What's the difference between Lego toys and other toys?

Interest cultivation, production technology and educational significance are three different.

1. From the perspective of interest cultivation, "learning while learning" is the highlight of Lego toys.

2. From the production process, compared with other toys, its biggest advantage is food safety, which is refined from top petroleum and can be used.

From the educational point of view, tall building blocks are educational toys, which not only make children have fun, but also hope to develop their intelligence. Through building blocks, it takes a long time to cultivate children's practical ability and test their patience when building, especially when playing with small particles of building blocks.

Extended data:

Lego building block is a kind of plastic building block invented by OleKirkChristiansen in Denmark. One side is convex, and the other side is 1300. Each shape has 12 different colors, mainly red, yellow, blue, white and black. ?

It relies on children's brains and hands-on, and can spell out endless shapes, which makes people fondle. It is called "magic plastic building block".

Most Lego bricks have two basic components-the upper protrusions and the inner holes. The bump of the building block is slightly larger than the distance between the hole and the side wall. When you squeeze the building blocks together, the protrusions will push the side walls outward and push the holes inward. This material is elastic and can keep its original shape, so the side walls and holes will squeeze the protrusions. Friction also plays a role, which prevents two building blocks from sliding apart.

The projection hole joint system uses the principle of interference fit-the tight connection between two parts based on friction without other fasteners. You can use three 2x2 boards to make a 2x2 brick, or use three 2x4 boards to make a 2x4 brick. Alternatively, 2×4 bricks can be made of 2×2 bricks and boards at the same time. The colors of raw materials used in basic Lego components are blue, black, dark gray, green, light gray, red, yellow and white.
