ABOUT THAT BOMB IN THE BASEMENT

The University of Military Technology in Warsaw, Poland, has developed a smart-phone app that can detect bombs and land mines, they say. It uses the phone’s magnetometer to detect faint changes in a nearby magnetic field. The app is currently only available for Windows smart-phones.

Our own take on this: It may sound really useful, but we’d like to point out that changes in a magnetic field require the presence of certain metals, especially iron or steel, like the cases for aerial bombs. And as for land mines, they’ve been made from plastic for the last several years and are non-magnetic.
