Samuel Clemens' Riverboat Whistle

Origin
Samuel Clemens' Riverboat Whistle - Samuel Clemens, who would later be known best under his penname Mark Twain, is a famous American writer who became particularly famous for his presentation of the darker sides of humanity. He would go on to capture the imaginations of an insurmountable amount of readers, but before all that he was a riverboat pilot along the Mississippi. Now, while most people know about that story, not many know that Clemens was a very good friend of one particular Nikola Tesla.

The story goes that when Nikola Tesla was told he could only tell one person about a secret government project he had been hired on, he had been unwittingly told he should probably tell his wife. Never married, Tesla cheekily called Clemens. Whether that story is true or not is debated, but Clemens was made aware of the Warehouse, and when it was discovered that Clemens' old whistle from his riverboat days had become an artifact in 1930, Tesla was given the artifact (and a vat of neutralizer) to remember his deceased friend.

“The Fox and the Hound” by Disney Studios was partly inspired and based off this artifact.

Effects
The whistle, when blown, adjusts the wavelength balance of the brain so that conflicts are resolved peacefully, promoting equality and decency between estranged parties. However, the whistle does have a nasty habit of making Halley's Comet's orbit go a little funky...which is why no one talks about the accident with the Mars Rover...
