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.
I know it wasn't the focus of the video, but I really appreciate the effort you made to highlight the porters and the locals that were helping you along. The section right around 5:50 with the porters singing in the background was just so fun to watch and experience.
I climbed via the Lemosho route in 2013 and the porters and guides were a huge part of what made it so much fun! Such a cool group of people for such a cool experience 😊
Not to be a hater but watching the porters and then seeing destin with not even a standard back packing pack, was a bit disappointing. I understand he is probably not up to the requirements to do such a trip with such a load. I just felt physical pain for their necks and would not be able to stand by why they lifted 6x my load.
The “locals helping him along” are highly skilled guides with knowledge of terrain, biology, medical treatment, leadership skills, weather and climate.
@@bigmandy841 It's their job. If people tried to carry all their own stuff, 1. It would more dangerous by far, 2. They wouldn't have as many porter jobs to help the locals, and 3. The porters DON'T want you carrying your stuff for those reasons.
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!
My initial thought was, poor guide needs to professionally play along with the tourist's antics, and then he turned into a passionate co-host. Not much rocket science here, but a pleasure to watch. Thanks!
Hey Destin - I very rarely comment on internet things, but have been watching for years. I finished this video last night and came back to say how much both this AND the podcast episode on this journey impacted me. The stuff you make is that amazing middle ground between the "teachable" and the "beautiful." Long way to say - thanks for the internet a better place to be and for the ridiculous sticker of a certain fictional Greek on my laptop. I thought your photography was a HUGE addition to this video as well. Thanks!
I have been watching Destin for years and years now, and one of the things that always, ALWAYS impresses me is how he very intentionally learns peoples names. He is a genuinely caring person who makes people feel known and noticed just through simple, kind interactions. I strive to be more like this. Not just Smarter Every Day, but better every day, too.
I hadn't noticed this aspect before, but it helps explain why he stands out among sciencetubers. He's a decent man, who cares for people. Might be the simplest form of nobility.
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.
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.
"Thank you for your leadership". What an important concept when tackling a difficult project whether summiting a mountain or creating a fantastic TH-cam channel. So many of your videos exemplify leadership by your subjects. It is a theme that deserves to be called out more often!

@@NibblyBitz Yeah, below a certain PI, the pulse-ox numbers aren't really reliable. Most inexpensive pulse-ox devices don't directly tell you the PI, although some will if you connect via bluetooth and a phone app.

This was such an amazing video! Loved the production quality, the raw presence of being there, the audio capturing the calm of the porters and guides. Amazing! So glad I clicked on this video.
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.
Reminds me of a report I saw somewhere about electron microscopes that didn't work at a fairly high altitude. The manufacturer had not tested under low pressure conditions.
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 feel like I have lost so many channels I once loved to this algorithm chasing. This channel aint one of those. So glad you have stayed the same all these years making quality thoughtful content.
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 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!
That was something I loved about the podcast, the way he conveyed the emotions of what was going on as he went up the mountain and having Matt there to discuss and ask all the questions that we were all wanting to ask as well was fantastic. I love his nickname paparazzi so much, it is so fitting. Him explaining what was happening to the altitude sickness man was intense but the picture of the tour guide painted such a strong leader in my head. One of his best podcasts I reckon.
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.
I thoroughly enjoyed this video! I was locking in the whole time. The music, Shadrack's charismatic professionalism, the scientific measurements, the interactions with your wife, the pacing, giving credit to those who inspired you, and even the sponsor. Thank your Destin for your work and I wish you the best!
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 😂
Shout out for the music in this video! It underlined the adventurous character of the trip, and some good old Shell In The Pit at the end made it perfect. Thank you for the thoughtful content you're creating!
As the legendary altitude sickness expert Dr Peter Hackett once said "there are three treatment options for altitude sickness: descent, descent and descent".
I remember going down a 45° gravel slope in six foot steps because one of the group members got altitude sickness pretty bad. There was just one guide and three group members remaining at that point, so we had to stay together. Boy were we down quickly. It's a weird thing, because you can never really get used to it. Even the guides that went up dozens of times sometimes still get it.
I haven't climbed Everest, but I assume it's "dirty" cause people want to leave their mark at the highest point in the walkable world. Not a good excuse though. The other reason is probably cause you can die very easily; meaning you can leave an ox cylinder cause you are about to die and got to gtfo.
@@HansMaximum It's also dirty because the such steeper slope makes it near impossible to safely collect garbage or even bodies in some area, Kilimanjaro looks like it has gentler inclinations, making it easier to go and collect garbage. There might also be a lot less tourists climbing, Everest has become a conveyor belt, it's so over frequented at this point.
There's a cool video of the latest purpose-built DJI Drone that's able to fly up over the Khumba Icefall in 10 minutes (normally a day's dangerous hiking/climbing) and return in 10 minutes with 4kg of rubbish (mainly discarded oxygen bottles). It's a massive step change in the Sherpas' ability to clean up the mountain cheaply, safely and quickly.
i’ve watched you since i was a child and you’re videos have always had a low level of accessibility i feel most education channels lack you can tell you have a genuine love for humanity and knowledge
18:20 This is a super important point. Doesn't matter what you're doing, doesn't matter your athleticism. You need to be cognizant of your heart rate, your target heart rate and the trend over time. Time. Don't care if you're walking up a hill or Kilimanjaro or moving bricks in the yard. You can't run your body at redline like that, especially as you get older.
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!
This entire video just made me so happy. The beautiful singing sequences, the scenery, and the whole idea behind the IMI. Love your channel man, I'm so glad I got to see you when you came and spoke at my university in 2014!
I did the northern route a few months ago and this video brought back so many memories! All the porters and guides are amazing. I like how the video isn't about how tough Destin is to have submitted but you could have given yourself a bigger pat on the back, summit day is brutal! Well done and as always amazing video!
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 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 ❤
It's good to a*have you on the platform Destin! Having access to so much interesting content is what keeps me curious everyday and what made me learn english without even thinking of it
Loved the video. I haven't finished watching yet but I had stop and thank you for introducing me to IMI. I haven't even checked out the website yet but I recognized a lot of the other TH-camrs I watch amongst the promo clips you showed and I'm excited! I'm struggling with the TH-cam algorithm to find interesting and thoughtful content in the midst of all the content that's promoted to me, some of which I think is more about what TH-cam wants me to see than what i want to see. Having a new source is great!
My wife and I did the Machame route in 2014. What an experience! Destin, your video brought back so many memories - smells, sights, flora, and the vibe of the porters and guides - thank you!
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.
A similar thing happens with melting ice. When you add heat, it turns from 0C ice to 0C water. But ice can't exist at higher than 0C (at room pressure). This is why a mix of ice and water, and I believe water and steam, can be used as a reliable temperature reference (except for the pressure thing ;P)
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.
Now that we've been back and forth, I've come to the conclusion, that Destin understands his audience very well. We prefer titles and thumbnails with added beard, and yet, he does not over-do it with extreme words like "mustache", which could scare off potential subscribers. Perfectly balanced. Edit: Wait... What are you doing. Where has the beard gone?
I love that you are able to take the information that brady learned from his experiment and build upon it for a well-rounded understanding of the topic. This is one of my favorite TH-cam channels
This was awesome to see! When i did my Everest Base Camp trek i closed a empty water bottle at 5400 meters. it was so cool to see it get crushed slowly whilst i took it down the mountain. i kept it untill i got home (the Netherlands) wich is probably as low as you can go in terms of altitude. The bottle was really crushed by that moment. i Love it when you can combine 2 very different things you love in a single moment.
Great work Destin. My kids always ask me to check if there's a new video from you. You're making science, discovery, and curiosity fun for them and I can't say how much I value that.
Congratulations on your summit of Kilimanjaro. Being 78 with moderate COPD such an adventure is beyond my physical abilities. I can drive my oximeter reading from 95 to 70 in less than five minutes at 500 feet; no way I could make it at altitude.
The thing I enjoy most of all from your content is that you take the time to show your thanks to the people who help you along the way. We only see you through these little screens but it says a lot that you make sure to keep the humility and gratitude visible. It’s a small reminder ya know.
How did you do the visualization of the GPS track in Google Earth? I tried something like this in Google Earth Studio and export frame images from there, but the track is always flickering, meaning there are some frames, where the track isn't visible. Yours looked really good you even got the temperatur points added.
25:16 people don’t understand the downhill is more rough because you are not used to that type of physical exertion. You think it’s the same as stepping up when you do your workout. It isn’t.
Hey Destin, still watching but just wanted to say your NDQ episode about this climb has got to be one of my favorites ever. really inspiring hearing about the amazing people you had surrounding you. What a life changing experience.
I love the photography, the story telling, the music, the edition, the knowledge and experience sharing, the couple, the journey, your gratitude and commitment, I love everything about this video Destin. Congratulations and thank you! You are a legend and a big inspiration dude, thank you! 🎉🎉
Hey Justin, hiking the Kilimanjaro is on my bucket list for 5 years now, and next year I’m going. Six month ago I went through a bariatric surgery, and my end goal is to hike the mountain. Since I decided to do through all of this I’ve been looking for information all weeks about the hiking and your video is by far the best content that I have seen. Thanks for taking the time and sharing this amazing experience with all of us. I was looking for some porters but now I’m going to use Kiliwarriors.
your appreciation and dedication to making sure that what we watch is entertaining and intelligent brought tears to my eyes, keep being awsome, you're killing it.
Destin talks about that in more depth in the NDQ podcast. Bottom line: it's hard work, but because of the teamwork and camaraderie, as well as the genuine love for people, there is joy in it as well.
Destin, I always enjoy your videos, informative and entertaining. This one is somewhat personal to me as I noted this phenomena when I moved from Orange County California (Essentially sea level) to Castle Rock, CO (just over 6,500 feet) My tea pot would not turn off when set to 200 degrees, but the water was boiling. Turns out water's boiling point at this elevation is about 199.6 degrees. This also points out the fallacy of the Celsius' metric being freeze at 0 degrees and boil at 100 degrees. Only true if you are at sea level.
Destin, I love you little mini interview with your wife at the end. A little real moment that rings so true for those that have done journeys like this. Thanks for the great video.
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%
@@AdmiralThumbs I imagine the guides know altitudes in both metres and feet to be able to speak to both American and other tourists. For Destin, preferring feet and °C might be a reality of engineering in North America-as an example, I do design engineering in Canada, and for American suppliers, I would almost always expect thermal specifications in °C but dimensional measurements most often in inches. I've noticed that many manufacturers clearly design in mm but then have their reference and manufacturing drawings specify inches. Aviation has some similar chimeric unit situations: pretty much everywhere other than former Soviet states use feet and knots, given the US's influence in early aviation. However, in Canada and Europe we use °C for temperatures; and in Canada, we use inHg for pressure like in the US, whereas in Europe they use mbar/hPa.
@@sanholo9494 RE: @barongerhardt and @Laogeodritt both state good points. For an educational video, I was just thinking it'd be useful to communicate both systems of measurement (on screen; no need to bother the guide with this in the moment) to help the most people relate to the units they're familiar with. As a side benefit, things like this could help more Americans get comfortable with the metric system.
Seeing Blacktail Studio at the beginning of the IMI ad blew my mind. I don't watch that many channels and I don't add subscriptions very often. I've been watching you and Cam for years. I guess I watch thoughtful creators that make quality content. thanks
Thank you for the amazing and enlightening video, Mr Destin. Your interaction with the guide and porter are truly beautiful. Cannot wait the extra video on the second channel, and definitely will listen to the podcast.

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.
I thoroughly enjoyed this video! I was locking in the whole time. The music, Shadrack's charismatic professionalism, the scientific measurements, the interactions with your wife, the pacing, giving credit to those who inspired you, and even the sponsor. Thank your Destin for your work and I wish you the best!
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 😂
It can be used the other way around too; pressure cookers can go to higher temperatures, and cook food faster.
Yet again Destin shows that film photos capture so much more emotion. Beautiful video!
Shout out for the music in this video!
It underlined the adventurous character of the trip, and some good old Shell In The Pit at the end made it perfect.
Thank you for the thoughtful content you're creating!
As the legendary altitude sickness expert Dr Peter Hackett once said "there are three treatment options for altitude sickness: descent, descent and descent".
Descend a bit, take it easy, wait.
I remember going down a 45° gravel slope in six foot steps because one of the group members got altitude sickness pretty bad. There was just one guide and three group members remaining at that point, so we had to stay together. Boy were we down quickly.
It's a weird thing, because you can never really get used to it. Even the guides that went up dozens of times sometimes still get it.
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.
I bet those forklift drivers sound like this all the time.
They might need a little extra O2
90% oxygen before even getting moving and going higher thats wild
“Rate your summit” 10/10
@@brandonbradford2733 I half expected him to say "I love you" after that
I am surprised by how clean the summit is compared to Everest. Everyone is collecting after themselves.
I haven't climbed Everest, but I assume it's "dirty" cause people want to leave their mark at the highest point in the walkable world. Not a good excuse though. The other reason is probably cause you can die very easily; meaning you can leave an ox cylinder cause you are about to die and got to gtfo.
Garbage. Don't pack out
@@HansMaximum Base camp on Everest is basically a landfill. Its disgusting.
@@HansMaximum It's also dirty because the such steeper slope makes it near impossible to safely collect garbage or even bodies in some area, Kilimanjaro looks like it has gentler inclinations, making it easier to go and collect garbage. There might also be a lot less tourists climbing, Everest has become a conveyor belt, it's so over frequented at this point.
There's a cool video of the latest purpose-built DJI Drone that's able to fly up over the Khumba Icefall in 10 minutes (normally a day's dangerous hiking/climbing) and return in 10 minutes with 4kg of rubbish (mainly discarded oxygen bottles). It's a massive step change in the Sherpas' ability to clean up the mountain cheaply, safely and quickly.
i’ve watched you since i was a child and you’re videos have always had a low level of accessibility i feel most education channels lack you can tell you have a genuine love for humanity and knowledge
18:20 This is a super important point. Doesn't matter what you're doing, doesn't matter your athleticism. You need to be cognizant of your heart rate, your target heart rate and the trend over time. Time. Don't care if you're walking up a hill or Kilimanjaro or moving bricks in the yard. You can't run your body at redline like that, especially as you get older.
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!
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.
Bloody Oath! Suits him epically!
Beautiful video!
Did not expect to see Alec Steele here.
This entire video just made me so happy. The beautiful singing sequences, the scenery, and the whole idea behind the IMI. Love your channel man, I'm so glad I got to see you when you came and spoke at my university in 2014!
I did the northern route a few months ago and this video brought back so many memories! All the porters and guides are amazing. I like how the video isn't about how tough Destin is to have submitted but you could have given yourself a bigger pat on the back, summit day is brutal! Well done and as always amazing video!
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 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 guess many of us could learn a lot from them.
"They're asking why paparazzi isn't being paparazzi" that's great.
On day two, they named me paparazzi because of how often I had a camera out.
It's good to a*have you on the platform Destin! Having access to so much interesting content is what keeps me curious everyday and what made me learn english without even thinking of it
Loved the video. I haven't finished watching yet but I had stop and thank you for introducing me to IMI. I haven't even checked out the website yet but I recognized a lot of the other TH-camrs I watch amongst the promo clips you showed and I'm excited! I'm struggling with the TH-cam algorithm to find interesting and thoughtful content in the midst of all the content that's promoted to me, some of which I think is more about what TH-cam wants me to see than what i want to see. Having a new source is great!
You can truthfully say: "My science has reached new heights!"
Great to see you "stepping up" your game! :D
Been waiting for this since Songs of Ascent!!
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!
My wife and I did the Machame route in 2014. What an experience! Destin, your video brought back so many memories - smells, sights, flora, and the vibe of the porters and guides - thank you!
This has inspired me to climb this mountain. I will do so by 2026 at this time.
Thank you, Destin.
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.
A similar thing happens with melting ice. When you add heat, it turns from 0C ice to 0C water. But ice can't exist at higher than 0C (at room pressure). This is why a mix of ice and water, and I believe water and steam, can be used as a reliable temperature reference (except for the pressure thing ;P)
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.
Destin's brain was on MS-DOS at those higher elevations. Quite a sight to see. Also!, Great sponsor. I'm going to watch another Smarter Every Day!!!
Now that we've been back and forth, I've come to the conclusion, that Destin understands his audience very well. We prefer titles and thumbnails with added beard, and yet, he does not over-do it with extreme words like "mustache", which could scare off potential subscribers. Perfectly balanced.
Edit: Wait... What are you doing. Where has the beard gone?
LOL. Believe it or not this one performs better?
This video was amazing! I was glued the whole time. The scenes of being above the mountain, above the clouds, its so magical
At 8:30 couldn't it just be a weather change? Maybe a high (higher) pressure system was moving through
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...
Listened to the ndq podcast about your climb yesterday, was looking forward to this episode!
Same!
I love that you are able to take the information that brady learned from his experiment and build upon it for a well-rounded understanding of the topic. This is one of my favorite TH-cam channels
I remember Brady’s video and having the same feeling. So simple but so clear. And what a beautiful place to film a video.
Big congrats to you both!!! Epic achievement +10
Yes I’ve been looking forward to this one after hearing the podcast
This was awesome to see!
When i did my Everest Base Camp trek i closed a empty water bottle at 5400 meters. it was so cool to see it get crushed slowly whilst i took it down the mountain. i kept it untill i got home (the Netherlands) wich is probably as low as you can go in terms of altitude. The bottle was really crushed by that moment.
i Love it when you can combine 2 very different things you love in a single moment.
It's nice to see Tara so well, you two are so lovely to watch together.
Great work Destin. My kids always ask me to check if there's a new video from you. You're making science, discovery, and curiosity fun for them and I can't say how much I value that.
Those Kiliwarrior folks are beyond amazing. Prime examples of the resilience that humans are capable of.
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.
Aconcagua?
Chimborazo is better. Plus there is a great flood story there too.
@maggru91 Says the neckbeard from his mom's couch
"We're going to climb both peaks of Kilimanjaro....."
My immediate association whenever that mountain is mentioned
Wonderful video Destin, thank you to the guide & porters of Kilimanjaro for making sure you got there & back safely.
we need more media like this! thanks so much for maintaining your integrity in making awesome content for us to learn, explore, and enjoy life!
How to write off your vacation while cleverly disguising it as a scientific experiment.
I think that is what he meant by stealing Brady’s idea
Evading taxes 101
I hope so! If I could write-off spending time with a woman I loved and sharing the story with hundreds of thousands of people. I sure as heck would.
11:05 hahahah pick the best number!!!
Cool guide you've got there 😎
Congratulations on your summit of Kilimanjaro. Being 78 with moderate COPD such an adventure is beyond my physical abilities. I can drive my oximeter reading from 95 to 70 in less than five minutes at 500 feet; no way I could make it at altitude.
The thing I enjoy most of all from your content is that you take the time to show your thanks to the people who help you along the way. We only see you through these little screens but it says a lot that you make sure to keep the humility and gratitude visible. It’s a small reminder ya know.
How did you do the visualization of the GPS track in Google Earth? I tried something like this in Google Earth Studio and export frame images from there, but the track is always flickering, meaning there are some frames, where the track isn't visible. Yours looked really good you even got the temperatur points added.
25:16 people don’t understand the downhill is more rough because you are not used to that type of physical exertion. You think it’s the same as stepping up when you do your workout. It isn’t.
I recall learning that about 80% of accidents happen on the way down [citation needed]
Downhill is so hard on the joints. Especially downhill with weight.
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.
Lowest Starlink latency ever!
Hey Destin, still watching but just wanted to say your NDQ episode about this climb has got to be one of my favorites ever. really inspiring hearing about the amazing people you had surrounding you. What a life changing experience.
I love the photography, the story telling, the music, the edition, the knowledge and experience sharing, the couple, the journey, your gratitude and commitment, I love everything about this video Destin. Congratulations and thank you! You are a legend and a big inspiration dude, thank you! 🎉🎉
6:48 I think it's a fish
"To check we'll count the bones, one up top one below, not enough to be a fish, or reptile"
That guides are absolute Gs.
Um... the next video I was planning on watching after this is Ze Frank's True Facts: How Jellyfish Hunt. Am I not supposed to watch that?
I cant think.of a better one....! 😁
no one can answer that but yourself
I watched it before this one.
Hey Justin, hiking the Kilimanjaro is on my bucket list for 5 years now, and next year I’m going. Six month ago I went through a bariatric surgery, and my end goal is to hike the mountain. Since I decided to do through all of this I’ve been looking for information all weeks about the hiking and your video is by far the best content that I have seen.
Thanks for taking the time and sharing this amazing experience with all of us.
I was looking for some porters but now I’m going to use Kiliwarriors.
your appreciation and dedication to making sure that what we watch is entertaining and intelligent brought tears to my eyes, keep being awsome, you're killing it.
So basically if you go high enough you can stick your hand in boiling water without burning yourself?
Yes. The problem is that the water in your hand would be close to boiling, too. Which could be harmful in other ways.
Put water in a clear syringe and cover the needle end. Retract syringe until under a vacuum and watch the water boil at room temp.
3:02 is it fun to be a porter? As the ladies walk by with 50 kilos on their heads... 😅
The guides and porters have to say that otherwise they might get in trouble with their agency... The chances of them dying while working is not low
One must imagine the Porter happy.
Destin talks about that in more depth in the NDQ podcast. Bottom line: it's hard work, but because of the teamwork and camaraderie, as well as the genuine love for people, there is joy in it as well.
@@ChrisHendricksThanks for creating CP dude!!! Loved that game! (Also thanks for the detailed comment).
Wasee amkeni! Kuna mzungu ameguza mlima!!! Oh wait... Wrong mountain. Carry on!
we mzee 😂
😂😂 mambo imechemka
Destin, I always enjoy your videos, informative and entertaining. This one is somewhat personal to me as I noted this phenomena when I moved from Orange County California (Essentially sea level) to Castle Rock, CO (just over 6,500 feet) My tea pot would not turn off when set to 200 degrees, but the water was boiling. Turns out water's boiling point at this elevation is about 199.6 degrees. This also points out the fallacy of the Celsius' metric being freeze at 0 degrees and boil at 100 degrees. Only true if you are at sea level.
Destin, I love you little mini interview with your wife at the end. A little real moment that rings so true for those that have done journeys like this. Thanks for the great video.
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%
@@AdmiralThumbs I imagine the guides know altitudes in both metres and feet to be able to speak to both American and other tourists. For Destin, preferring feet and °C might be a reality of engineering in North America-as an example, I do design engineering in Canada, and for American suppliers, I would almost always expect thermal specifications in °C but dimensional measurements most often in inches. I've noticed that many manufacturers clearly design in mm but then have their reference and manufacturing drawings specify inches.
Aviation has some similar chimeric unit situations: pretty much everywhere other than former Soviet states use feet and knots, given the US's influence in early aviation. However, in Canada and Europe we use °C for temperatures; and in Canada, we use inHg for pressure like in the US, whereas in Europe they use mbar/hPa.
@@sanholo9494 RE: @barongerhardt and @Laogeodritt both state good points. For an educational video, I was just thinking it'd be useful to communicate both systems of measurement (on screen; no need to bother the guide with this in the moment) to help the most people relate to the units they're familiar with.
As a side benefit, things like this could help more Americans get comfortable with the metric system.
Is this is why coffee sucks in Denver Colorado?
Is this why everything sucks in Denver Colorado?
They hit Homer's though!
Seeing Blacktail Studio at the beginning of the IMI ad blew my mind. I don't watch that many channels and I don't add subscriptions very often. I've been watching you and Cam for years. I guess I watch thoughtful creators that make quality content.
thanks
Thank you for the amazing and enlightening video, Mr Destin. Your interaction with the guide and porter are truly beautiful. Cannot wait the extra video on the second channel, and definitely will listen to the podcast.
Small world. Your guide was wearing a SIUE beanie. That’s where I did my undergrad.
I had to pause the video when I saw that haha just stared at the screen like... Is that an SIUE beanie??? Lol
Likewise! Small world!
Didn't go to SIUE, but lived in St Louis for 8 years. Was not expecting to see an SIUE beanie at the top of Kolimanjaro
Only complaint... you should have kept the beard.
How in the world did someone make a video about boiling water that I WANTED to see?
At 67 years old my mountain climbing days are long past, I always explained to friends that descending the mountain was more difficult than the climbing. I really enjoyed your video. Thank you
Thank you for everything Destin! Always.
