Handphones Silenced by Kenneth Lyen The fight against terrorists may have one benefit for theatre goers. A wallpaper has been developed  containing a metal grid which blocks out radio signals. This prevents terrorists from detonating a bomb by remote control. The wallpaper can be put up in selected areas of airports, for example, so that any suspicious packages can be brought to this area and any bombs inside cannot be triggered off by a phone call. If you install the wallpaper in cinemas and theatres, no handphones can receive any signals. Hence no more nuisance phonecalls or SMS’s. Yippeeee!!! If you were a doctor on call, you may be uncontactable for any emergencies. The antiterrorist use of this wallpaper may actually be less significant because many terrorist groups do not rely on remote controlled bombs, but rather on suicide bombers who detonate their bombs manually. It is a tragedy of our times that unresolved political problems impel people to commit such barbaric acts. Maybe we can luxuriate for a brief moment with a false sense of security, watching a film cocooned in a cinema with radiowave silencing wallpaper! Next, can they invent noiseless crisps and popcorn?
