    Agree with jbourne8 and BennyTheBeaver. I want to time tag the video, and make a time plot of (1) the angle that the popcorn falls showing the right end of the room dropping, and (2) and popcorn angle at the left and right of the image (how trapezoidal - as the room tilts back and camera points...
