This is the world’s tiniest fidget spinner – and it’s smaller than the width of a human hair
The researchers “printed” the device.
Scientists have made the world’s smallest fidget spinner – because it appears we just can’t get enough of this toy.
The tiny gizmo measures only 100 microns wide, is smaller than the width of a human hair and is barely visible to the naked eye.
The spinning device was created by a team at the Oak Ridge National Laboratory’s (ORNL) Centre for Nanophase Materials Sciences, which develops cutting-edge nanomaterials used by other scientists in its experiments.
The process involves using a focused laser beam to draw a shape resembling a fidget spinner.
The excess liquid is then removed and the tiny device is rinsed and developed by the scientists under powerful electron microscopes.
“It’s a compelling way for us to reach out to the next generation of scientists.”
To see how the device worked, the scientists put it under a powerful optical microscope and blew air on it.
The team will now create an interactive version of the microscopic fidget spinner for the ORNL Travelling Science Fair.
