William Bleckwenn's Stethoscope

Origin
William Bleckwenn was an American neurologist, psychiatrist, and military physician. He is credited with developing the process of using sodium amytal to treat catatonic mute patients. The process was later dubbed as "truth serum".

Effects
When placed on a target's chest, the stethoscope will force the target to think of nothing but the answers to the user's question. The truth will run inside the target's head over and over until it is blurted out.

Due to free will and varying levels of stubbornness, there is no approximate timeline for the effectiveness of the artifact. For some targets it could take seconds, while others may hold out for hours.

Collection
Was going to be used along with the Spindle from the First Torture Rack to extract the truth from Artie in the Alternate Warehouse 13 Paracelsus created. Collected by Jack and Rebecca shortly after Bleckwenn retired for health reasons.
