    What a fantastic post. Absolutely beautiful.

    Would love to know more – how did you get access to an octopus. Could you share the macroscopic view as well.

    Keep exploring. Fantastic image!

    Hi Priti,
    This is really a very good picture and it shows Octopus teeth in great detail. I ‘m facing difficulties in making test slides. Which all samples can one see under foldscope? I have so far been unsuccessful in that regard. Please help.

      Thank you so much! I am currently using the lens with magnification of 140x, you can easily observe all the sample which are observed under 10x objective of compound microscope under Foldscope.

    Dear @aneesh,

    You might want to watch a few tutorials on how to make slides at http://www.foldscope.com/tutorials – videos – specially for wet mounts. Important to remember, when you make a slide; your sample should be facing the lens. So if you are using a cover slip – the cover slip side should be down towards the lens. That is the most common mistake in mounting new samples.

    Here is another detailed tutorial on how to make wet mount – see video here: https://microcosmos.foldscope.com/?p=29464
