The Bamboo-copter, also known as the Chinese top, is an ancient mechanical toy that dates back to ancient China. It is considered one of the earliest known flying devices in human history. The Bamboo-copter consists of two or more rotor blades attached to a central bamboo shaft or axle.

To make it fly, one holds the Bamboo-copter by the central shaft and spins it rapidly between their hands. As the rotor blades rotate, they create lift, similar to how helicopter blades work. The upward force generated by the rotating blades allows the Bamboo-copter to hover briefly in the air before descending.

The Bamboo-copter is a simple yet ingenious toy that demonstrates the principles of rotary-wing flight. While it does not have sustained flight capabilities like modern helicopters, it serves as an early precursor to the development of rotorcraft and contributes to the understanding of flight mechanics.

The Bamboo-copter holds historical and cultural significance, highlighting the creativity and inventiveness of ancient Chinese civilization. It showcases the early exploration and experimentation with flight, setting the foundation for future advancements in aviation technology.
