Therefore, a microgravity experiment in a parabolic flight, in order to develop technology for measuring the surface tension (as an important physical property value in connection with the Marangoni convection) in the microgravity environment was conducted.

In the experiment, It was unable to measure a highly reliable proper frequency or to confirm the effectiveness of this measuring technology.
