"Trapping a particle with a lazer"
That's the type of thing you hear in scifi movies when they don't know how to explain something and they just make words up. But it's real.
Is your cat vaping? Nice
@@digi3218 the cat in the box? Maybe it's vaping , maybe it's not...
@@830jps ok Schrodinger
For real. Just like the insanely fast movie hacking. click click click ×100... I'm in.
All Sci-Fi is just science you haven't made yet.
People specifically scientist need to start thinking more outside the box. This civilization would have teleportation by now if you all did.
This guy explains stuff that I never heard in my life
@hey bro bot bot
Agreed
@Muhaiminul Hasan It's not Action Lab Guy?
Go to school
I thought your name is 17 mins ago
This guy is one of the few action- science channels that ACTUALLY brings out mind blowing content
Edit: Thank you guys so much for 1.5k likes! I've never crossed 100 before!
What a feeling!
bruhhh report da thingy above
Yep
really
So true
bruhhh report da thingy 5 comments above me
The parabolic reflector setup actually does allow you to walk around it and see the frog from half of all sides (that are visible through the hole) as long as you keep your view within the hemisphere above the hole on top of the reflector setup.
yes you are right but the point he wanted to make is that it is an illusion and not real holograph
Yes. It’s a “real image”. The light rays converge. I was teaching a unit on this.
Yeah I was going to say this as well. I recall this from a place in Vancouver, BC called "Science World". It's a projection from all directions.
I interpreted him to mean you can't turn the frog over and look underneath it.

Yugioh developers: write that down, write that down!
Is that a Charles the French reference?
Preach!!!
EXODIA OBLITERATE!
oh shit we're coming back from the grave
Its was made 5 or more years ago
It's amazing to see how much inspiration science fiction movies can give for people to actually create those things, makes you wonder about what amazing inventions we haven't even thought about yet.
science fiction is destined to become science fact! :D
FTL will change human civilization
If you can imagine it, It can be made.
Yep. Also an influence to the magic community!
Most science fiction is based on theoretically accurate models in order to honour science.
2:45 absolutely have no idea 😵
i think he is saying that the laser can control the particles and move them around. and also maje the particle just float.
I never thought I'd see something like this, but humanity continues to amaze.
Yah, and here I just can't understand how is it possible to trap a light particle mid air using a laser
I did try this 5 years ago
I'd hoped to see it in my lifetime.
I guess you are VERY easily amazed. This is bullshit! Holograms look NOTHING like Pepper's ghost and they are already ACTUAL 3D images!
BET ITS A START OF A NEW ERA.......probably in like 50 years it will be main stream
May be even early
Bruh no joke I made this thing in 2014 I was 10 years old at that time so it's old
@@xlantboi first how old are you second how did you get that much lasers like it is not that easy for one guy to do
@@sohamwaghmare2801 no i did not made that laser thing I made that 3d hologram with plastic
@@sohamwaghmare2801 it’s pretty easy to make, actually
Just WOW. 3D images you can physicly interact with! That means a Holodeck is possible during my lifetime!
This is a great first step towards that, we have the light part, but we don't yet have 'force fields' to actually make the projections material. The Holodeck in Star Trek produced projections that could physically hurt you. Water that you could swim in. Apples that you felt when they fell on your head. Explosions that could throw you to the ground.
This tech is nowhere near that. It is just the image, the physical part is missing. But it might be possible, we just haven't yet found a way to do it.
I always wish I’d have been born like 1,000 years later because I’m going to miss out on some amazing things. But then I think about it and we may be the last generation that gets to enjoy things like nature and wild animals if things keep going the way they are. So maybe we are currently living in the best of times.
@@mmaaddict78 I mean, we are probably the generation that sees Humanity become multi-planetary. That is big.
At the same time, we might also be the generation that sees World War III.
I'd temper that expectation a bit. Effectively we just invented powered flight and your looking forward to the space shuttle. That still means it could possibly happen in your life time, yes, but will it be publicly available in that time? Probably not. My bet is that it will be publicly available at desktop scales in our life time, but a hole room sounds pricey, expensive, and keeping people from being blinded by lasers when they are free to walk around inside the projection will be very challenging indeed
Bruh imagine the epic yu gi oh duel with this technology
This is cool but the underlying system is the real spectacle. I've always imagined lazer on lazer 3d imaging, this is great.
@@HelloKittyFanMan. Scotty noooo
Isn't it spelt laser?
@@polydullmemes3497 so, as long as it attaches to their heads, you can name it as you will.
@@TrentTationnaiseXization That isn't right though, that's like saying if I wanted to I could say "Meatstickything" instead of hotdog
@@HelloKittyFanMan.
Why say it doesn’t exist rather than say it’s misspelled? It sounds like you’re saying lasers don’t exist since we clearly know what they’re talking about.
I half expected you to end with “checkmate globetards!”
This is the second most promising research related to light that I have seen. The first still belongs to the camera taking shot of moving light beam!
Which is not a single shot but bunch of them put together so that we can have "a shot" of a beam of light, just because you know light it's freaking fast... Though a very impressive research, I like it better this one
@@arturosoto7312 Agreed. This is the future right here in it's infancy.
This is a great achievement. As a 3D being, we have innate understanding and essentially absolute power over 2D stuff. 3D stuff is harder for the uninitiated to wrap their head around.
Now waiting the shapeshifting 4D stuff...
This comment is so underrated
I feel the same way! Mind blown with 3d projections!
this is the birth of real-life sci-fi!
yaas
I’m so glad they did the USS Enterprise and Princess Leia.
Ah yes, non-fiction science-fiction
@@kykoa exactly my thoughts lol
Dr. Smalley would've made a very promising andrologist
sorry whats a andrologist 😅
@@SnickersEatsCookies andrology is the branch of psychology and medicine which deals with diseases and conditions specific to men
@@diegoaguilar1954 I think it's "physiology" and not "psychology"
@@diegoaguilar1954 ohhh
Iron Man's holographic projection is finally becoming a reality !!
That’s actually so cool!
Mr. Carfenharghen was 5 mineral late
Amazing such a small particle can be moved so fast through air using only light.
Yeah, I missed the whole part about it moving. Pretty sure he said "holds it in place", which was misleading. Maybe I missed something but I had to find an article to figure out that IR lasers push and pull a cellulose particle around at speed while it's being synchronously lit with R/G/B lasers. Refinement could get rid of the light bleedout with autofocus sync and a nice sharp point and large enough particle. 2 or more apertures some distance and degree apart, 90* is best, to keep the image from scrambling when touched. Would love to see someone DIY this. so cool as it is rn.
I learn more from this Channel than I did in years of School
Man I have to admit you always have pretty interesting ideas and that's why I love your videos.
This is so beautiful, I almost cried
This is cool.
Now imagine this on a larger scale coupled with 3D scanning and lidar.
Great job! Can't wait to see further development!
The simple images they made are already beautiful, imagine how good these images are going to get in the future!
now I can have catgirl holograms
Yes

I was hoping you'd show a way to create one at home 😂
Make a cut off pyramid out of some acrylic sheet and place it on top of your phone/tablet. There are many videos to display like that and they have all 4 sides view as well (so if you look from behind you see the back of that thing instead of all front images from every direction as in this video).
here's a video ruclips.net/video/7YWTtCsvgvg/видео.html
@@nofserc5219 thank you for not Rick rolling me
And here's how you can do it at home! All you need is a roll of toilet paper, some duct tape, and 100 microwave ovens...
Thanks action lab. I heard about these 3D holograms long ago that are touchable but totally forgot about how it works. Now I got it again with the particle thanks to you. Great video, as usual!
Man please make a longer video on this topic it is fascinating and I didn't really understood how these things works!
*Starts describing the images at **2:30*
Me: "Yes, I absolutely understood everything you just said...."
I’ve watch so much action lab that I get half of what he says
34t
So proud of your ignorance
Bcz of him actually I'm loving Physics 😁
So happy I found this channel! Brilliant content!
Your 3D guy look like he's about to make a home run ......
in a police chase
Finally. I've been waiting my whole life for some evidence of progress in real 3d hologram technology.
Same here. I thought a lot about how it could be done, in my highschool years, and came up with a similar solution. It is nice to see that it is actually possible.
imagine if you could get many many different infrared lasers with many particles and create a large display.
I can already see it happening.
That Dr is good enough, smart enough, and doggone it, people like him.
I recall seeing something about this 3 years ago or so. Seems to be improving pretty quickly.
There’s a watch in call of duty that has a bunch of holes that vibrate the air around it and it shoots a laser that has the time out at it
Amazing! If this is developed further, we could create a Star Trek Holodeck! :)
We just need the 'force field' part that let people interact with the projections physically. For example, if an apple, projected with this tech, falls on your head, you don't feel it. But in the Holodeck, you would feel it.
I just saw their video few months ago, it was recommended in my feed!, glad you made a video on it
I have been waiting for some awesome technology like this to implement in live theatre!!! :O thanks for sharing this with us! :)
That's EXTREMELY cool!
The force is strong with this one :)
Pow!!! I am completely blowing away!!!! Your best video till now!!
Incredible work, look forward to you following any advances in this field please!
There was an arcade game with real live actors and a cowboy theme around in the 80s that used parabolic mirrors so that the characters in the game seemed to be tiny people waking around on the table. *EDIT* Time Traveller, it used laser discs, I thought they were really cool but to play it cost £2 in the 80s so I never did.
I remember that game. It was expensive in the US also. Played it like 1 time because what kid has that many quarters? But the time I did play it, it was mostly acted out scenes with not much user interaction
@@TheUltimateWord Yeah I’ve heard I didn’t miss much as far as interactive game play was concerned, and btw I just looked it up and according to wiki it was released in the early 90s, could’ve sworn it was earlier but memory is fickle.
Imagine watching a real 3d horror movie
You and your content is appreciated by millions
Incredible...what we've all been waiting for...I can't wait!
Love it, cant wait till we all have these at home in like 2030 or something
Seems a bit early, it is only 9 years! This is currently research. For it to become commercial, and then mainstream, it would probably need more, like 20 or 30 years
Other than that, I totally agree
-What -*-kind-*- of particle though?-
I looked it up, they use airborne cellulose particles.
They want to use a plane of said particles in the future, instead of a single one.
That way they'll be able to produce bigger & more complex images, than the simple 3cm-wide ones they can do now.
The fact that it scans the image in makes this so much cooler to me. Like the first tvs (and I guess modern ones too, it's just more noticeable on old CRTs)
HOLY CRAP THE NOSTALGIA!!! I USED TO DO THESE BACK IN 2016! these were really fun to make back then
I saw this some years ago I’m surprised people haven’t seen this
Yep and in 2014 I made this thing by myself I was 10 years old at that time
same.. i remember seing this few years ago too.. even had some diy video on how to replicate the glass using plastic too.. works just the same..
This guy is amazing... I want him as my teacher
This is so awesome!
Thanks for the video, keep doing good content :)
I am so glad I found this channel!
Wondering if the same synthesis of focusing on a "particle" works in a vacuum, as well as in free air, or for that matter, would it possibly be diffused by different gases like neon or argon etc, or combination of such? Good stuff to ponder...thanx Action Lab!
p.s. or even liquids like water?
p.p.s. or solids like crystals?
Yes optical trapping does work in a vacuum. I imagine that you can move the particle faster in there too!

OK DUDE
R/cursed comments
Cringey but effective
Wonderful!
Keep enlightening us with more such innovative stuff! 👍
Love ur videos man 🔥🔥❤️
Cool, I thought this was going to be about the ultrasound volumetric displays, not lasers.
0:49 Well, you actually can see what's behind if you have a better video on the phone that shows the object from different angles.
Anyways, really interesting video! 😀
I used to play with the first one quite a lot. Thanks for reminding me of this.
Amazing. I’d love to see this work in real world applications soon!
Amazing!!
I had a question, does refraction occurs due to the compression of light due to greater density when coming from rarer to denser medium so it moves towards the normal?
Refraction is basic bending of light due to change in optical density of medium. When you say compression of light,i assume you mean wavelength. However a transparent medium shouldnt do that ideally. The bending occurs due to change in light velocity.

Man gonna do it to light
Wow BYU is doing great work with this
I remember reading about this technique as a kid. They theorised that it may be possible to create structured images instead of random noise. And here we are. The madlads did it.
Ok , so when are the guys at crypton future media gonna start projecting real 3d hatsune miku ?
That just made me to say "Holy Cow"
Holograms you can touch?
Hatsune Miku, here I come
Another interesting 3D display was posted on Hackaday recently called VVD (the creator's username is Madaeon), which works a bit like 3D printing. The model is sliced into layers, which are successively projected onto a screen as it's whipped up and down quickly by a pair of stepper motors.
Plz make videos with the aspect ratio 20:9
Why?
It’s better
“Real 3D projections you can touch”
Don’t give people ideas…
@SpaceMan626 😳
by commenting this you just gave me that idea
@SpaceMan626 it's actually "nudge"
I love every bit of your videos ❤️
That is amazing. Thank you for bringing this discovery to my attention. =) So cool.
so cool it’s like an analog version of this new 3d technology. interested to see how this improves over time
That's amazing. Thanks for your videos
Loved these
Laser optical tweezers are so much interesting but I never thought that they could be used like this :O
Right? That's an application I didn't see coming!
This is so mindblowingly cool!
This is just awesome!
Beautiful!
Oh my god that would be the coolest gadget feature ever!!!
This is the coolest thing I've seen in a while
This means if a large holographic dinosaur made with this technology runs through me or tries to bite me, I'll actually feel the impact of it on my whole body and face.
Honestly this dude seems like the nicest guy in the world. Like if his videos weren’t absolutely awesome as they are, I’d still subscribe 😂
This is one of the coolest new technical discoveries I've heard about in a long time. I suspect it will result in some really fascinating applications as it develops.
This is even better than 3D imagery. You can interact with it.
Your "Today im gonna..." get's me everytime.
That is really awesome!
Just love your content... 🔥
Looks so cooool! 😲
Now this is some next gen stuff
You are doing great work ❤️❤️
Bruh , how you not a scientist and receive some prize this channel is so good
