This video is a report of an experiment on mouth-to-mouth breathing. 2 naked girls and their supervisor sink to the bottom of the pool. They have one scuba tank for all of them.
Dolly is the dispatcher of the experiment. She takes a breath, then lets Aoro take a breath. Aoro passes air from mouth to mouth to Helen. Then the whole cycle repeats.
The girls are happy that the experiment is successfully completed. They are ready for new and more difficult tasks in the future.
