How to make bamboo dragonfly by hand

The method of making bamboo dragonflies by hand is as follows:

Preparation tools:

A piece of wood, about 20 cm long, 3 cm wide and 0.5 cm thick (in fact, bamboo chips are better, but wood is easier to get. ) a small wooden stick, cylindrical, about 25 cm long and 3 mm in diameter (slowly cut from wood or bamboo, as symmetrical as possible, it is best to prepare a longer one first) and a sharp tool (please pay attention to safety). Glue (optional) fine sandpaper (necessary for those who pursue perfection).

Production method:

First make a hole in the sawdust, control the diameter, slightly smaller than the stick. The back is also treated in this way, so that the wood is cut into inclined planes. The same is true for the other end, and then fix the stick in the hole you just punched. If you feel loose, use glue

Extended data:

Bamboo dragonfly is one of the traditional folk children's toys in China, which 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 release your hands, and the bamboo dragonfly will fly to the sky, rotate for a while, and then fall.

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 helicopter propeller according to the shape and principle of "bamboo dragonfly".
