Make a paper Leeuwenhoek microscope - complete instructions

Antonie van Leeuwenhoek first discovered microbial life in the 1600s using a simple, single lens microscope that he made himself. This video gives instructions to build your own working Leeuwenhoek microscope, including the actual lens itself, using simple materials you likely have around the house. This exercise is great for teaching and teachers.
Additional instructions and downstream activities are available on the Keeling Lab web page: www3.botany.ubc.ca/keeling/mic...

[@Kim-tr5op]

[@alifr4088]

[@Kim-tr5op]

@@alifr4088 i think so. just found out its getting a series this summer

I tried this and it works !

[@lakshmanbheemagani5782]

very simple and easy than foldoscope.it is the worlds simpliest microscope.and its focusing mechanism is also very simple and workable

Thank´s for you video is very interesting.

[@brodieharley7040]

@Boden Thatcher Thanks so much for your reply. I got to the site thru google and I'm in the hacking process atm. Looks like it's gonna take quite some time so I will get back to you later with my results.

[@brodieharley7040]

@Boden Thatcher It did the trick and I now got access to my account again. I am so happy:D Thank you so much, you saved my ass !

what is that glass like in the sticky tack?

Excelente

I feel like the phrase "O Ye of Little Faith!" fits me here, I like how this is simple and still used, but I admit that I'm having a hard time believing that it would actually allow you to see bacteria. I mean, I'm sure that you can't see all types of microorganisms, but I'm curious. I'll have to try this out and I do believe you! Its just personal curiosity, but for example would you be able to examine a sample of blood with it? And what about using a glass stir rod instead? The end result might be a bit bigger, but I'd imagine it would still work right? Thank you for posting and making this video!

[@animehair05silently88]

if i remember correctly from high school, the reason a van leuuwenhoek microscope has such high magnification is because the curve of the lens is so sharp from how small a sphere it is, and the process shown here would make a *very* small sphere i think (except compared to things on the scale of what you look at with it)

[@DeBiologieLeraar]

nice, i am going to make this into a school project

[@nelsonwang9706]

me too hahaha

[@griffin5226]

What changes when the glass bead is made bigger or smaller?

[@honza_568]

the smaller the bead the higher the magnification

[@Sahil-dz5ur]

What's its magnification power?

[@user-ue7uf3ww1k]

Can I see the link

Where do you purchase the brass replica?

[@lakshmanbheemagani5782]

why do u need brass one when it is easy and cheap

My dear subscribers and scientists I am Vignesh I want to make a microscope so I am begging at your feet can u tell me what is the glass tube used by this bro can u also tell me where can I get these tubes cheap under 500 rupees or any medical s or pharmacy

[@hili467]

For people that don’t have access to glass tubing and a blowtorch, could they use fishing line and a lighter to make the sphere?
