. The difference in boiling point was enough to ruin the process and it had to go back to development.
Perhaps the science in this video isn't flashy. But it's still important.
Re: being thoughtful about my next watch.
I've got a D&D podcast, True Facts about Jellyfish by Ze Frank, American Reacts to 101 Things They Love About The UK!, and We Try Candy From Every Decade! from one of the React channels queued up. All offering interesting insights. Not all the most intellectually uplifting but at least not necessarily mindless or sensationalist. That'll be most of all I watch today. Wanna try and stay of YT Shorts.
The people of Africa are seriously some of the nicest people in the world. When I went to South Africa EVERYONE was super nice
I am glad being subscribed to your channel...for various reasons....one of the newest one being what you expressed in this video - the need and urge to "fight" against existing algorhytms and try to push better content in various ways, one being this time the Independent Media Initiative....you make people watching your videos more knowledgeable and fact educated....just what is so desperately needed in this "cheap content" era (not to mention "alternative reality")....excellent work...and respect to those kiliwarriors guys and gals.....such an enlightening insight.........❤
Absolutely one of your best videos so far. As always educational, honest, qurious and with a very personal twist.
Keep up the good work Destin

13:36 TWSS 😅
Jokes aside, I loved everything about this video, Destin, and really appreciate you sharing your journey with us, especially your highlighting all the amazing, hard-working, conscientious people that made it possible. Through efforts like yours, "pole" we all come together ❤
Hi Destin. What you say about seeing somewhere special where you have been from space makes it somehow even more special. Amazing.
I can't believe it's been 10 years since Brady's video. Feels like 1-2 years ago. Btw, fantastic work on the video. I will keep the next video I watch in mind! 🙂
My next video is more Destin. You bet I'm clicking it! Thats me being very critical of what I watch. SNATCH LOCK
Hey, it's me, Destin. Today I'm going to show you how to make your vacation tax-deductible by boiling water xD
Thoughtfulness, that's exactly why I'm always excited to watch your videos regardless of the subject. Keep up the great work!
Just an interesting fact, most airlines only pressurize to the pressure 16K feet ASL. So, it's like hanging out at 16K feet for hours. Mind you, your not climbing and doing the same amount of work, but yeah most people don't know that.
Destin, Have you seen the laminar flow rocket engine that Integza is building??
Because I've never seen anything that screamed "Destin would LOVE this" more, lol
Destin, I was in the Navy a very long time ago and had the opportunity to see Kilimanjaro for myself. Of all my travels, I would love to go back and see that beautiful, majestic sight once again!
I once had altitude sickness at 12k ft. 19,000ft is amazing. Much harder than most understand. Good Work!!
15000ft has the same effect on your blood oxygen as having COPD - a common smoking related lung condition.
Even in hospital we try and keep people between 88-92% saturation because that’s all the body can handle then, but every step is like carrying a heavy pack and walking to the shops becomes a mountain trek of exertion.
Such a beautiful verse to end the video Psalm 95:4 - In his hand are the depths of the earth, and the mountain peaks belong to him.
