History
In the beginning, his invention was credited to the North American chemical engineer Catherine Hettinger who in 1993 applied for a patent for a spinning toy , who in 1993 applied for a patent for a “spinning toy”, which he lost in 2004 for not paying $ 400 asked for renewal rights. The origin of the restless spinner comes from when she suffered from myasthenia gravis , an autoimmune diseasethat he did not allow her to play with her daughter. A couple of decades later, however, the invention became very popular and millions of units are sold worldwide. Their great popularity among schoolchildren has led to them being banned in some schools as they are considered to be distracting to students. In some countries it is used as a tool to help patients with autism , stress , anxiety or depression.; although it is also considered dangerous for young children due to choking hazard. This original toy has as an idea of game the rotation between the fingers of the device by means of small bearings that rub in a very light way. Thus a small force exerted on its small blades is capable of rotating this small mechanical spinning top very quickly and for a remarkable period of time. All this without applying more thrust than the exercise with the fingers of the hands. This addictive toy usually has three or four blades and in the center of the spinners, a bearing on which the main turn occurs and at the ends of the blades, other bearings that when applying the initial turning force rotate in the direction contrary to the main one.
