Anti-wi-fi paint.......WTF

Researchers say they have created a special kind of paint which can block out wireless signals.

It means security-conscious wireless users could block their neighbours from being able to access their home network - without having to set up encryption.

The paint contains an aluminium-iron oxide which resonates at the same frequency as wi-fi - or other radio waves - meaning the airborne data is absorbed and blocked.

By coating an entire room, signals can't get in and, crucially, can't get out.
