Kites are the most popular toy in the world. In Japan people enjoy carps swimming in the fragrant May wind. They belong to the same family from the fluid dynamical viewpoint. We have made wind-tunnel experiments on the performance of carp model. As a simplified model we chose straight round hollow cylinder of various size and weight. If a model is light enough, it floats in the flow by a single support thread attached to the mouth. Obviously, the lift force acting on the cylinder supports the model. If a model us heavy, it start violent oscillations. The reason for the oscillation seems to be due to the stall of cylinder wing. Models of carps suspended in the wind tunnel show similar performance. The best way in realizing a stable swimming is the choice of connecting corps to a rod.
