The new Ghostbuster film got a bit of help from an MIT Physicist to imagine just how the new proton packs would be built, and that equations on the whiteboards were accurate.
Dr. James Maxwell consulted on the film, and advised the production on working through just what would be needed for the proton packs. The video is a brief glimpse of how the packs work. Seeing productions consult real scientists is always really great to see, because it helps improve the little details all that much more.
