The small triangular devices have been proclaimed as the ultimate answer for those prone to fidget and they are being snapped up in droves.

The device is basic, hold it, flick it and watch it spin.

The toys have been marketed as a tool to eliminate distractions to help those with ADHD and autism.

You can pick up a spinner in Katherine for a reasonable $5.

It’s normally only a matter of time before a must-have toy is banned in schools and the fidget spinner is no exception. 

A hoard of schools around the world have begun to ban the toys as they are disrupting lessons. 

Katherine South Primary principal Dan Murtas said fidget spinners have only just begun to be popular in Katherine.

“At the moment we haven’t banned them, but ask me again in a week,” Mr Murtas said. 

“We have banned Pokemon cards because there were a lot of fights, we were just putting out too many fires.

“We actually have some fidget packs or sensory tools for the kids who need help concentrating, like squishy balls and stretchy things, and the kid’s attention has gotten a lot better when they have those,” he said. 

A spokeswoman from the NT Education Department said there was “no blanket ban on fidget spinners yet”.

“Speaking to the teachers, they said they haven’t seen too many of them around town yet,” the spokeswoman said. 

“No Katherine schools have a policy against them at the moment.”

Many Darwin primary schools have already banned the spinners.

If it hasn't happened already, expect your kid to be asking for one soon.
