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 .                                                                                               …

Made a case for my Foldscope

  I bought a cheap (97 cent) plastic covered composition book at Wal-Mart and ripped all the paper out, then folded the edges of the cover to make a simple case for my Foldscope. It’s not perfect (the scope can still slide out the ends), but the plastic is stiff enough that I feel very…

Cracker Crumbs- Josh

  What do cracker crumbs look like up close? This is a cracker crumb up close.  Every crumb is unique and has a different shape. There are many different crackers that we can choose from.  This is from a Ritz Cracker.  Other crackers might be different, so try this at home.  It was very interesting.

Fractals in a tear of plastic 

“Beauty of science is everywhere around us” – I was caught saying this phrase recently; and I wanted to share more of this beauty with everyone. This time I decided to look at the curious phenomena of what happens when you cut a piece of plastic film; but with a blunt object. Say you decide…

Microbiology of Idli and Dosa

Prelude: I thought I was going to write a post on the microbiology of the Idli, but I worry this reads more like a cooking post. Apologies for the rambling, but I write for reproducibility and as a record for myself. The Idli and Dosa (also Dosai/Thosai) are popular fermented foods that originated in the…

Toothpaste – hydrated silica

This is toothpaste – (Sensodyne ProNamel) It contains water, sorbitol, hydrated silica, glycerin, PEG-8, cocamidopropyl betaine, flavor, titanium dioxide, xantham gum, sodium saccharin, sodium hydroxide, according to the package.  I’m guessing just the silica is showing here, but there might be other particles like the titanium.  Why do they put titanium in toothpaste?  That’s another…

Lichens, lichens, everywhere!

  Decided to take the foldscope on its first outing to my favorite hiking spot: Huckleberry State Preserve in Oakland, CA. Huckleberry is part of a larger network of trails that are the result of a volcano that erupted 10,000 years ago and then fell on its side. The soil is rich in minerals that…

Salt crystals growing and dissolving!

I saw Manu’s recent video showing snowflakes (ice crystals) melting to form water. I thought I’d try something similar with salt crystals, which slowly dissolve and re-form when placed in water containing a high concentration of dissolved salt: https://www.youtube.com/watch?v=-bjJVQ5kVRY&feature=youtu.be https://www.youtube.com/watch?v=wwSoW3LIg6E All videos shown at 120x actual speed. I made a super-saturated salt solution by pouring two…

Material Science of Sewing

I’ve always been fascinated by what we can learn about the macroscopic properties of materials by studying their microscopic structures. In university I’ve studied and made biomaterials that mimic the properties of arteries, and I’ve examined the structures of construction materials I’ve used in the machine shop to understand why they were acting the way…

Prints in the digital world

Printing has a long history, all the way from Gutenberg who came up with an easy way to make metal casts which could be covered with ink and then pressed onto paper to produce many copies of a book page, to 3D printing which is a cool new way to create three dimensional objects by…
