Introducing Other Teachers to Foldscopes!
video using foldscope, observing local pond water After bringing the foldscopes to the teacher training class the professor wanted to keep my foldscope – Umm, NO! Everyone quickly agreed how useful the foldscopes would be when taking students out into the field for observations.
Great starter slide
Feathers through the foldscope. I found that the feathers are easiest for new users to focus on.
About the time I used Foldscope for the first time
So I attended the first workshop Dr. Manu did in collaboration with the Gov of India. Honestly, It was a day of mixed feelings. I am a biology major, and I have used a microscope so many times; I lost count. Although I had heard of the foldscope earlier, I thought that it might not…
The stratum corneum
I have been wanting to do this experiment ever since I saw Manu’s post on volcanoes on his skin and the tatoo post. I essentially wanted to stain my skin and foldscope it. I had a somewhat erroneous idea that I might see some nucleated cells. I just had to do the experiment to see what…
Food for a nation – what’s in my “Atta”
I have lots of memories of taking wheat grains to the “atta mill” – called Chakka. It used to be a tough job – I was small (only 10 maybe) and me and my brother would manage a bag of grains on a pedal bike and take it to the mill. We would wait for…
Silver Crystals Using Tollens’ Test Reagents
Have you ever seen the Silver Mirror trick at a chemistry show? That’s when silver is precipitated out of solution onto a glass surface. The demo consists of a series of clear solutions being combined in a glass flask. As the presenter swirls the flask, a shiny mirror forms on the inner surface of the…
Pretty Powder- Emily
This is a face powder. I simply used a brush to apply the translucent powder to the cellophane tape, then put the slides under the Foldscope. One can see the slight shimmer affect it gives off, and though it looks incredibly fine, when one looks at it under the Foldscope it is, in fact, grainy…
The Structure of a Bee Wing and How It Affects Flight (BioE Spr2015)
How can bees fly? One of my favorite quips is that scientists long ago succeeded in determining that bees cannot fly. Indeed, I always loved the way bees fly, like they are dangling a great mass beneath frantically flapping wings. We set out to explore the question: how does the structure of a bee’s wing…
Throwie LED as Foldscope light source
when we shipped the first batch of Foldscope; we made the decision of including only a limited number of light modules. The rational was to encourage users to do day-light outdoors microscopy. Since most of these packages were going to far away places; we were worried about if the battery might get screened. Here I…

Effect of Electrolysis on Rust
Students in the CTE Autobody Careers performed electrolytic rust removal on old parts. These are images of the rust and residue collected before and after the treatment.
Micro Fiber cloth -Daniel
Today I was wondering what to put under my Foldscope. I decided to take a small strand off of one of my mom’s micro-fiber cleaning cloths. Once I put it in my Foldscope, I was amazed to find out that these fibers were much finer than hair. This really shows how well they can pick…
Secondary presentations
Greetings again Foldscope community. About a month ago I posted about presenting the Foldscope to the Science faculty at my high school (I’m a teacher, not a student). It went great!! my colleagues are super excited and I’m presenting the foldscopes to 3 classes (AP/IB) later this week. I also have done some more work…
Shapes of Nature
Reticulite is like glass in rock form… A frothy volcanic rock that forms during vigorous fire-fountaining of lava. It is so full of bubbles that it floats on water. It is like very fine pumice made of glass, and has the lowest density of any rock, with a porosity of up to 98 percent. The...
Joel-Piece of paper
Have you ever wondered why paper is so thin and easy to break? There is a legitimate reason for this little problem that I found after using my foldscope. As seen in the picture above, paper is not just a solid piece of some fibers that are all fused together into one piece, but quite…
chamomile flower
This is the bud of a chamomile flower. The way I got this pictures was, I took the flower bud and pinched off the yellow center and placed it on the slide I then put a flash light up to back and took a picture. As you can see the little spec looks so…
Crystals that looks like city maps – Frozen project
Here is another entry inspired by the “Frozen Project” started by a fantastic pair of Foldscope contributors. Thank you for initiating such a fascinating series. Search “frozen” project on the website to get links for all the original posts (now a series of 6 posts). This time, I accidentally made my own little crystals. I…
Glimmer and Glam -Emily
Sephora’s Mini Glitter Liner Set has an assortment of color ranging from “Evening Blue” to “Sweetheart Pink.” The goopy, pond water looking substance I tested on my Foldscope was a glitter liner in the shade “Mystic Teal.” Some of the ingredients are glycerin, calcium aluminum borosilicate, and triethanolamine.
e.l.f. -Emily
Why not check out stuff you put on your face? e.l.f. cosmetic line’s stick concealer in the shade “Ivory” has a pasty texture and is used to cover up blemishes or redness on the face (for you boys who didn’t know.) It’s $3 at Target. I twisted the concealer up and put a swipe on…
Foldscope Plan
The Foldscopes arrived a month ago and I shared them with a few fellow medical laboratory scientist. The plan was to see if we could put it together. It took about a half hour to assemble. We were happy to get in on this project and eager to get started. We were able to use…
Senior Show – Progress! Drawings
Hello there, Foldscope community! I have returned to post in-progress images of my drawings for my senior show. I am also going to attach my blog post to this post because many of you have been wondering about my rationale for choosing such a “random” and “photographic” subject to draw. http://rocklandantiglitter.blogspot.com/2015/03/foldscopes-and-403-round-1-of-images.html?spref=fb I welcome any feedback…
Cola!
In this photo cola looks like the moon! 🙂 ∗♥
Oil :)
I mix oil water. So I saw the state of oil rose to the surface.
Red Lacquer!
I think it looks like supernova . …
