The Plastics Inventor is a Disney animated short from 1944, produced in Technicolor by RKO Radio Pictures, featuring Donald Duck.
The cartoon begins with Donald listening to the radio, and has a massive pile of junk, just enough to invent his plastic airplane.
Unfortunately, a rainstorm starts pouring and the plastic airplane begins to melt, with Donald attempting to repair it with extreme difficulty.
The airplane eventually melts away completely, forming into a parachute as Donald lands safely on a tulip patch.
The short was released on December 6, 2005, on Walt Disney Treasures: The Chronological Donald, Volume Two: 1942-1946.
