The translational and rotational motion of a camphor scraping at an air/water interface was investigated. characteristics the rotation depended on temperature, surface tension, chemical structure derivative. direction rotation, either clockwise or counterclockwise, is determined by asymmetry in shape solid scraping. essential features were reproduced computer simulation. driving force this believed to be spatial heterogeneity layer air−water interface.
