1: What: A thin (1mm) slice of the superficial peel of a València Orange When: This afternoon, 27 April 2022 Where: My kitchen in AZ, Orange acquired from Sprouts Market How: Consuming the orange and carefully slicing off a section of the remnant peel with a sharp kitchen knife to place on the slide
Conclusion: Oranges indeed have the promised hue microscopically, although I was disappointed to not be able to resolve some of the finer textures of the peel 2: What: Paper towel fibers Where: My kitchen in Northern Scottsdale, AZ When: This afternoon, 27 April 2022 How: Carefully dissecting a small, somewhat transparent layer of paper towel from a larger combined sheet
Conclusion: I wasn’t able to see any texture, though the white color suggests light did pass through the sample. Was my sample too big and insufficiently transparent? 3: What: Tap water Where: My kitchen, with tap water provided by the City of Scottsdale When: This afternoon, 27 April 2022 How: Moistening one of the slides and carefully applying the slide cover, being careful not to get the foldscope wet
Conclusion: In the US, our tap water is generally exceptionally safe, but you never know…. 4: What: Dirt from my backyard (which should be high in organic matter) moistened with a bit of water When: This afternoon, 27 April 2022 Where: Scottsdale, AZ How: Collecting a small sample with my hands and sprinkling it on a pre-moistened slide.
Conclusion: This is texture! There’s a lot going on here, as we can clearly see something grainy (dirt? sand? flesh-eating bacteria?) through the fold scope
