Synopsis by Hal Erickson
A chocolate cake mix whipped up by Jimmy Olsen (Jack Larson) turns out to be a special "anti-gravity" formula. Maj. Osborn (Tris Coffin) of the US Army convinces Jimmy that his unusual formula could be of great value to his country. Unfortunately, the crooked Mr. Gannis (Milton Frome) intends to steal the mixture in order to commit crimes. Inasmuch as the plot of the episode involves objects that can float through the air with the greatest of ease, who better to rescue Jimmy and the formula from the villain than that caped flyboy Superman (George Reeves). This was the final episode of The Adventures of Superman's fifth season.
