Centripetal swing tray video bloopers

While making a video on the classic centripetal swinging tray demonstration, some of the variations shown were being tested for the first time as I was making the video. The result being that not everything went as smoothly as possible. However, overall I was impressed with the changes and look forward to taking them a step further in the future.
