Do you think all schools should not banned fidget spinner toys or fidget cubes in all schools in usa becuase they still will not play attention to class or will still bring them will them to school or to their class?

Well the fidget spinner stuff is actually meant for people with ADHD. But a few people have been known to focus a little better then they normally do when they have the toy in their hand. Now if it disrupts class time or if they are only focusing on the toy and their grades start to drop then yes it should be banned. But only for the students who are to focused on the toy.
