Diaper sparks bomb alert

Why could I see this happening to me...

BERLIN (Reuters) - An "electronic nappy" used to monitor wetness sparked a bomb alert in a German post office when it arrived in a parcel ticking suspiciously, police in the southwestern city of Heilbronn said Thursday.
"They suspected it was a bomb so they put the package into an empty room and called the police," said a police spokesman. "It was supposed to respond to wetness with bleeping sounds but this one ticked."
Two squad cars rushed to the scene and immediately contacted the sender. Police gave the all clear after they contacted the woman who told them the intercepted package contained only a malfunctioning diaper
