Aluminum Blüthner Piano from the ''Hindenburg''

This piano, made by Blüthner for the LZ 129 Hindenburg, was carried aboard the airship, but taken out before the Hindenburg disaster. Playing the piano causes a fire to emerge. The higher the note, the hotter the fire.

Origin
Blüthner, formally Julius Blüthner Pianofortefabrik GmbH, is a piano-manufacturing company founded by Julius Blüthner in 1853 in Leipzig Germany.

LZ 129 Hindenburg (Luftschiff Zeppelin #129; Registration: D-LZ 129) was a large German commercial passenger-carrying rigid airship, the lead ship of the Hindenburg class, the longest class of flying machine and the largest airship by envelope volume. It was designed and built by the Zeppelin Company (Luftschiffbau Zeppelin GmbH) on the shores of Lake Constance in Friedrichshafen and was operated by the German Zeppelin Airline Company (Deutsche Zeppelin-Reederei). The airship flew from March 1936 until destroyed by fire 14 months later on May 6, 1937, at the end of the first North American transatlantic journey of its second season of service. Thirty-six people died in the accident, which occurred while landing at Lakehurst Naval Air Station in Manchester Township, New Jersey, United States.
