Parents have to warn their children about so many hazards in everyday life. Look both ways before crossing the street. Don't try to pet strange dogs. Don't take candy from strangers - and on and on and on.
Now there's a new one: If you see a 2-liter soft drink bottle outside, stay away from it.
After a methamphetamines laboratory was found in New Martinsville last week, police Capt. Steve Kastigar explained the "shake and bake" method of meth manufacturing to our reporter.
It involves placing potentially unstable ingredients in a 2-liter bottle, shaking it, then leaving it to work. Sometimes, the bottles can explode - which is why some meth makers leave them beside streets and roads to work, coming back later to pick up the product.
"Shake and bake" bottles can be dangerous for that and other reasons. Parents should warn children to stay away from them.
