I LOVE the concept of “frugal science”, what a truly wonderful thing.
"By boxing in ourselves we can think outside the box" -Stanford Researcher
his mind is in the clouds
im waitig for the dislikes n that pun
This kind of thinking is what we should reach for. Talk about conserving resources.
I remember when I visited Pakistan my cousins used to use this with flattened bottlecaps to cut through objects, the speeds were insane.
I used to make these when I was a kid. Didn't think about the potential medical usefulness then for some reason.
Too bad, you could be a millionaire
Crowbartender IKR they sold them right beside ma kindergardten back then... i used to buy them for RP 3000

that paper spinning thing, was invented in the Dominican Republic in 1965, and its called FuFu because of the sound its make when it spins, it was also a toy, and people instead of using paper they flattened soda caps with a hammer to make it, the intention of the game was to cut the other players rope.
It was invented long before that. Where I live in South Africa it is called a Woer-Woer (pronounced voor-voor)
Not sure about the paper version specifically, but there are records of similar toys having been made out of different materials in the early 1800s. And according to the Wikipedia page, native American cultures and China had something similar as far back as 400-500 B.C (I didn't fact-check the sources, though).
Great work Dr. Prakash. Together with Foldscope, these will make a real difference.
can you please do a video showing step by step how to build one. one the could spin up to a 5 ml vial. this is amazing, thank you
This is remarkable. So simple yet effective, cheap, easy to use, genius..
I made these as a kid before they used it as a blood centerfuge
@@lonelyblackhole727 That's cool. But being able to take one step further to connect the dots, realizing that you can use this as an economical, lightweight, portable centrifuge... that's genius. That's something you can only really do by actively brainstorming for new ideas and solutions.
THIS is the tech development we need! not “more advanced and complex” but more simple and accessible
Do you have to decant the stuff out of the capillary after its spun? Or do you just analyze it through the capillary. I just wonder this because I feel like the tube is so skinny the stuff would be harder to remove than a traditional tube
Bruh my dad used to make these in his rancho in Mexico when he was young for entertainment
here in philippines too.. using a bottle cap...😂😊
@@sekheisiamapalad4395 yes we used to cut paper, leaves and small sticks with flat bottlecaps
Here in India Too
Where do you buy them ??
Used to make these to play with as a kid and battle as to who can cut the opponent's sting first
Good Job!!
oooh the foldscope guy❤️❤️
damn, used to make these as a kid...
With a solar panel and lithium cells you can have low demand electricity anywhere.
Also there is an aspect of efficacy to the expensive equipment, you can load 20 samples and go accomplish stuff, and the samples can be larger and better precessed for less uncertainty in the results, the types of tubes used have other testing advantages as well and the machines last for decades of near continuous use(like 10 million samples);
The paper spinner does one or two tiny samples and requires somebody to spin it for 10 minutes, at a cost of $30 an hour that's about $3-6 per sample; not including the amortized machine cost, this would be 30-60 million dollars for the same number of samples that the big machine processed for only a few thousand dollars including cost of electricity. Please know that cost for an employee is not the employee's pay, usually the cost is near double the pay rate.
Wow, I used to play this when I was a child, with flattened bottle caps. Pretty sharp actually.
this is really an amazing invention!!!
I remember making these as a child. My parents made sure I used cardboard but eventually used the lids of soup cans. Lots of fun
Want is used to collect the sample at 0:31?
That's amazing! Awesome!
Beyond genius, this is applied genius to the most exquisite exactitude
amazing! true ingenuity
This deserves so many more views and likes.
Hello sir which type of instrument use for making of paperfuge
chetan rathod String, two paper discs, some containers and two plastic cubes
Mind-blowing!
I used to play with a toy like that years ago
How do you make those
Llego el momento en que el diseñador de la maquina original finalmente sabia que llegaría...
My friends used to make this and fight with others with it.
Inspirational.
It's difficult hear the voice over the music. I would be nice to hear this without any music at all.
Another fascinating video... I just came up here becoz our centrifuge stopped operating becoz of brown out. And there is no generators to supply electricity . Too bad, i need to go back to the town just to centrifugate blood samples..Our blood donors just horribly wait too long... If i had that tool it can be a back up in case it might happened again...
How do you use a paperfuge tho? Where is the blood inserted and how does it stay in the paperfuge?
Watch the video :/
Can the disign be applied to fit a larger sample i wonder.
Why would you need a larger sample?
@@Danielpall3 To get more sample. The more sample you have, the more you can use it for different types of tests and experiments.
I think the bottleneck will be the force required to pull the strings, and the durability of the device. If it's made with paper + fabric thread, I'm not confident it would withstand hundreds of cycles of pulling and spinning with heavy samples. So you'd probably need something more durable and somewhat more heavy and expensive. I imagine it would still remain far more economical than a conventional centrifuge, though.
I watched this without sound and I'm extremely confused.
what is the material of the string
A normal string
On phillipines i bought that thingy toy i and my classmates play that always it was satisfying never thought it was very helpful 😮😀
I remember making that out of Coca-Cola bottle cups and mat strings.
Can u tell me how to make it
Imagine that touches to your hand while sppining.
It's just paper. It will not hurt you
_Hashir _ papercuts are no joke. Have you seen those videos where a saw made of paper cuts through PVC piping and can dent metal?
Good job
This is the shit I've subscribed for!
I used to have one of these as a kid. It was made out of wood!
Love it..❤️
Now I just need one that can handle a liter.
Two questions :
1) how can you make this keep continuously rotating only in one direction, and you can keep adding energy to it ? (like spinning mops, or vintage old spinning top )
2) how can we incorporate it in a bicycle?
3) how about a skateboard working with this principle, where you just pull a string?
I love the genius of this man's idea. I wish more people think like this. Limit yourself to a box so you can think outside
Isn't it for school project also
this is so cool! hellz yes!
The best toytool you can have
I swear people sell that things in my village as a TOY
Why not the cheaper hand operated ones? Theyre just around $50 new. The problem I see with this one is it has to stop for just a bit when its switching the rotation direction. Not sure how import that is, though. Also, if something breaks, the operator is going to get a face full of glass and blood >_
genius
i wish there was a way to diagnose covid that easily
It's that who made a foldscope
eth namala pandathae soda muudina kondu akunathallae
this has already been done before
Anyone ever used this for something else? Maybe making a butter? 😂🤣
But srsly, this hand centrifuge is very useful in a lot of applications that involves separating materials by centrifugal force.
Wont the sample fling into your face at one point or another? That could be bad
I was wondering about that, too. I must be missing something.
Zac Lee it's in a little holder so it won't go flying out.
Americans, in the middle of entertainment (Hollywood) Indians, in the middle of Science. Super proud :)
Karthik Acharya ... what?
Stanford is an American university. America is a country of immigrants. I'm american and I come from Norway, he's not Indian, he's a member of the American melting pot.
Mya Elbows He is Indian born...and has done his graduation from India
Siddharth Singh, you might do well as to stop focusing on attributes that people cannot control
Zac Lee He has done his graduation from India..if he wanted he could move out... He is not an American citizen..he is currently an Indian studying in America
There's a really fun game you can do with this.
Get the metal cap off a bottle.
Flatten it and make 2 holes.
Get 2 strings(those that stretched are even better) and put 1 string through each hole. Then now you can spin it and play that game.
Well good job. You just created a portable chainsaw
is he Terence McKenna?
Manu Prakash.
too easy ,, I will use it
it's sad how little views this has
this is what happens when all the dentists can agree on one brand of toothpaste
How complex human mind is!!!🤯
We Indian kids have played with this as toy since antiquity
They could make such equipment much cheaper if they wanted to in the market. But obviously the medical industry is a bloated greedy corporate scheme nowadays, at least here in the US.
Its less about greed and more about poor management and bureaucratic incompetence.
Also there is an aspect of efficacy to the expensive equipment, you can load 20 samples and go do other stuff and the samples can be larger and better precessed for less uncertainty in the results, the types of tubes used have other testing advantages as well and the machines last for decades of near continuous use(like 10 million samples); the paper spinner does one or two tiny samples and requires somebody to spin it for 10 minutes (at a cost of $30 an hour that's about $6 per sample; not including the amortized machine cost, this would be 60 million dollars for the same number of samples processed by the big machine for a few thousand dollars)
Why only 100k views?
Mark Rober's video got millions of view.
Ko forget it.
I make it everyday by bottlecaps
I flatten the cap and poking a hole at the right part
OK, it’s been ore than 3 years. Any signs of the revolution yet?
JackFate76 yes
Fadli -Kun I see.
@@JackFate76 it's mostly used in poor areas in africa
Shouldn't this be available on Amazon
No, it's made particularly for the underprivileged, that can't afford legitimate centrifuges. I'm sure you can find one somewhere though.
rave orbital
Someone already has a really cheap centrifuge on the market. They designed it after a salad spinner!
is it less then a dollar?
but the rpm isn't fast enough
Rick W www.popsci.com/this-super-cheap-paper-centrifuge-can-spin-at-125000-revolutions-per-minute
It says salad spinners or egg beaters reach 1,200 rpm.
Rip when it breaks and shit goes everywhere.
Extra Mental oh no where ever will I find a piece of paper and a string...
Savage, my comment wasnt about the device itself breaking and not being able to replace it...
Extra Mental yeah, I realized when ***** commented.
It's actually a indian toy
Could? It already has.
Uhh
crazy how little views this video has when compared to something so possibly helpful
Thats our toys we used during childhood 👍 why using paper make yourself using plastic
cost to make $0.02. What it will sell for in US healthcare system: $600. Now if you actually think of it that's how most your medications are. If you want cheap healthcare just get out of the states
Whirligig?
Centripetal force, not Centrifugal force!
Ken M, is that you? It's Centrifugal
to clarify, it's the centrifugal force that separates the components in the liquid.
tipomartins you trolling right? centrifugal force doesn't exist. it isn't a thing.
as an actual force, no it doesn't. It's a perceived force.
Get Off My Lawn, You Dang Kids!! get your old ass in the house.
6th nice vid
Mere friend ki tabyat kharab hai uske liye pray kro
Filipinos makes them, but for entertaining, using bottle caps
another Indian jugaad
This is a simple toy. I have the exact same one but with a wooden thing in the middle. How is this an "invention"?
Poop do you think you could find something like this in nature or do you think someone had to invent it?
Taylor H This person is presenting this as something new. It isn't. That's all I'm saying
Yeah I had the same reaction too, as I used to make these with my cousins when we were kids, but with this version you can load in blood samples to test them. An important difference I think.
Also the thing he did with the coil of coils which supercharges it, making the "paperfuge" work, pretty awesome stuff.
jakeekaj9000 He didn't "do it". My toy can do that too. He didn't make it so his thing can do it. It's native to all strings
this proves Indians are far more intelligent than others
Have you seen India?
