Self-propelled toy boat

This movie is another demonstration of the Marangoni effect. Here, a toy boat is placed on the water and a drop of dishwashing soap is added on one end of the boat. This causes the boat to move in the opposite direction. The motion of the boat is propelled by surface tension forces caused by the lowering of surface tension at the point where the soap is added.
