I actually just had the same realization when I sat down after work and re-watched. If I take it out, it'll look like this can't happen. So maybe adding a comment at the end will be the better solution. Thanks.
I added said comment to the video, and also created a third video to show the manipulation of physics values with a timeline.
I was going to attach the file as well, and noticed a shortcoming of Zenler: It won't let me. Hype files are not among the allowed attachment types. Second shortcoming: No quiz functionality.
