The bamboo-copter or bamboo dragonfly (Chinese zhuqingting , Japanese taketombo ) is a toy propeller that flies up when its shaft is rapidly spun. This helicopter-like top originated in Warring States Period China around 400 BCE, and was the object of early experiments by George Cayley, the inventor of modern aeronautics.
