Reversibility in laminar flow

Experiment no.: 3.5.7
Reversibilität durch Laminar­strömung Revised since 07/25
Vertical strips of blue and red colored glycerine, which are placed in glycerine, can be reversibly deformed by slow turning.
Figures applied to the glycerine, such as a line of colored glycerine, can also be reversibly deformed.
