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
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.

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.
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.
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 😭😓
@@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.
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?
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.

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
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.
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 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.
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!
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!!!
Please try this Place a metal sample between two powerful magnets (both should have same power ) such that metal stays inside of magnitic field of both magnet equidistant from magnet If metal stays in middle not being attracted towards any magnet Then by doing this can you levitate metal in air
No, unfortunately this doesn't work because while it would be in force equilibrium exactly between the two magnets, this is an unstable equilibrium. Therefore it's impossible to get the metal to levitate. In fact, Earnshaw's theorem proves it to be impossible for any arrangement of magnets using ferromagnetic materials passively. However, it is possible using diamagnetic materials such as bismuth, or using a powerful enough magnetic field, even water! Here is an action lab video showing levitation using bismuth: ua-cam.com/video/E-nQPveFYYM/v-deo.html
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
Not exactly the reverse of this process (microscope), but ASML’s EUV lithography machine uses droplets to create particular wavelength light and focus it to etch silicon wafers to make chips with tiniest transistors. Bloody expensive machine, sold out for years to come and it won’t get any better with all the chip shortage around us.
Your eye is somewhat a microscope. If you look at the sky you will observe dots. These are WBCs and you can see without microscope! This is blue field entopic vision.
You know the light is dispursed over a much larger area after travelling through the water drop. He 100% said the water drop is being used like a lens. Its why you get such a larger viewing area on the wall and not just a tiny dot. :) Now, dont look at the laser before it hits the water tho!
What about using a microscope slide and cover plate. Significantly less magnification but maybe some from the phase change or maybe use a curved cover plate?

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
