Day 34.1
Lego, consists of colorful interlocking plastic bricks and an accompanying array of gears, mini figures and various other parts. Lego bricks can be assembled and connected in many ways, to construct such objects as vehicles, buildings, and even working robots. Anything constructed can then be taken apart again, and the pieces used to make other objects. The toys were originally designed in the 1940s in Europe and have achieved an international appeal, with an extensive subculture that supports Lego movies, games, video games, competitions, and four Lego themed amusement parks.
Lego pieces of all varieties are part of a universal system. Despite variation in the design and purpose of individual pieces over the years, each remains compatible in some way with existing pieces. Lego bricks from 1958 still interlock with those made in the current time, and Lego sets for young children are compatible with those made for teenagers. Bricks, beams, axles, gears, mini figures, and all other parts in the Lego system are manufactured to an exacting degree of precision. When snapped together, pieces must have just the right amount of strength and flexibility mixed together to stick together. They must stay together until pulled apart. They cannot be too easily pulled apart, or the resulting constructions would be unstable; they also cannot be too difficult to pull apart, since the disassembly of one creation in order to build another is part of the Lego appeal.
Testing and quality control are paramount concerns in the construction and manufacturing of Lego products. Bricks, beams, axles, mini figures that to not meet testing standards are recycled, melted again, and formed into new legos.
