(1) First, prepare the original Lego and rubber band, a flat beam with 15 hole, a big curved beam and four black nails. Add a 24-speed gear to the four black pins to fix them. In addition, two flat beams with 13 holes are fixed with long pins before the finished beam. Fix a long pin, a big pin and a 3-hole flat beam on the third hole of the flat beam, fix the long pin and big pin on the fifth hole on the other side, and put big pins on both sides of the flat beam with 15 hole.
(2) Take a 9-hole flat beam, with the hole facing upwards, put it into the groove, and put a big pin on the last hole. Cover the rubber band, put the rubber band on the big pins on both sides, and then put the rubber band on the big pin of the 9-hole flat beam, and the small pistol will be ready. Pull the pin, you can shoot, and the bullet can be made of paper balls.
Lego bricks are children's favorite toys. One end of this plastic building block has a protrusion, and the other end has a hole into which the protrusion can be embedded. There are more than 1300 shapes, and each shape has 12 different colors, mainly red, yellow, blue, white and green. It relies on children's own hands and brains, and can spell out endless shapes, which makes people fondle it. It is called "magic plastic building block". The hometown of Lego bricks is in Billon, Denmark.
The inventor of Lego bricks is Ole Kirk Christiansen, who was born in Filzgov village near Billon in 189 1. He has superb carpentry skills. When he was young, he was keen on making all kinds of small toys. Small planes, cars and small animals from his hands are all lifelike.
Although he doesn't know how to do business and his toys are often unsalable, it doesn't make him give up his hobby. Later, his spelling toy "Yoyo" finally became all the rage. 1934, he designed the "Lego" trademark for his building block toys.
