Before there was Violet Beauregarde, there was Moe Howard--maybe the first live actor in film to depict turning into a balloon. "Dizzy Pilots" has Moe and the other numbskulls trying to build an airplane. Their inconsiderate antics soon get Moe into a tub of quick-sealing rubber. Of course he thinks inflating his stiffening clothes with Hydrogen gas will solve everything. Before he can be sliced out of the rubber, he takes off through an open skylight and doesn't get far before being shot down. (Hydrogen doesn't react well to hot lead).
