Today in our ecology class lab at Princeton we used Foldscopes to investigate the world around us. I stuck the slide sticker to my skin in order to collect material from my skin. It was initially challenging to find an image, but with some patience and tinkering I was able to get a great picture of cells and a hair. This is a great tool to inspire curiosity in the world around you! It is amazing how folded paper and some small metal pieces can produce such an image.
