Everyone knows you need to a proton pack to bust ghosts as seen in 1984’s smash hit film Ghostbusters. Well three decades on and science has moved has move on as particle physicist James Maxwell, designer of the latest Ghostbusters proton packs, explains in a new behind-the-scenes featurette at paranormalstudieslab.

The featurette explores the real science that went into the design of the action/adventure/comedy film (I have never been 100% sure how to classify Ghostbusters) which is set for release in July.

During the filming of the latest incarnation of the Ghostbusters franchise Maxwell, a senior post-doctoral associate at MIT, was on hand to give the crew direction on how they could incorporate believable real-life technology into the film.

Dr Maxwell explains the foundation of the science behind the classic proton pack, which used the cyclotron to make particles spin around at a rapid pace, was now an outdated methodology and why the modern day ghostbuster should use a cryogen-cooled synchrotron pack to accelerate particles into a stream of kinetic energy. Ghosts busted!

Either way I think we can all agree it is still not a good idea to cross the streams! I ain’t ‘fraid of no ghosts!

Opening July 15, “Ghostbusters” stars Kate McKinnon, Melissa McCarthy, Kirsten Wiig, Leslie Jones along with Chris Hemsworth, Andy Garcia, Michael K. Williams, Matt Walsh and Neil Casey, with cameos by franchise veterans Dan Aykroyd, Bill Murray, Ernie Hudson and Sigourney Weaver.
