Thought:

“In the warehouse of a local weed control agency in rural America, someone discovers several drums of a 15-year-old chemical once used to sterilize soil. The drums are taken to a remote area and left there. A rifle shot rings out. A drum explodes. Had the drums been jarred while at the warehouse, several people would have been killed, for the drums of obsolete chemicals had slowly, imperceptibly, turned into time bombs.”
