Duncansville police say a resident found the device Sunday and became suspicious was when he read a story about methamphetamine labs in the Altoona Mirror newspaper.
Police say the item is an anhydrous ammonia reactor fashioned out of a gasoline can. It was found on game lands just west of Duncansville, about 80 miles east of Pittsburgh.
Duncansville police Chief James Ott tells the newspaper that the device hasn't been linked to any known clandestine lab and police don't know who made it.
The can was frozen which kept the chemicals from reacting, but the chief says they would have been dangerous had they thawed or been exposed to water.
