| Abstract: | The volume and depth of the air pocket produced by vertical air jet from a straw were investigated theoretically and experimentally.The volume and the depth were mainly determined by the flow rate of the air jet,the inner radius of the straw,and the distance between the open tip of the straw and the water surface. |

| Keywords: | flow velocity shadow in a horizontal light surface hollow |
