DRINKING NASTY SWAMP WATER (to save the world)

DRINKING NASTY SWAMP WATER (to save the world)


About a year ago, I read about this powder You could add to super muddy water like this, and then you stir it up and five minutes later the mud has separated from the pure clean drinkable water. And as a man of science I see this and it feels like nothing short of magic. I only make 12 videos a year so I am really picky about what topics I will cover and even though I usually just focus on using science and engineering to make to make totally ridiculous things (Motors whirring) (Glass shattering) (Kids screaming) At least once a year, I try to make the case that these same science and engineering principles are also being used to actually change the world for the better. For example last year I met with Madhu Prakash from Stanford who was disappointed to realize the typical microscope and centrifuge to diagnose malaria cost tens of thousands of dollars and needs to be plugged in. So he invented a paper microscope and a paper centrifuge that cost 68 cents that can diagnose malaria and require no electricity. So today we’re gonna find out how this was invented How the heck it works and how it’s being used to help people all around the world But first to demonstrate this isn’t some kind of smoke and mirrors trick I located the nastiest water I could find near my house and met up with some intrepid field scientists. So today I’m joined by my friends Cole, Kaden, Rainy and Max I promised them they could be in a video But I didn’t tell them which one or what we’d be doing. And here’s the deal guys. We need to go into that pond That’s all gross and nasty and fill it up with muddy water. Can you do that? [Excited music] Do you guys think this would be good to drink this? No. What would you guys give me if I take a sip of this umm 20 bucks. 20 bucks? Okay, we’re not gonna do anything to this one, but I’m gonna do something to this one So then we can compare the two. Okay, so I’m gonna take a little bit of this powder I’m gonna put it in here you guys see this and then we’re gonna take turns shaking it for like five minutes, okay (Chill music) ew Let’s see what happens It looks better Okay, I’m gonna put my thumb at the water level so you know I’m not tricking you guys okay Eww (Water swishing) It’s some high quality H2O right there. All right, where’s my 20 bucks Rainy? Mommy
[laughter] Chances are if you’re watching this video you have essentially an endless supply of clean water at The pull of a lever. And because this is so easy, we tend to forget just how critical water is for us You can live three weeks without food but only a few days without water and it’s not just us from plants to ants to bacteria, anything that is biological and living needs water to survive It sounds crazy but there are no exceptions to this rule because of this when NASA is looking for evidence of life outside our planet We first start by looking for evidence of water given all that It’s a total bummer that nearly 1 billion people around the world don’t have access to clean drinking water. Today, drinking contaminated water causes more deaths than HIV, AIDS, and malaria combined And so that’s why the powder in this packet is a really big deal It was invented by a guy named Philip Souter He’s a laundry scientist at Procter & Gamble who was originally trying to figure out a way to separate dirt from used laundry water and I want To be clear here. They are not sponsoring this video in any way I just think what they’re doing is really awesome and they deserve some credit So I was actually able to track Philip down and he told me all about how it works So essentially as three processes there’s coagulation then the next phase is flocculation And then the last piece is the disinfection. You start with clean water like this But now it’s all brown because it’s filled with lots of dirt particles, parasites, and bacteria. So you dump the powder in the water and as Phil explained, the coagulant part of the powder goes to work first It’s basically seed crystals that are positively charged and because the dirt in the water is negatively charged, these seed crystals act like dirt magnets. These dirt magnets grow until they’re each about a millimeter in size. The next part of the powder to activate is the flocculent, which is a polymer which you can think about as having huge long arms that wrap up all the little dirt magnet clumps and now they form bigger chunks as large as a centimeter. These chunks now are so big They’re just slightly more dense than the water, which means they sink to the bottom. and finally, the chlorine is released and it goes to work on killing the 99.9999% of All the really tiny viruses and bacteria that are left in the water that didn’t get wrapped up and sink to the bottom so now you’re just left with safe drinking water at the top. This isn’t just some PR stunt for P&G since 2004, millions of people in over 90 countries have used these packets and they’ve saved untold thousands upon thousands of lives. In fact, they’ve cleaned enough water to fill a swimming pool that is the typical five feet deep by 15 feet across only the length would need to stretch all the way across the United States, over 13 times. These packets cost them pennies to make which they sell at a loss and that feels like the right thing to do, but it brings up the question: Is there a case to be made beyond altruism where it’s in the best interest of the rich countries to help out the poor countries? To answer this question I wanted to speak with someone in the technology sector who had some experience in this kind of thing And he’s a bit of an obscure up-and-comer named Bill Gates But first I had to do a little bit of research in order to get myself up to Seattle [excited music] When I arrived they told me I was free to make myself at home while I waited for him to show up, so I did what any rational person would do given the circumstances, I made the richest man on planet earth some pizza rolls. Hi. Good to meet you. Yeah, thanks for doing this. They gave me free reign of your kitchen and as a token of hospitality, I whipped up a batch of pizza rolls. Oh wow. I’ll try it. It’s not what I normally eat. Its really hot, actually. They’re kind of like lava in the middle. Not bad. They’re ok right? A little bit of cardboard. What do you got here? This is plan B because I wasn’t expecting you to actually eat one of those. Dick’s burgers. Love dick’s. It’s a Seattle phenomena. Truth be told I actually knew this after seeing a picture of him on reddit. He’s standing line by himself to buy one of their hamburgers for less than two bucks. Hate to disappoint you there’s no Dick’s burgers in here. Okay. We have some liquid refreshment That’s pretty dark looking. So I took out the powder and explained to him how it worked and then I set up the bottles, and here’s where we stood after a minute or two. Looks like we’re making some progress on the top there. I’d rather eat these than that so far. Why should we care about developing nations? Well the amount of resource that rich countries spend in helping poor countries is pretty small. It’s well less than 1% of their budget. I defend that because that money is so impactful. You’re saving lives for less than $1,000 per life saved. If you help the country lift itself up then countries like Indonesia, Vietnam, India get successful enough, they grow their economy. So they no longer need aid. They graduate. Okay. Look at this It’s amazing the way that is small, Isn’t it crazy? amount of this thing It’s like magic and I like his answer that basically teaching a man to fish is better than just giving a man a fish. What about the extreme case of a person who’s just super self-absorbed who might think I just don’t care if a poor country has a fish or not, It doesn’t affect my daily life. I asked what he would say to that person. The benefits are strong even if the pure humanitarian empathetic part isn’t the key reason. So then bill told me two main reasons we should try and help developing nations even from a selfish standpoint. The first is for our own safety. If a poor country receives aid, it fosters education and economic opportunity, which makes it more stable and there’s a less of a reason for people to become desperate, which is a breeding ground for radical ideologies and terrorism. All America’s top generals agree that foreign aid creates stability, which reduces the need for military spending and makes the world a safer place. Additionally, Bill told me there’s the issue of diseases. When the next pandemic comes, there’s a good chance it will be far worse than Ebola and it will spread quickly into the rich countries. There’s a huge benefit to us in helping these developing nations get their health systems to the point where they can detect and treat bad stuff before it has the chance to go global. The second selfish reason for helping developing nations that we discuss together was for our own prosperity. After World War II, we think hey, do we care about Japan? Well, hey then Japan, you know Sony and Toyota they’re making good products. Yeah, let’s not forget Nintendo. It’s a win-win situation, you know where we want Japan to do well and make great products and you know, they’re buying Boeing Jets, Microsoft software and so having “hypothetically” hopefully The idea that other countries doing well, it’s not a zero-sum thing where okay if they do well, that means that it’s it’s bad for us. Basically, we needed to get the Japanese back to a point where their brains could benefit the world again as quickly as possible. Otherwise, it’s a waste of human capital and the world never knows Super Mario Brothers. Which raises an interesting point if you ask people who is the most intelligent person to ever live, you get various answers like these: Albert Einstein Einstein Albert Einstein Einstein Albert Einstein Mark Rober Did I tell you to say that? [Nods] What, you-! But the fact is with 100 billion people to have ever lived on planet Earth, it’s a statistical certainty that Albert Einstein wasn’t the most intelligent human. It was some random person you’ve never heard of probably born a long time ago who spent most of their daily energy just trying to survive. That’s why these packets are a huge deal when you have nearly 1 billion people spending their time just trying to find clean water every day, that’s a huge waste of untapped brainpower. Now these packets and other aid efforts like them allow parents to stay healthy and gives them time to provide for their families. Which gives their kids the opportunity to get educated which in turn creates more opportunities for the following generation and so eventually, over time, the entire world starts reaping the benefit from the contribution of this previously untapped human capital. In this way some massive breakthrough in solar technology, or maybe the cure to cancer or HIV might come from a poor country who is just a developing nation today. And I find that to be incredibly inspiring and a worthy goal. I want to thank Bill and Melinda Gates for partnering with me on this video. They just released the brand-new Gates annual letter. I will leave a link to it in the video description. It’s a great read if you want to learn how life has, and will continue to improve for the world’s poorest. Plus, you get to be inspired by people who have just made it their life’s mission to make the world a better place. You know I get to learn a lot you know, I’m gonna be working on these diseases the rest of my life. Bill Gates, living legend, eater of pizza rolls. – Yeah, not bad. – That was fantastic. Thanks so much, bro. Now we drink. [calm music]

  1. They make a lot of sense … but too bad a certain president would rather stunt the world's progress and doesn't care about what he calls "sh!thole countries".

  2. I wanted to be a nuclear physicist… But economically, that is a very unrealistic dream in my country 'coz the people here don't know anything about nukes other than exploding.

    I hope others will get a better chance as I grow old working and watching science vids in youtube in my freetime…

  3. Somehow governments or the whole world will outlaw this because it will keep the world over populated and they will lose money since it's pretty cheap.

  4. To be true saving the human race and saving the planet are two very different things saving the human race will actually damage the world I know it sounds bad but should we be trying to save everyone or is death gust a natural thing that we shouldn’t be avoiding every species has a thing that slows down its population so if we killed of Fox’s then rabbits will burst out of control they eat plants there population will grow so big they will destroy the environment so should we make humans have no killer but old age it’s that a bad thing and a good thing my opinion says that death is a evil thing that gust needs to happen

  5. What would happen if we dumped say 1 billion tons of this stuff in our oceans? OR even more how much would be Needed to clean ALL the water in the world?

  6. You may be shocked to find that reusable water filters are at your local outdoors shop. Per gallon they are far cheaper than those fancy little packets you are promoting.

  7. Correction Albert Einstein was actually the smartest of his generation Bill Gates is technically a little bit smarter than Albert Einstein but only by 10 points but still Albert Einstein never took a IQ test so therefore it would only be 10-20points difference depending on if he actually had 160 IQ while Bill Gates has 170 IQ so Einstein is technically not the smartest person in the world but you know schools teach Factory workers so now you go to school for 11 years and you become a factory worker

  8. Not very special if you come to india sometime there is a holy river (Ganga) take its water it will be dirty at the time but keep it for sometime and you will see the dirt will settle down and above there will be cleaned water

  9. Thanks for the sob story, America already provides more than most other countries, yes that’s still not not s huge percentage and we could do more but we first need to fix our own problems, then worry about other people’s

  10. I just found you and I think you are awesome. Thank you for taking the time to put these well thought out videos. You should be given Bill Nye's crown (and if he does not have one, he should be given one, and promptly handed to you). Please keep it up. I am a fan.

  11. This is beyond disgusting, no filtering or purification?? this just looks like sedimentation … fml i hope no one else does this.

  12. It truly is a bummer having so many water problems in the caribbean, but life is a little more simple having warm days and beaches make up for bummer days with water issues…Maybe. Bathing from a bucket is…

  13. Are we just going to graze past the fact that Bill Gates just said "I love Dick's."
    I know he didn't mean that but he still said it.
    Shut up it counts.

  14. Lead poisoning water also arms the more vulnerable, kids and pregnant women here in the US and we can’t solve the problem 😞 . How it’s the people of this countries can be 99.9% sure the water is safe to drink if it’s other heavy particles in the water positive charge ? Product is awesome, but please let us know, truly, does it complete the full circle?
    Thank you
    Love your channel!!
    Best
    Mag

  15. I LOVE YOU !!! Such a great platform, thank you for creating this. Thank you for making a difference. Thank you for educating all of us. Thank you for making learning fun.

  16. it's true people normally take water for granted but if 1 mistake happens you can lose all that water and this actually happened to me. so a sewer EXPLODED in my neighbourhood and the whole street didn't have water for a week
