# Flipped vs. Not Flipped It turns out that leaving the bioplastic in its original form after casting makes it clearer. This means not flipping over or removing the bioplastic from its original casting position. Note: this only really applies to film bioplastic. This experiment was quite simple. First, I cast a sheet of Ag11. After letting it sit for ten minutes, I cut it in half. I took one half and flipped it over, and left the other half untouched. Twice a day, I flipped over the originally flipped sheet, making sure that it didn't create too much contact with the glass, so it was slightly elevated and air could get under it. A better way to do this would have been to hang this on a clothesline of some sort. \ --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://nicholsonlabs.gitbook.io/labs/bioplastic/experiments-with-bioplastic/flipped-vs.-not-flipped.md?ask= ``` The question should be specific, self-contained, and written in natural language.
