Are Invisibility Cloaks Possible?

- This week Reactions is taking a look to see if science and chemistry could make invisibility cloaks possible. Have you ever wished you could hide under an invisibility cloak like Harry Potter or conceal your car with a Klingon cloaking device like in Star Trek? In a special bonus episode of Reactions, we celebrate the International Year of Light by exploring the science behind light, sight and invisibility. Though we can’t make ourselves invisible yet, some promising research may light the way - or rather, bend the light away.
This episode of Reactions was produced in collaboration with the journal ACS Photonics. For more information on ACS Photonics, please visit: pubs.acs.org/journal/apchd5. Additional information on the International Year of Light can be found at: www.light2015.org.

Chameleons change their colour and texture to communicate their moods or to absorb more heat from light. Not for camouflage
You beat me to it. Jajajaja
Lol, as soon as he said it, I went to the comments to see if anyone had already offered a correction.
ciucinciu Chameleons change their skin color for all three: for social purposes (mood signaling, in response to other chameleons, in response to threat), for practical purposes (in response to temperature changes) as well as for survival purposes (camouflage; look up the Smith's dwarf chameleon as an example). It should be noted that different chameleons change their colors for different reasons (some don't even change colors), and will have different ranges of colors they utilize.
Alison L I looked it up, and you're right. It was a dogmatic knee-jerk reaction. I usually associate color change for camouflage with green anoles.
Alison L Pretty and smart? I'm jealous.
Actually chameleons don't match colors around them, they change color to regulate their temperatures or to signal their intentions, so we can't talk about camouflage there
Ok lets face it, the only reason we make something invisible is to do some "research"
If you know what I mean
No
No
YeH
Yes
Why is the first thing that comes to mind pervy sage from naruto
Yes. Can’t we just analyse chameleons to find out how they can change colour to adapt to their surroundings, and then use that method to make invisibility possible
Thanks for doing this video. In my undergraduate course I did a whole paper on metamaterials and their potential for operating within the visible spectrum. Super interesting stuff and I'm glad I found a video about it
Braden Hahn Thanks! Metamaterials are very promising and a lot of chemists are getting into it.
So then why does a kimono not make u invisible if it’s made from that material
scientists: trying to figure out how to make invisibility cloaks.
john cena: laughs
Why are there no credits for the research shown at 2:27?
***** Fixed! These credits should have been included in the original video -- thanks for catching that. We've also added a note in the summary.
I have a question, if say one achieves invisibility with light bending, is someone shines some very bright external light around the area, would that disrupt the invisibility? Like create shadows of the person?
Haven't watched the video yet but correct me if I'm wrong but I think they are possible cause you could put on a suit and the suit could take a picture of what's behind you and put it on the suit and display it at the front so it's kind of an invisible cloak it will need to take pictures immensely fast especially the displaying part even faster.
Awhile ago they had cloaks that turn you invisible, the only flaw was you had to stand still.
Hyperstealth just done this
Pretty cool! :)
Is that link from good mythical morning?
A real cloaking device would be a sort of square funnel of mirrors. Or a cone with mirrors inside it.
Hmm ACS Timber Photonics. Cool dude. Wanna buy some fretwork.
Did he say BAE as in bae! lol:)
I made an ice cube transparent before its not hard to do it but i refuse to tell people how so they can't use it on the inccent.
That sad thing is, once hover cars and invisibility cloaks and all this futuristic stuff is actually built, it will NEVER be released to the public. The military or the government will be the only ones that get use them :(
Harry Potter fantasies come true please
They should have an on or off button for it too
would it be possible to create invisibility on a desired object by using frequencies to trick the human mind into believing that there is nothing where the object is Turing it invisible
Invisibility is actually a natural capability for nonhuman where they can refract light and envelope themselves in it, turning them invisible or they will look like the predators cloaking field where you can still see them if they shift their body’s
1:58 "...on the same vector that it came in," not "180 degrees from the direction it came in."
Wow. So that stuff is real. I checked out the Hyperstealth BioTechnology Corps information section and they are apparently already under security contract from the gov't. So basically this is already out there and real.
Watch out for those pesky shadows that remain during even the slightest movement. -former recondo sgt. ''rock'' 82nd abn. 32518
i remember reading up on this , so far we have like 6 or 7 cloaking methods, there was one that used magnets to make a mirage around its self, the only problem was you would not be able to see out word either
yes, it does look like a heat mirage.. like the craft appears like is in a heat mirage (black triangle) the invisible is not 100% more like 60% complete.
I wonder if you could apply this material to a jet fighter or a MBT that would be sick.
black triangle craft are being reported recently to have a visual cloak, many have witnessed
If I had access to even a prototype, I could change the world...."Lemme at em, lemme at em!"
cant u just add cameras behind the cloak and then display whats behind in front of the cloak? something like that maybe?
I am here after a company invented an invisibility glass
Some technology like this for example, should never be made..imagine the paranoia knowing people could be right in front of you and you don't even know
Sullux S it shouldn't be made public, but if so it'll probably not be free to use, many laws and company restrictions or sum
Don't worry there arw scopes that can detect heat
*By the way we have huge festival of colours every year.*
If these materials can direct light away from the object then how did scientist see it or create it or whatever?
Wait your name at youtube is the same at wengie and max
I hope invisible tanks are real it’s 6 years later
I have a full invisible Holographical Optical Element System incl, ultrasound hearing, subvocalisation silent speech, invisible luneburg superlens for Virtual Reality with over 40 tools for augmented reality.
Harry Potter here I come!
The logic is bending light around the object. It is not flawless and can be captured on an analogue camera. Anything digital, can be hacked or fried by a targeted EMP pulse. All the best!! :)
Do you know harry potter is made of vfx technique and i am reserch this cloaks technique
So chamele s dont actually do that to blend in it shows their mood
Invisible tanks. 😐 may God have mercy on our soul.
Chameleons don't camouflage themselves. Their colour reflects their mood.
1:20 Serbians rekt that airplane
Tony Stark has them beat!
maybe but if light is a wave, then just use another wave to bend it...
And answer is ???
There is one more way to be invisible
Hmm Ki-Moan , was that a joke at the time. Hmm.
Chameleons can't do that 🤥
Look up animorphs
I have seen Invisibility cloaking in use!! Govt agents!!
Hey i would like u and LifeNoggin make a video together!Like if u agree
To whoever reads this,
I hope you have a wonderful day and no matter what stay happy as that is what matters most in life,
You are truly amazing and no one can ever take that away from you,
Be happy and enjoy life,
We don't have long on earth so make the most of it,
Have a wonderful day, *Cheers, from doge in a rain coat!*
I needed that today, thank you
Shut up already you little kid and stop deleting my comments.
Jumalauta Ei Helvetti I can't delete other people's comments.
That's not within my power..
I can only flag comments but, I have not flagged your comment.
C0d0ps i wish the same for you ,may you achieve happiness and be satisfied with your life,have a great day
@@C0d0ps Thanks 😊
How do you see someone using invisibility clothing or a cloak important not kidding.thanks
"Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should."
Did you ever get an answer to you question about how do you see someone wearing one
Huh, Duke finally produced something other than racism
Lol. Funny. Not true, but funny nonetheless.
invicibility by use of bending light!
Like people disappear
People dispear or fade in front of u to scare u
People fading in front of u to scare u looking in widow
Please help
Help
Invisibility is already a thing. You just couldn’t see it
This already exists
I came here from the predator movie
One thing wrong in this video is radar dont get signals through visible light rays it uses radio waves so plezz with due respect dont say anything which is not confirmed we r watching this with some creative hopes
True, radio wave dont work the same way our eyes work thus video got 75% of the information incorrect
radar using radio frequency not a light so improve your knowledge.
LEATHER FLAMINGO radio waves are light get your facts right
Give me $1000 and see.
Light/rays cannot bend .
