"I thought a spider was crawling across the floor right there, but it's just spores in my water" is surely a sentence i did not think i'll ever hear
This could be the start of a "The Action Lab, but out of context" video. You never knooow.
@@Andrew90046zero I checked out your channel but sadly no such compilation
I am quite dissapointed 😒
@@ateyaba7253 well I was hoping somone else would do that xP
It's free real estate

I'm surprised they never do this in school
Yeah
@@Flashisgreatfr hey kid, learn how to market yourself better
People just never knew. It took modern min-maxing of kits and ideas to get this far
Powerful lasers like the one used in the video are ridiculously dangerous. But if the experiment still works with a regular laser then yeah this would be great to do in school
@@StrawHatRain no I need to see styropyro make a drop of water evaporate using a laser
Hands down the coolest new home experiment I’ve seen in years. Thank you.

These type of channels should be supported and promoted instead of those useless TikTok video channels.

And make science out of School.
Fr and those stupid yt shorts reaction channels that just steal content and stare at them from a corner of the screen with no feedback
@@sawc.ma.bals. Literally tiktok trash transfers
Oh my!! I so agree!👍💕
A little something to add to this: this might work better in a vertical setup rather than the horizontal setup used here by having the drop of water on a clean glass slide or petri dish rather than having it hang off of something and having the laser shining from below or above. This will reduce some of the irregular distortion due to the shape of hanging drop. Also, magnification factor could be varied in a controlled manner by having varying degree of hydrophobicity on the surface of glass and the shape of glass.
I think the droplet has to be spherical for this experiment to work. On a slide the drop would spread out and be flat.
The light would have to go through the Petri dish. That might distort it more.
I think his laser needs a lot of space to disperse that far, hanging this vertically might require a large vertical space for this to work
@@terratec1001 yeah but if you have a coat of hydrophobic material on that glass then the droplet will be nearly spherical
What you're describing is essentially a microscope.
Just casually waiting for the video on a desktop nuclear reactor.
@redxpen thats crazy

You should tell that to diy perks
This channel is continuously impressive.

Now, it's not even for free but there's nothing i can really do here at all since i can't subscribe here from the Philippines!
It's really cool to see this, since holography is what I do professionally. We make a microscope that uses exactly this principle, just engineered to be more consistent. It turns out those bullseye patterns (called holograms) are determined by the size and composition of the particles. If you throw enough computing power at the problem, you can back out those parameters and learn a lot about what's in your sample. It's been useful for pharmaceutical formulation (where protein aggregates are a big problem), semiconductor polishing slurries (where agglomerates lead to damaged electronics), and a whole range of other industries.
I've seen this happen on droplets of sweat on my eye lashes!
Always figured it was probably a visual hallucination, or brain misinterpretation, but now given how accurate it is to this, I suspect it was the sunlight causing magnification of whatever was in the sweat.
the reason this works is because lasers are different than normal light/sunlight so i have to doubt your theory
What you're experiencing is just light refraction, the angle your eye sees sometimes happens to be the right ratio for the magnification to come out clear.
Light diffraction being the key evidence, but to you it's essentially using the droplet of sweat as a prism that happens to magnify depending on the angle you view it.
Especially being that the round profile of a droplet greatly gives to the needed ratio that is crucial for refraction to even occur, which happens with most magnifying glasses/lenses.
the more round it is, and again, depending on the angle your eye is to the droplet, will determine exactly the magnification and clarity you will see.
honestly, just shining a light through the bottom of drinking glasses you might see some "shadow puppets" on the ceiling if you can angle it correctly. I would do this all the time, never really understood it till i was much older.
yes, exactly, I did the same thing, with just my eye and a clear marble. it was definitely magnifying, because I was able to see microscopic air bubbles in the glass marble, as well as specs of dust and even small, things, I don't know what they were, but they looked like organisms of some kind.
Naked eye cannot see microorganisms at all. What you saw were probably "eye floaters" floating around and passing across your retina inside your eyeballs.
Holy shit this the same thing i did after i took a bath

If I had discovered this channel back when I was in school, I'd have been pursuing a doctorate in science by now. Sad I gave up on science midlife.
Same for most ppl. School's just there to destroy curiosity/creativity and introduce conformity.
hopefully the school system is fixed by the time I reach college
@@skyz3ra I don’t think that is true. I have never observed that. I don’t think it destroys creativity or curiosity but it sets you into realistic ways to fulfill them. But I will say this, if every student fully cooperated the system would be able to invest so much more for all of them to develop their creativities or satiate their curiosities.
@@skyz3ra I don't think it's "just there to" etc. but the effect is much the same.
You did the right thing Deepak .
Finally some experiment I have done in my childhood.
My pen laser had a detachable ring on which i could pour a drop of water and i would always check every water source with my laser 😂
my friend had a laser and he did this exact same thing but we used cheap setup lmao, and when i first got a laseri played with it but then i thought of this experiment so i trieddoing it and i put the drop on the surface of the lens and now the laser's dead, i'm so dumb 😭😓
@@maskboy2743 Even though i had a cheap chinese laser it was still water resistant 😂
@@unknownhuman9416 ;-;
its scary how water can be so dirty under an microscope. i think i quit drinking water.
Who said those bacterias are bad to you??
uh
no
Free protein
Mmmmm
Tasty
Action lab and Cody's lab on the same day. To whom do I owe thy honor. 😎
2:21 wow that second one you can clearly see rings around it, like as if it's double slit style wave effect
It just need some psychedelic music, when it’s projected on the wall.
I am so happy you put this video up I have been doing this for years with the tears in my eyes as I squint and let light through.
I love how he always comes up with great science ideas to share with all of us :D
this is just the most simple and awesome experience, and yes, teachers around the world, take notes please.
Wish you had tried a drop of swamp water. Should be some interesting activity visible.
This is the same shit that I can see when I look up at the sky. I thought I was god gifted that I could see microscopic things with my naked eye, but turns out its a fookin eye condition.
It's not an eye condition, everyone sees highly magnified particles in their maculars
Same, but then it turned out just to be eye floaties
Those particles which every one can see are wbc
@Ur Friend please go practice coitus with yourself
Hi Action Lab! I’m just fellow fan loving your videos! Your videos always supports me to keep on doing science. Thank you so much for keeping up those great videos! I’ll be here always supporting you. Thank you!
3:33 Oh no, he's going to give some spit facts too!
Your channel has been a revelation. You are doing a great job. Thank you very much for so many interesting science videos.
I just had to go give this a try and good fantastic results. You can even magnify something like a strand of hair held in front of the droplet.
I won't be surprised if he will make a video to see sub-atomic particles with naked eyes.
Its actually possible believe it or not, you can put single atoms in a high-energy state until they start giving off a lot of light

I guess this works somewhat like the first "microscope" created by Antonie van Leeuwenhoek. Where the lens he used was a tiny glass sphere. Amazing!
Is it possible to get an effect like using different light filters on a microscope by using different coloured lasers?
no
truly awesome and easy home experiment.....really amazing for a schooler...
Keep doing things like this bro... Constant support from a fan...
I was not prepared for how mind blowing this was going to be.
Wow!!! Best experiemnt I've ever see till now! Thanks!
you need to get out more.
This is cool. When I got my first laser pointer many years ago, I used it to examine the surface of countless many objects. Hours and hours of fun.
Should try this with the acoustic levitation machine that levitates small water droplets could inject different liquids.
I had Done This 2years ago in 8th grade, A very wonderful experiment!!!
Wow this is really freaking cool dude! I happen to actually be doing research with lasers this summer, so that makes it even better! Those rings of light and dark around the cells might be Airy's disks. Not sure though
You need to further develop this idea with different drop materials ! Want to see more :)
Great experiment
Thanks!
this is the the only science channel i need
I've done this experiment in my high school. And all appreciated me😀
Thank you for sharing this, I tried it out and it worked!
This is awesome! When I recognized those diffraction patterns as the same ones I've seen with interferometers... I s*** brix
I have every thing to do this experiment. Cool af man.
Not sure if anyone remembers, but an old youtuber who had a series called "Do Try This at Home" showed this experiment a long time ago. Glad to see it's being shown again!
Hey! Great experiment. Why not have a curved (concave) screen instead of a
instead of a wall, which could keep most things in perspective...
yeah cause everyone has a concave wall in their house dur
@@markylon amazing justification 👍🏽
Not only is a cheap microscope, it also comes with a badass proyector.
Man I have a scientific session with kids tomorrow about the unseeable world and you just handed me a really cool and easy demonstration ! Thanks !
I love these experiments 🤓💕👍👍
ive seen the same thing at my tears too! but instead,i shine my eye at a ceiling light and it looks a bit messed up because of my eyebrows but i can see it at the edges of the viewed light source. teachnically im using the cells inside my eye as a projection pad but it still looks as cool
that is ne of the coolest videos
so far!😋i will try it too!! i have high power 450 and 405nm lasers
Really cool video. It would be cool if you looked at other substances too and see how they compare. Like orange juice, milk, even blood might be cool to check out.
Keep up the awesome videos!
You are simply fantastic, thanks for sharing!
Oh hey I used to do this all the time as a kid, the key to better images is to use a lens that forces the light into a bright condensed circle, and that will be your viewing area. If you use cells from a cheek swap the results will be absolutely amazing! Also paramecium look cool!
Now I wanna try it! Good thing it doesn't require anything crazy
can we turn our room into club if we have that laser?
Technically yes if you make the laser point up into a ball that reflects the light from the laser in all directions
Do I really want to see what’s in my water? Nope because I drink to much of it daily 😂
too much not to much. Did all that water dilute your English?
you should try it with droplets of plant juices and test it with plants that have infections like blight.
i have had that laser for about 11 years, its no joke. your video just prompted me to rig up this fun little experiment again. i wore the eye protection and my eyes are kinda effed a little bit lol. i also went through a full set of that weird half of a 18650 battery in about 25 minutes
Great Job! Thank you!
Cool that was helpful when other people they think the water is really processed and really clean
You don’t have to go through all that trouble. Just turn the lights off in your bathroom and bounce your LASER off the toilet water and look up.
Hey!! that laser guy from the football match between england and denmark might be watching ur video for a more intense beam.
What happened at the football match?
I was wondering how many mW his blue laser was. Might be dangerous.
@@TheRainHarvester during the euro cup semi-final match between England and denmark, a laser beam was pointed out by an audience in the eyes of denmark's goalkeeper while there was a penalty kick. England team was later fined.
I haven’t even watched this vid but I can just tell it gonna be good
quality content brother... you always blow my mind lol
That’s what the floaters in my eyes look like!
Same lol
The pipette is more suspect. Very cool! Thank you.
Cool! I wonder if you could incorporate a saturated clear orbee instead of the water drop, to magnify other objects or surfaces. Thanks!
This video got recommended to me by CZcams like a million times
Absolutely incredible!!
This is one of the coolest things ive ever seen
When I was a kid in the 80’s I did this with a spoon and sun light. I would hold the round part of the spoon in the light and hold it close to my eye, it would show me all the things on my eye magnified.
If you get some incredibly thin wire in a loop you may be able to electrically modulate the drop size and if you strobe the laser you could maybe be able to make an electrically focused device.
This is a fantastic experiment that almost anyone can do. Virtually everyone has a old red laser pointer laying around. You can buy them at the dollar store. Anyone can do this.
I swear I learn more on this channel in 6 minutes than at least a week in school
also works to see darpas machine to human interface when you been marked for death and they point their gyrotron at you
Great video. I wonder if a camera obscura (pinhole camera) with bright sunlight would do the same thing at all? The rays are mostly parallel. If it could work even a little someone would have seen microbes 2000 years before the invention of the microscope!
Bacteria : Hey see pal...How handsome i am...!
This one is amazing!!
Holy .... I can actually do the same thing with my eyes, no joke. I didn't know what it was until i saw your video. I stare at a source of light(NOT a lazer, just a regular light source, small so that you dont go blind, it can be as far away as you want, even a street light, preferably at night with no other sources of light) and just unfocus my vision in such a way that i magnify the source of light. And inside the magnified light i can see dark floating spots and strings just like the ones you showed on the video. Pretty cool!!!
gonna do this with my niece for sure, great video!
Do a video explaining how light is an em wave like double slit experiment or Polarization using polaroids
If lasers weren't so power hungry, I'd combine three to get a white beam, then use this as a night light.
Bio screen saver is soothing. Maybe I'll do this on my garage door tonight.
Can this be done with blood too???
And if yes then can you please make a video
If your blood is transparent...
I sometimes used to see the tip of my eyelash in glasses reflection of light when almost closed my eyelid. It was really strange and now feeling that the phenomenon principal is same this vid.
This was awesome!
And in Australia suddenly a spore start crawl onto your hand then boom you are dead by those pesky spiders. 🤣🤣🤣
You can see this in your eyes with the right kind of light blob
I remember when this channel is on like 200k subs and holy mom, it just reached 3.21 million subs?!?!
Wow, you guys really do the neat work, congrats!
(I know, i am sorry i am late, i didn't recognize that you guys already had million subs)
Thanks to this video, I can say that I see bacteria floating with bare eyes.
Truly wonderful!
Fascinating!
If you look closely, you will notice the brightest zone of a spere shadow is in it's center. Veritasium talked about this in one video.
Science has never been fun since 1999... Thank you man
Your so cool. I like all the facts.
This is awesome 👏🏻!
It almost sounded like one of the last sentences before death: I thought spider was crawling there but was just something in the water... Interesting idea with the laser, great video!
2:50: "Look how cool that is"
Me: *trypophobia intensifies*
Sir pls make more such videos. I love these videos. 😇😇😇😊😊😊😊
