    Ah thin film interference. One of my favorite things. I've actually plotted out the colors you should get in Kaleidagraph, based on the wave theory. For normal triphosphor fluorescent light, you get a very distinctive color pattern that can be seen at 3:53. This order of colors is specific to the light source and would look different if you used an LED light or an incandescent light instead. The first few colors tend to stay the same though, as long as it's normal white light.

    I really do love titanium and how "unique" it is (from the process used to make it, how "strong" it is, how it's more complex to form, how heat resistant it is etc.). To me it's the most fascinating thing in metallurgy when you first discover it. Also Action Lab, I know that we all have a right to make money off our services and I understand that ad revenue is a good source of it, so I just wanted to say that I'm glad you openly disclosed your sponsor at the end of the video.

    When you look at metal shavings from a CNC mill, you can see that it takes on a very strong pinkish/purple color due to the strong heat generated when shaving the pieces off.
