Visitors to "Behind the Badge" will have the opportunity to try their hand at a variety of skills that are part of a postal inspector’s repertoire. This x-ray image is from one of a collection of hands-on interactives in the exhibition. Although mail bombs are an extremely rare event, postal inspectors are trained to distinguish safe packages from those that are potentially hazardous. In this case, the image reveals a shape, density, wiring, and switch that suspiciously look like a pipe bomb. Visitors get to determine if it is safe or dangerous. What choice would you make?
