I Sakshi Sangwikar along with my fellow student Gayatri Tulapulkar at CMR National PU College at ITPL, Bangalore observed salt under a foldscope on 8th June, 2018. Salt is a white transparent crystalline compound.  It is found in the rocks of mines. It is seldom used in our everyday life. Salt gives taste to our food. It…

Fibers from Nature -2 (Spider silk)

In the corner of my house, I spotted a web. Fixed it on a slide using a cellotape and viewed it through the Foldscope. I was astonished as it revealed the facts about it as a fiber material. The spotted spider web  A spiderweb commonly found in all house hold as a dreaded thing can…

Sticky pollen

I had always imagined pollen to have thick, spiny covering called exine, which had germ pores on it. I came across Morning glory plant with pink flowers. It had bell shaped flowers, with the stamens quite deep seated. I took out the anthers, which had some staminal hairs along the filaments.  I could see a…

Table sugar with polarizers

For this, I mixed regular table sugar with tap water and let it air dry.  Then observed this at the edge.

Fibers from Nature -1

I, Aman Arjel  of SD College, Chandigarh could never imagine, sample collection for foldscoping could lead me to a summer vacation project on fibers of biological origin. It all happened by chance. Thanks to my buddy Kanwar Pal Singh who noticed Calotropis fruit – a follicle (which our Botany teacher told) and chose to see…

Bubble wrap under microscope

I saw a bubble wrap under Foldscope and found this, Dont know the exact about the structure but there seem some small air sack like structure . with

Matchstick cells

The school year has begun, with new textbooks, new stuff to learn, and soon, new foldscopes for students in ten of the TSWREIS schools — thanks to DBT and Prakash Lab’s ‘India Foldscope Phase 1’. The school curriculum of Telangana State luckily prescribes quite a few microscope activities. We are trying these out, with a…

Polarized Explorations Part 3!! Copepods and Ciliates

Hello everyone! Thanks to iGEM I’ve had absolutely no time for foldscoping lately 🙁 but I’m determined to exploit this mini vacation in Ratngiri to its fullest 😀 Till now I’ve observed some pure chemicals and fruits in cross polars but this time I’ve tried doing something that I’ve been dying to try my hands…

Hyaluronic Acid dried on slide

I put a drop of a Hyaluronic acid solution on the slide.  I didn’t see anything with brightfield/polarizing microscopy.  I looked at it again 2 days after it had dried, with one polarizing filter, then both and finally with polarizing filters and a “frugal” compensator (the coverslide in our Foldscope kits).

GREAT RESOURCE! Book recommendation

Whether you are in the U.S. or not (like us) this is a wonderful resource for educators planning explorations of the microcosmos. The INTRODUCTION and background information is wonderful and the description and ID KEYS are wonderful!

Fun time with fibres and other things

From the clothes we wear to the paper on which we write, these things are made of fibres. Fibres of polysaccharides. Just how amazing these look under a foldscope…   Paper may look smooth and uniform as viewed from the naked eye, but microscopically a different story is seen.     Cotton fibres seen through…

Capillary action occuring on paper

One thing we often do while preparing any wet mount is removing excess of mounting medium; mainly by making use of blotting paper. Wondered how blotting paper takes up the excess medium so quickly? A phenomenon called capillary action comes into play. Blotting paper consists of several hydrophilic substances and water (most common mounting media)…

Fiery foldscoping!

I was curious about how chemical reactions would look like, microscopically. Particularly, combustion. However, observing one on foldscope wasn’t easy as putting the flap on would immediately extinguish any burning object. That could be solved easily by not putting the flap (it was obvious). However recording a burning object and even taking care to record…

permanent marker film

Here are some images of dried permanent marker film written on the mesh pouch provided with the foldscope. It appears that a convenient approximation of the field of view of the foldscope is one square of the mesh!

Is used makeup really that gross? – Bio60_2018

I’ve always read things online about how you’re supposed to wash your makeup brushes regularly, but like the majority of the makeup-wearing population, I do not listen to these warnings. Unlike most makeup-users, I only own one makeup brush that I use for pretty much everything, maybe twice a week. This thing has been all…

Polarized light foldscopy

I finally got myself a polarizing film. By this I can now polarize the light falling on the sample by placing the film between the light source and the sample and further by placing another film between the lens and the eye/camera I can block the same polarized light so that only light whose polarization…

A single female human hair

I had a great opportunity to meet Manu Prakash sir through DBT workshop in IIT Bombay. Simply inspired by him. I tried one of my friend human hair in foldscope.I am able to see capillary kind of structure. Experience was simply amazing     .

Our Latex experiments

We wondered what the white latex of a Ficus plant would look like under a Foldscope. Here is the experiment in 5 short videos Video 1/5: Latex in Ficus elongatus.   Video 2/5. We spread the latex onto the slide. We had two slides, one in which we really stirred the latex and the other…
