Leicester expert contributes to BBC Watchdog report on safety of fidget spinners

Professor Sarah Hainsworth (pictured), Head of the Department of Engineering, has contributed to a BBC Watchdog report investigating the safety of fidget spinners.

The spinners, which were originally designed to help children with conditions such as autism deal with stress, have become a playground craze, spreading globally in recent months.

Safety fears have been raised about the spinners, with some found to fail safety tests. The Watchdog team bought three fidget spinners - marketed as toys for children - from eBay. They had the appearance of a 'death star' or 'shuriken'.

The items were put through testing by blades expert Professor Hainsworth. She tested the spinners by stabbing into a tomato, used as a substitute for an eye, and pork skin, used as a substitute for human skin.

All three spinners had the ability to puncture the tomato, and two out of three were able to puncture the pork skin.
