Fidget spinner

Hi today I want to tell you about fidget spinner.
Nowadays we have a lot of gadgets but some of them I can't uderstand.
Fidget spinner is a new toy, reportedly it is a stress-relieving toy. This toy can help you focus and de-stress.
Fidget spinner was invented in 90s but it became popular in this year.
On first sight this seems be useless, but if you think about it this can be usefull.
I have problem with stress when I'm talking and often I have something in my hands, a pen or something like that and it really help me focus, but I think that this gadget is to big and I wouldn't go with it to exam.
However this toy is very popular and people make tricks with it.
You can see a few below.



When I read about it I found something else and I think that this is better.
Fidget cube is smaller and this is a cube with „an on/off-style switch, gears, a rolling ball, a small joystick, a spinning disc, a rubbing pad, and depressible buttons”.
I think that I will buy something like this for my exams :D
