Resonant Frequency: Bottle Experiment (0:51)

*****
This is a video without any spoken words. Therefore the English subtitle track - http://www.amara.org/en/videos/iHrFhKPhv3Ow/en/830322/ - describes the sounds that are heard in it.

The Metadata: Audio Description "subtitle" track - http://www.amara.org/en/videos/iHrFhKPhv3Ow/meta-audio/830423/ - transcribes the texts and describes the actions appearing in the video, so as to create a time-coded script for a possible real audio description file for people who can't see them.

The Metadata Geo subtitle track - http://www.amara.org/en/videos/iHrFhKPhv3Ow/meta-geo/830450/ - integrates the contents of both the English subtitle track and of the Metadata Audio subtitles track, so as to produce a downloadable text transcript that can be used by people who cannot play the video.
