**Let us start from the Yangshao Culture in 5000 BC, and explore the origin of the "lock"; then challenge the Luban lock, which is said to have been issued by Luban in the Spring and Autumn Period, to understand the ingenious and meticulous mortise and tenon structure in ancient architectural construction; From the perspective of Matthew, I can see that the mechanical clock he brought in from the Western world caused a dazzling wind in the Ming Dynasty and entered people's lives.** ★Professor Huang Qinfei of Normal University, Brain-STEAM brain wave research guidance and research and development ★Jointly recommended by more than 100 primary and secondary school teachers ★American STEM.org certification **【Magic old house money box】** https://live.staticflickr.com/65535/51552873223_6155f56910_h.jpg Take you across the gap of time and explore the ancient lock world of Yangshao culture. At the same time, it is not only a wooden lock, but also adds the function of a classified money box, so that after unlocking the door, children can observe the coins that are put in through the inclined planes of different angles. How many degrees and accelerations fit the size of the opening to fall into the correct position. With the addition of the color painting group, children can also create the most dreamy color of the money box in their hearts! ｜Little knowledge of Yangshao culture｜ Wooden locks are the earliest locks in ancient China. Most of the locks used in modern times are the gradual evolution of ancient wooden locks. The basic structure is simple. The holes on the door allow tools such as bamboo poles or wood to enter from the outside, so that the door can be activated. The wooden bolt opens and closes the door. It is said that in the Yangshao Culture from 5000 BC to 3000 BC, people at that time used wood to make ancient locks, but there is no authentic product left. ➤ Product Details Difficulty level: ★★☆ (the highest five-star) Assembly time: about 1.5~2 hours Recommended age: 6 years and older Included in the package: graphic assembly instructions, painting pigments + watercolor pens Product size: 17cm*11cm*24cm Packing size: 30cm*23cm*3.5cm Material: non-toxic wood Origin: Taiwan **【Luban lock】** https://live.staticflickr.com/65535/51553555095_f833c71203_k.jpg Deconstructing the ancient ingenuity and launching the world's only complete set of 21 aromatic components with multi-national patents, more than 50 combinations of "six sub-lianfang" can be freely changed and reorganized. Combinations are divided into three levels: entry, advanced and ghosts. You can also use your creativity to create more combinations, train spatial logic and brainstorm at any time, and develop infinite creative space for you. ｜Little knowledge of Luban lock｜ In ancient architectural construction, the tenon-and-mortise structure was used. This structure is widely used in wooden furniture and buildings. It can make the building structure stable and withstand the force without nails. This ingenuity is designed to be playable. In the Luban lock in hand. It is said that it was designed by the legendary woodworking figure Lu Ban, and it is also said that Kong Ming invented it according to the Eight Diagrams metaphysics, so the Luban lock is also known as the Kongming lock. There are many forms of Luban locks. Among them, the most classic "Six Son Lian Fang" is a group of six strips, and the concave and convex on the strip are used to mesh with each other to form a three-dimensional cross. ➤ Product Details Difficulty level: ★★★★★ (the highest five-star) Recommended age: no limit Included in the package: more than 50 solution instructions, you will not get tired of playing all day Product size: 7cm*8cm*8cm Package size: 30.5cm*13.5cm*2cm Material: safe plastic Origin: Taiwan **【Swing mechanical clock】** https://live.staticflickr.com/65535/51552639826_e38e96758a_h.jpg The Italian missionary Matteo Ricci paid tribute to the pendulum mechanical clock and presented this Western imported product together with the scientific research results. We simplify the principle of the ancient pendulum rod, insist on not using electricity, and use the combination of pendulum length, gears and weights. Children can try different combinations of the three during the assembly process to easily understand the mechanism principle of the mechanical clock, the principle of the pendulum rod, and the gears. , Escapement system design, can even admire the greatness of the ancients' invention of timing tools, stimulate scientific sensitivity and interest, and is an excellent opportunity to practice and learn! ｜Little knowledge of escapement system｜ In the world of watches and clocks, it is often mentioned what is the "escapement"? The escapement was first invented by Philo of Byzantium, Greece, but the escapement used in the clock mechanism was developed by Thich Nhat Hanh, a monk in the Tang Dynasty and a court astronomer, mathematician, and engineer. "Escapement" is literally understood, which means "one retraction and one release", and through this retraction and release mechanism, the power can be collected first, and then other parts can be used to adjust the power, so that the movement can maintain smooth operation. The accuracy of the second hand can run in an orderly manner, and the quality of the escapement will affect the accuracy of the mechanical watch! ➤ Product Details Difficulty level: ★★★☆ (the highest five-star) Assembly time: about 2~2.5 hours Recommended age: 6 years and older Included in the package: graphic assembly instructions, painting pigments + watercolor pens Product size: 22cm*9.5cm*28cm (without pendulum) Packing size: 30cm*23cm*3.5cm Material: non-toxic birch Origin: Taiwan https://live.staticflickr.com/65535/51376178085_f04ecc5997_h.jpg **➤ Precautions** Please use the attached sandpaper to polish the wooden parts before assembling, and pay attention to the small parts, please be careful not to swallow them.
