3 DIY Microscopes with a Laser Pen | Shed Science

[@CyPhi68]

I do Upward Bound here in the US for 5 weeks every summer for high school ages about 14 - 18. I do the science portion. Each science "course" is 3 to 6 days in 1 1/2 hr blocks. We've worked with laser pens in the past to show refraction, reflection, (including Snell's Law and total internal reflection) and filtering (for example shining a green laser through a red filter). But using laser pens for a microscope looks like great fun. I want to include more life sciences since that is my background but some of those experiments take many days or even weeks. This idea is one class period. Thanks for the idea. On another note about refraction: Get several, 6 to 8, straight sided glass jars and arrange them in a semicircle. Beakers work also. Fill each containter with water and add 1 to 2 drops of milk. Then shine a laser into the side of one jar at the end and, if you do this just right, the beam will curve 180 degrees and come out going the other way. And the cloudy water lets students see the beam. Then I tell them that this is similar to how fiber optic cable works.

I'm impressed by the last one cuz I've always wondered what that was "floating"

[@Seamemaria]

uau! I´m so happy to have found this video and your channel. Very inspirational. I am doing my PhD in marine microbiology and I must admit I have never thought about creating my own microscope with household materials. I have to try Microscope 1 immediately to show people at home who have no clue of what I´m talking about when I say microorganisms. Love it!

[@pattrriot]

thanks for the video with the laser, I have never tried it and I will definitely try it, do you think the laser harms the microorganisms in any way?

[@amazingbollweevil]

Good lord! You must have the most beautifully equipped shed in all the United Kingdom! Furthermore, that water-drop laser? Whoa! That was awesome.

[@SallyLePage]

+amazingbollweevil Isn't it cool! Took me AGES to line up though - thought I was doing it wrong for a while. And yes, my Oxford shed is pretty neat ;)

[@bigfunsoftware368]

The laser without the lens can also be used to amplify images, place a water sample on the shiny side of a blank cd and bounce the laser off the cd onto a wall... the lines on the cd act as a lens... it works with a mirror and regular laser too but requires more distance

[@donyaingrida]

This video was included in our online module 💜 May I ask how did you calculate the magnification of the smartphone microscope? (I want to know the model of the phone and the focal length of the laser lens if it's okay)

[@Youcanscienceit]

I love the DIY science, and nice to see a Shed Science video again (not that I mind your adventure videos).

[@SallyLePage]

+YouCanScienceIt Thanks! I'm planning a lot more science videos now my AA vlogs are almost over.

[@wattersmd]

Fantastic video Sally!

[@SallyLePage]

+Mark Watters Thanks Mark :)

[@SudhaSharma-wn4li]

+Sally Le Page this is the best experiment that i have ever seen but i need the explanation behind the first technique as i have to perform or a school tomorrow so pleaseeeee give it to me as fast as possible

[@petaca39]

Hello, good video regarding the experience with the laser, what do you think about this, that device would not be properly a microscope? I think that maybe it will be more like an optical microscopy device and with respect to that, you tried with other laser colors to see if any color It is better than another for projection images and the latter could be improved in some way that device

[@zulukilocharlie]

my qualitative study continues - still yielding positive results! you're awesome Sally!!!

[@artstechnology7809]

Very intelligence projects. Bravo 👍👍👍👍👍

[@davidvc4560]

These ideas are pretty awesome :) Thanks for sharing.

[@brad.bryant]

HEYYY awesome video but I have a question.. does it matter how powerful the laser pointer is?? can one be too powerful or is there a sweet spot? I have a pretty high-powered one but I am kind of afraid to try it

[@SimonClark]

What!? A science video? On Sally's channel?? I never thought I'd see the day... This was really good though. Showoff :p

[@SallyLePage]

+SimonOxfPhys I know, right? It's like I'm branching into new territory! Who do I think I am, a scientist or something?!

[@SudhaSharma-wn4li]

+Sally Le Page this is the best experiment that i have ever but i need the explanation behind the first technique as i have to perform it at school tomorrow..... So pleaseeeeeee give me the explanation behind it!!!!! And try to do it a bit fast

[@eldattackkrossa9886]

@@SudhaSharma-wn4li how did it go

[@hairyoldhippy]

Slightly more engaging than my school physics teachers. A good education is essential for opening up a whole new world of disappointment.

[@myloflex]

Love it...another quality science video!

[@SallyLePage]

+myloflex Thanks :)

[@dragoknight9]

Wow.. thanks for confirming what I always thought.. the microscopic things I see in my eye.. when I look at the sky.

[@lemonman5114]

she’s constantly smiling, why can’t i be that happy

[@carlosorff]

Great video, I just found it amusing, that while using the laser there was no warning, but turning on the headlight - "Don't stare at the light for too long"

[@fdnychaser469]

With the laser len can you use more than just water

[@BensLab]

Great video! I made one with the lens...it works fantastic!

[@SallyLePage]

Fab! Glad it worked for you :)

[@ARVash]

I've got those same tweezers, THEY ROCK.

[@mateuszcielas3362]

so, on first one, can u magnify it even more, btw how small objects u can see? and how to change the resolution?

[@bassemb]

This is amazing! Especially the laser one!

[@vomaudaykumar9406]

hai you done well, i always thinks one , that is we use a magnifying lens for to see small objectives like micron size particles in visible light, but when we can see nano particles with simple equipment like magnifying lens.

[@richardlucero9265]

SALLY, You're so adorable!, love the hair!

[@charlidog2]

Loved it. Science for the win.

[@SallyLePage]

+charlidog2 Yey

[@meme115]

I did that when i was kid it maybe 10 years ago...Now in 2020 I really missed those of my Experiments... that's why I am searching it manually to restore some data on mind from my childhood life... I am the one who actually watch a Tiny animal which are living in a Moss just using a $0.30 cents Laser Lens... And also I watch the Far distance object just using my Dad convax spectacle and using a little Concave lens which can actually find on any spherical glass bottle... This video is so mean for me that actually remind me my whole childhood...

[@hasanthalansakara9801]

Very nice explaining. Good luck.......

[@anisleebibart6485]

I love listening to you teach

[@edgeeffect]

For number 2, you can also get a lens out of a DVD/CD drive if you've got some old computer junk laying around and you don't want to destroy your laser pointer like in this video from "randomtronic": kzbin.info/www/bejne/l6a0qIKqp7qBa6M

[@Tritium8]

i looved the DIY stuff. great video

[@SallyLePage]

+Tritium8 Thank you! It was fun to do - maybe I'll try more :)

[@ZeroMass]

You're not seeing anything smaller than dust sized particles with the laser.

[@تثقيفتقني]

i have made the laser microscope and its works so good thanks for the good information (:

[@kabirkashyap9128]

Wonderful

[@moustaalhatt7414]

Great and simple ideas

[@TheCritic108]

So nice of you

[@berlinbooth902]

how are you attaching the lens to the cellphone

[@jayesh6233]

Thank you so much

[@laijhenpepito2855]

what kind of water did you use for the first one?

[@dexterdev]

she said "filthy pond water"

[@fernardoweng]

How much is the laser pointer power? 5mW or more?

[@ykeen]

Can we use Red Laser pen for this experiment?

[@theredstonebuilder1120]

I know this is really late (and you’ve probably already got the answer) but a red one works fine, I used red and it’s beautiful

[@nx7640]

Thank you Sally

[@ibewatchinu]

I love the laser microscope, definitely gonna do that for the kids (with safety glasses).

[@ryenn7982]

THAT WAS WONDERFUL!

[@robertom7326]

What kind of laser are you ussing? excellent video btw!

[@redchris05]

Wait, what? A Shed Science video - albeit minus the shed? I remember these...

[@SallyLePage]

+Christ J I think you might be one of very few who still remember...!

[@shailendrasingh6936]

Thanks maam it helped me very much

[@owl6218]

you don't need a syinge for the drop. I puched a neat hole (3 to 4 mm in diameter) in a sheet of water and dripped some water on the hole. a spherical drop forms in the hole and stays put. I positioned the sheet of plastic at the edge of a table, with the water drop on the overhanging part, and shot downwards with the laser through the drop, placed a sheet of paper below for the screen. unfortuantely, the red laser pointer i used does not produce any such effect, it just produced a field of scintillating light point against a uniform background. but it is daytime...am going to repeat at night in a darker room, and hope to catch this sight.....

[@monabey5254]

hi can i use transparent glue to stick the lens

[@Eniramos619]

I remember doing these experiments in school!

[@jahidhasanemon1521]

I tried it but not working. Should the lens be bigger than camera? My lens is not covering the whole camera.

[@maxpein9866]

So what are those little pulsating orbs? there almost in every picture someone mades with a laserpointer when they use water , ive even seen them in sterile saltwater--- can anyone explain?

[@EnglishLaw]

Single cell organisms. Your water possibly hadn't been sterilised as much a you thought or had quickly started forming life again.

[@BEERMAN684]

floaters !!! who knew ! Always wondered what they were

[@willemvandebeek]

Yay, shed science is back! :)

[@SallyLePage]

+Willem van de Beek Yeah, in the back-but-don't-expect-another-one-for-a-while-because-they-take-ages-but-I-am-planning-a-load sense ;)

[@willemvandebeek]

Quality over quantity is better anyways, no worries. ;)

[@KhaschuluuMunkhbayar]

Awesome :D Last one is very priceless :D

[@soonersciencenerd383]

goto a thrift shop, and look for old digital cameras, hard drives, take it apart, and remove the lenses. put the lense in a holder, and try that for a microscope! i made 2, and they work well, not 1000X.... very nice video!

[@phpdepot]

lenses from hard drives? what are the hard drives for?

[@soonersciencenerd383]

defconcepts I meant CD drives. the lenses that I found can be used for microscopes. I tried it, and it works! not a lot of magnification but it's something to work on. other topic, any computer drive, will have gold inside! check it out!

[@maheshdatar5313]

very nice and useful

[@rajeshkoppa2367]

Impressive

[@Salival46.2]

I discovered you through the Rooster Teeth Podcast, but I subscribed because of your wonderful accent. Keep making great videos.

[@omsingharjit]

Is it possible to see virus using it , they are too small 100 nm 🤔

[@mohamedraaifrushdhy6693]

What is the magnification??

[@wishfulbuddy]

amazing last one

[@PhrontDoor]

It looks like a Leica M60.. how much are those?

[@madhushreedatar5197]

nice video. Good project for students

[@aswingsharif6729]

Fabulous. Is it.....100x magnification?

[@eunicemanguiat870]

Your lens with phone can you do two or more lens if is so magnify i tried but i see the bactria not of my specimen inthe lens when im stick 4 or 3 lens in my phobe and the light i see the super tiny of bactria i dont know hats that ang my sample not magnify

Thanks you😊

[@gaurikagupta251]

can u give an explanation for the 1st one

[@Hydra11-11]

Bro it's 2019. Nov 13 now. Would I still be able to get that hover board

[@beautifullmegan]

xd its 2020 right now and i was thinking the same thing

[@foerdie]

The last one is my fav i wanted to know what are those things flying now i know

[@renanfaria4811]

wonderful video

[@XIGuyIX]

Ever read any papers of Michael J Nelson's? He did a lot of papers on dung flies. Not the best flies to study however.

[@SallyLePage]

+XIGuyIX I don't think I have. Dung flies I imagine aren't quite as pleasant as fruit flies!

[@AG-yj1jv]

So...what if we create a light ring using fibre optic strands from holiday light up decor and the flash from one of the old smarphones (if this is possible) and then stack TWO cell phone cameras...? Could we go smaller? How low could we go? I want to study the surface of tiny minerals and the stuff on their surfaces. (About 1/4 the • you see here---> ¡). And is the contest on for 2021? Can non-scientist big kids over age 50 participate?

[@BeingDengineer]

beautiful ideas...so that you.

[@MrCuriousScienceANDfun]

Beautiful!

[@FedorKai]

If you were in my school, I would never skip class.

[@fgm1197]

cool. wait, im gonna try this right away

[@johnyes95]

Heard you talk about snapchat in this video and I'm just curious, do you have a public snapchat? Would love to follow along in your studies at school and as you make these videos. I just started to watch them after watching the new Rooster Teeth video and as a chemical engineer, I'm finding all of these videos to be amazing!

Sally you are so incredibly cute! And then you have a British accent too? And you are geeky smart as well? My head just exploded! Loved the video by the way. I REALLY want a laser pointer now! ;)

[@jafinch78]

Might be a little over your head (as is mine for now)... though was recently reading about and found this video regarding a DIY AFM from an old Cd/DVD/Blu-Ray RW: kzbin.info/www/bejne/a5PUpp2XocmUebM Was wondering about the beam splitter cubes in the range of RW devices for use in an interferometer to make a wide band spectrometer. Figure can be an upgrade, goal DIY cost effective, to the more common webcam spectrometer.

[@909sickle]

Same :) She is quite adorable and super enthusiastic about science too!

[@eirhoncalica472]

in the first experiment i see little organisms to with my eyes.when my eyelashes are wet and if i close my eyes a little bit and focus on my wet eyelashes i see the little organism.

[@waleedahmed4591]

same but those are not microorganisms

[@theUglyManowar]

yes they are... The same thing is happening if I am not mistaken? Eyes are closed a bit, just the right time of day ( angle of sunlight ) laying by a window. light streams through eyelids creating a stencil sharp enough to refract light that is reflected at just the right angle and ICKY icky POO! There are self motorized organisms swimming with obvious purpose ( non random ), If those amoebic like transparent jellies I catch in those reflections swimming in my eye orb are not micro organisms... Than what kinda organisms are they?
