The Vanishing Private is a 1942 animated cartoon directed by Jack King and produced by Walt Disney. In the cartoon, Donald Duck is ordered to paint a cannon with experimental invisible paint while serving as a private in the United States Army during World War II.

Plot

Donald Duck is doing some camouflage painting on a cannon with yellow, green, and red stripes and black dots. Sergeant Pete sees it and scolds Donald, explaining that it needs to be painted so it can't be seen. Pete then demands that Donald re-paints the cannon to "make that gun hard to see". Obliging to the sergeant's orders, Donald walks to the "Experimental Laboratory: Camouflage Corps", disregarding the "keep out" sign, and walks in. He finds some "invisible paint", which he tests with his finger, and uses it to paint the cannon.
