We have hair, they have things bizarre…

Animals aren’t unique when it comes to having things growing on their skin. Plants have an even bizarre set of things growing on their skin too, some of which secrete chemicals that are secondary metabolites. Foldscoping these reveal things about what ‘hair’ they have! Some of the explorations as follows : 1. Cucurbita maxima :…

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…

Compound Eyes

Unlike us gigantic creatures, arthropods do not have just two simple eyes. Everything is compound in the microscopic world. A post dedicated to some of the compound eyes I have observed as per instructions in the post  https://microcosmos.foldscope.com/?p=29111 and also by sandwiching the specimens between a coverslip and a cavity slide. 1. Housefly :    …

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…

Watching swimming bacteria in our spit

After a lovely Christmas dinner, my 6-year old nephew (H) and I settle down with a foldscope. And off course we decide to look at spit; in search of bacteria. This is video with the regular basic foldscope without light module. We use just the hanging light in the room as our light source. Enjoy!!…

Tutorial: Surface imaging using Foldscope – ice formation

I want to start the year with new year spirit. Ice crystals. It’s -26C here; yes – you read it right. Most people are enjoying the fact that it’s colder in Montreal than Antarctica. Something we should be worried about; but that’s for another day. Basic foldscope can be used for surface imaging on translucent…

Mites that spin silk; a tutorial for using micro-well slides

Here is a quick example of how to use micro-well glass slides in your kits to trap and keep alive organisms. Spider mites hiding on my #croton plant. They are really small; smaller than a dot in a sentence. Count the legs – and you know they are arachnids. But I did not know that…

New Foldscope tutorial – making wet mount slides and oblique illumination

Here is a 12min tutorial on basics of latest foldscope usage. Once you have assembled the foldscope correctly (see: https://www.foldscope.com/foldscope-instructions/), you can begin to make slides, explore and enjoy the microscopic world. Lots of latest tricks and tips hidden in this latest video: As you can see; so much can be done with the basic…

Surfing surfaces

Here is a hack with the new foldscope lens. Using a magnetic coupler and a lens, couple the two onto the phone’s camera-eye. This can be directly used to scan objects. For a reflecting light source, you can use the camera flashlight (if your app allows you to have the flashlight and the camera on…

Measuring the Foldscope Universe-1: Using the kit scale

In any scientific endeavor, measurements are a central aspect, and so I was delighted when I saw slide scales in the new foldscope kit. This meant that I could calibrate my phone camera with the slide scales. The smallest division on SLIDE A2 is 0.5 mm. Under the foldcsope at no digital zoom, that is…

Unboxing at midnight

Dark was the night and the date slipped over to the next. The wind howled as the critters froze under the million eyes of the crisp “Thanksgiving sky”.  But we were undeterred and bravely sneaked to the box, while the others slept in fear of the dark. Assembling the foldscope was a breeze, in spite…

My first mistakes… and fixes.

Hello world! I was super excited to receive my Foldscope and get started right away. I’d watched the videos a while ago and had the instructions for reference. Still I made two mistakes I’m sharing that can maybe help someone else just getting started.   The first was silly and easy to fix. I installed…

Manu Prakash demonstrating time lapse with foldscope

The video presents Manu Prakash demonstrating how to capture time-lapse using foldscope and a smartphone.  The audio is clear enough to understand the trick used.     The outcome of the activity is presented in this video posted by Manu Prakash:

“Muskaan” (smile) of incredible kids in Dharavi basti (Mumbai)

We run and document Foldscope workshops around the world. It’s our work and our passion. And in this process, we meet incredibly kids that amaze us, remind us of why we love science so much and allow us to see a reflection of our future to come. Some members of Foldscope Team (Jim Cybulski and…

How to Make an Inexpensive Microtome

Hi All, I’m making inexpensive microtomes to use with the foldscopes. Here are the items I used. You can use either an empty wooden or plastic thread spool. In order to have a surface on which to glue the nut and to have a firm cutting surface, glue a metal washer on each end of the plastic spool. The…

Foldscopes in a 6th grade class in Melrose Florida

Here’s a short slide show of our day with Laurie Alsobrook’s 6th grade class in Melrose, Florida.  Julie Johnson and I are planning to take Foldscopes to Cambodia and Laurie Alsobrook was willing and eager for us to share them with her class as part of our preparation. My write up our experience is below, but…

Folscope Presentation Wins 1st Place in the Louisiana STEM Expo!!

Our school competed at this year’s Louisiana STEM Expo.  Our presentation of foldscope and its many applications for use got loads of attention!  We were even invited to present to the Louisiana State Board of Elementary & Secondary Education (BESE) to explain how this technology can be used in public & private schools across the…

Kelilalina high school, Ranomafana National Park, Madagascar

With our partners at PIVOT, CVB and Stanford; we had an incredible opportunity to run large scale workshops in schools in Madagascar. We were fortunate that the workshop was documented by an incredible Japanese crew that documented this. I am quickly sharing this video; that allows you to see what it takes to run an…
