An interesting video has emerged of Youtube Vivafrei using a fidget spinner to illustrate some 'pretty cool scientific principles'.
The footage, captured at a home in Canada, shows the man tilting the spinner on its axis and explaining how the toy remains spinning.
"Fidget spinners are all the craze these days. At first glance, they are totally useless. But they do illustrate some pretty cool scientific principles," the man wrote online.
