The summary is:
The video is about how to scientifically watch a solar eclipse and what phenomena to look out for. The narrator interviews Dr. Gordon Tulipan, a plastic surgeon and an eclipse fanatic, who has created an app that tells the exact contact times of the eclipse based on the location. They test the app in Tennessee and explain the difference between anular and total eclipses, and the events such as shadow bands, diamond ring, and Bailey's beads that occur before and after totality. The narrator also promotes 23andMe, a genotyping service, as the sponsor of the video. He encourages the viewers to get proper glasses for viewing the eclipse and to send him videos of shadow bands. He also directs them to his other channel for more information on how to use a camera to capture the eclipse.
