If you love fidget spinners, prepare to be amazed with the latest creation of the world's smallest fidget spinner!馃槸 MinebeaMitsumi Inc. from Minato from Tokyo, Japan built a spinner that measures just 5.09 mm (0.20 in) long, easily fitting on the tip of one's finger.
It was built using MinebeaMitsumi Inc's existing record-breaking product, the smallest commercially available steel ball bearing which itself is a mere 1.499 mm.
The entire fidget spinner weighs a feather-lite 0.027 g (0.00095 oz) - and actually works.
