Here is a warning from local law enforcement agencies about plastic bottles that can become a potential lethal bomb.  You are being warned about people leaving plastic bottles on lawns, in mail boxes, in gardens and on driveways and then waiting for someone to pick them up at which point they can explode with deadly results.  Some of these plastic bottles are being filled with lethal ingredients that, when mixed together and then shaken, explode with an intensity that can be lethal, or at least can severely injure someone.  And when they do explode, the contents are scalding hot.    Police advise that if you see something like this, do NOT PICK IT UP.  Call the police immediately.  Police say there have been no incidents of this happening in the Magic Valley area but there have been come in the Boise area.
