This article deals with the motion of gas bubbles induced by Marangoni convection. The bubbles are suspended in a liquid medium. The linear motion thus induced implies a variety of interesting technical applications. The experiment described in this article demonstrates that “bubble motion induced by Marangoni convection” can be used to balance buoyancy and to delay gravity‐induced segregation. This allows finely dispersed suspensions to be maintained for some time.
