Why recreation courses swear by the "hand spinner"

 "Hand spinners" is the new fashion for recreational classes. That came very quickly: what makes a toy or a game meet success or not?
The first person to have spoken to me is my best friend at the end of April, with a lot of advance, evoking the presence of a kind of top (Charlotte, your description was rotten) in her son's classroom, . Then, articles were published. That same day, my son came back from school and told me he wanted one.
The playground modes seem to have always existed, even my son who is in his second year of elementary school analyzed it: "there were Pokémon, footage, still the Pokémon and today The hand spinner ". I also remember Panini images, skipping ropes, balls, and so on. We all have stuff to tell, confirmed by the real specialists of the subject like Pascal Pinteau author of a book on Toys cult in 2008:

"Schoolyard toys have existed since the beginning of the 20th century with bones and marbles. Beginning in the 1970s, we see the appearance of trademarks with related cartoons or movies, Star wars with its small figurines being the most emblematic example. "

But success can be ephemeral, or not arrive at all:

"The financial stakes are enormous. Matel and Hasbro do a lot of testing to find out what kids can like. Brand experts watch kids play behind untouched mirrors. They choose children of all ages, both sexes and different backgrounds to analyze what could work anywhere and spread to all schoolyards. "

It remains a part of unpredictable, it is not known why a trick takes or not and hard or not ... some successes are a priori mysterious, Pascal Pinteau, also director, with Michel Viotte, a documentary on toys, Explained by the "talent of the toy": "Behind a toy that works there is often an original idea, sometimes an innovation (as for the Spinner) both technical and playful. It is this new aspect that will delight kids and create desire in a significant part of children. "
