Henry Kuttner's "The Elixir of Invisibility" (short story, free)

This is a mad adventure using invisibility & visibility potions. Drink from the red labeled vial, & you become invisible; drink from green, to become visible again.

A whole lot of crazy things happen. Reporters disbelieving the inventor receive parcels containing invisible frogs! A thief steals a couple of vials, uses it for a bank robbery. An invisible dog, & sundry other invisible people at public places cause chaos, etc.
