Abstract
The fruits of many plant are carried and flowers are also swayed by the wind. If the flow of air around plants can be visualized, the science behind it will be interestingly illustrated. In this study, the gas flow around cherry blossom fruits, clover flowers, maple seed propellers, and dandelion pappi as spherical and propeller-shaped samples is demonstrated using a Schlieren optical system and a high-refractive-index gas. The observed gas flow corresponding to the sample shape was well characterized by fluid dynamics features such as the Coandă effect. The results of experiments in which the flow of gas around plants is visualized are useful as a scientific education material for fluidics and optics.

Physics Education seeks to serve the physics teaching community and we welcome contributions from teachers. We seek to support the teaching of physics to students aged 11 up to introductory undergraduate level. We aim to provide professional development and support for teachers of physics around the world by providing: a forum for practising teachers to make an active contribution to the physics teaching community; knowledge updates in physics, educational research and relevant wider curriculum developments; and strategies for teaching and classroom management that will engage and motivate students.
