One of the first things I attempted to view was a piece of onion skin.


 <img alt="onion skin -best light_sq" class="alignnone size-medium wp-image-28687 gcloudimg" data-attachment-id="28687" data-comments-opened="1" data-image-meta='{"aperture":"1.7","credit":"","camera":"SM-G930W8","caption":"","created_timestamp":"1511102387","copyright":"","focal_length":"4.2","iso":"200","shutter_speed":"0.071428571428571","title":"","orientation":"1"}' data-image-title="onion skin -best light_sq" data-recalc-dims="1" height="300" src="https://storage.googleapis.com/microcosmosdelta.appspot.com/images/transfer_28686/onion-skin-best-light_sq.jpg" width="300"/>


 The fold in the skin here actually gives some depth to the image. Natural light through a window seemed to work best as well, especially if not directly facing the window.

 I will have to try cheek cells next. Will be a good opportunity for my science students to compare animal and plant cells.
