[ Chinese and foreign toy network news] These days caused a lot of controversy because of the US shootings, and the game contains too much violent elements has been pushed to the cusp, but you may not have thought that the game containing violence and the one that once appeared on the market Compared with the toys, it is really awkward. In 1951, in the east wind of World War II victory, American toy company Gilbert designed and built the most horrible children's toy in history, the uranium 238 atomic energy laboratory! Today we all know that the radioactive element uranium 238 can never be easily touched, and those who are not protected from the light will inevitably die. However, this child-oriented toy was successfully listed at the time and was not recalled until 1952. The uranium 238 atomic laboratory consists of a low-level source, a microscope, a radiation calculator, a Wilson cloud chamber for observation of alpha radiation, an electroscope for testing radioactivity plus four samples of uranium ore. I don’t know if the scientific knowledge was not popular enough in the past. Even after seeing the list of kits, parents decided to buy this toy for children for $50. Maybe they want to make children have stronger desire for science, but The results can be imagined. Today, this dangerous toy is being scrambled by collectors for $5,000. Perhaps the ordinary people at that time had no impression of the concept of nuclear radiation, and such a terrible toy would appear. It seems that the key is to improve their knowledge.
