Welcome to Foldscope

I recently had the wonderful pleasure to visit Manu at his lab in Stanford.

Here I am at home, assembling my first Foldscope.  What fun!

First time with the foldscope

After playing around a bit, we took a little pond water from outside to take a look. Here’s my first Foldscope image (many more to come!).  This is just great!

 

Small ciliate organism from the backyard.  I believe that this is probably a protozoan of some type, maybe a Stylonychia?

This one has a long stalk that attached to the sticky-tape. I made a video where you can see it moving to eat the littler organisms swimming by. I believe this might be a type of vorticella.

    Glad to know you have the microscope immediately up and running..

    That is a strange stalk!! I realized if you are using pond water, a simple trick with a glass slide and cover slip with double sided tape might form a nice chamber that allows things to swim as well. This way you will see them behave – it’s remarkable to me how fast ciliates make decisions!!

    Play with different type of slide preparation – if you have access to glass slides, it will really give you a clean field of view. The tape slides are really valuable for dry samples. It’s also nice if you are also working with younger kids – where tape slides don’t break..

    It was so great to see you guys..

    cheers

    I made a few little videos of this.. they indeed swim around very fast. I might add them to this post once I trim them to be smaller.

    For this set of images I used a single paper slide with tape on the bottom, a drop of pond water placed in the center, and then a second piece of clear tape on top. I was quite surprised with the nice images. I plan to repeat this experiment with glass slides and post some nicer videos, so I will try out your suggestion.
