Tuesday

I started the day off with class. Roger Easton taught us. Turns out that they used his designs in the movie National Security 2. I've seen the first one but not the second. I think I want to see it now that I know who designed the documents that was used in the movie. Also, his dad is behind the whole GPS system. I thought that was pretty cool. I think he was very intelligent and you can tell he knew a lot about geometric optics and wanted to teach us all of it.

I spent second half of my day dying the PVAs. First, we stretched them. Then, we put them in potassium iodide, iodine, and water bath. This time, we only dipped the PVA instead of putting the whole thing in. Also, we made another path with just potassium iodide and water. When we dipped the PVA, there was no color change. Turns out potassium iodide only works with iodine mixed together.
