Ghost in a Can was a Coca-Cola promotion of Ghostbusters and later Ghostbusters II. It was a design that featured the Ghostbusters Logo for the given movie and Slimer. There was also a caption on the can saying that there was a ghost imprisoned inside the can and that if you opened it to drink the soda, the ghost would escape. Most of these were tie-ins to food promotions or were specially labeled cans of Coke-Cola. Also many were sold in foreign markets, giving them all a translated charm to them.
