 In my biology class I had the opportunity to swab and plate samples from my hands and feet, in order to explore the skin microbiome. I was interested in comparing colonies with my foldscope, as comparing colony morphology with the naked eye can be difficult.   Bellow I compare two colonies that were similar in shape and size, but slightly different in color.

 I photographed the dark yellow colony both immediately after creating the slide and about 5 hours later when the sample had dried onto the slide more.

<h5>
 I photographed the pale yellow colony about 5 hours after making the slide. The pale yellow colony seems less dense.  The pale yellow colony also has a less distinct color even under the foldscope.

<h5>
 On Tuesday during my dance class, a callus fell off of the bottom of my right big toe. Of course my immediate reaction was that this is a perfect specimen to examine under my foldscope. You can see the dirt remaining in the skin from having bare feet on the floor.
 <br/>
 <br/>
 The lines in the images, created by the pattern of the toeprint, are very interesting. In the foldcope images the lines appear almost parallel.
