First, take out a rectangular colored paper, fold the colored paper in half twice along two central axes, the two ends of the rectangle are folded into triangles, and then folded into two opposite triangles along the middle. Then fold the same origami, fold the two corners of the new origami inward, and then plug the corners of the two origami together to make a simple dart.

For children, origami can exercise finger flexibility and develop hands-on ability and innovation ability. It must be done step by step. In this process, children can also develop the good habit of doing things step by step, and also cultivate their own observation and attention.

Origami effect

The "origami mathematics" derived from the art of origami proves by equations that any geometric form can be simulated by origami in theory. With the help of computer software aided design, origami researchers can fold more complicated graphics than before. In Kamiya Satoshi, people folded a dragon with scales and claws from a square piece of paper 2 meters by 2 meters. It is said that there will probably be no more than 20 people folded out all over the world.

On the other hand, modern origami is not only an art, but also a new science, namely origami mathematics. It has been applied to the storage of parachutes, satellite solar panels, car airbags, and even the structural design of Hubble Space Telescope has benefited from origami mathematics.
