Ghostbusters – Holtzmann’s V1 Proton Gun

The charismatic and hilarious Jillian Holtzmann was also a brilliant scientist who armed and mobilized the Ghostbusters with her innovative technical prowess. This hunk of a machine is the prop Proton Gun prototype used on the Seward Street station ghost. They may not have caught the ghost, and Erin almost died, but Holtzmann was stoked that her invention (sort of) worked!
