Spinner
The hand spinner, also called fidget spinner, is an object that was created in 1997 by an American lady who had an autistic daughter; This object served to de-stress and calm her. Then this object became global. It became very fashionable in the recreational schools of French schools in the spring of 2017.
The hand spinner can cost from € 0.90 to € 150,000, some are encrusted with diamonds, etc. There are many different shapes and colors. The hand spinner works thanks to the ball bearing.
It is possible to make many figures while it is being rotated: put it on its nose, its forehead, its knee, to make a "tour of the world" (to make a turn with its arm with the hand spinner posed on a finger) 
I had one of those and I love playing with that. It can truly relieve stress. 150,000 is crazy you know!
