Brief introduction of bamboo dragonfly

It is one of the traditional folk children's toys in China, and it is widely spread. Bamboo dragonfly consists of two parts. One is a bamboo handle. The second is "wings". When playing, rub your hands together, then let go, and the bamboo dragonfly will fly to the sky.

It will fall off after a while. It is a very subtle little invention in ancient China. This simple and magical toy once amazed western missionaries and called it "China spiral". In 1930s, Germans invented the propeller of helicopter according to the shape and principle of "bamboo dragonfly".

The shape of bamboo dragonfly is T-shaped, and the horizontal bar is like a propeller with a small hole on it. When a straight bamboo stick is inserted into it, the bamboo dragonfly will fly into the sky and then fall to the ground when the lift is weakened.
