Ghostbusters: 7 Scientific Facts To Make You Hate It Less

5. Ghost Trap

The Ghost Trap is used to, er, trap ghosts and its alternative name, the Muon Trap gives us a clue as to how it works.

A muon is a subatomic particle similar to an electron, but smaller and heavier. Given that we've already learnt that ghosts are made up of those negatively charge electrons, with a little bit of sciencey hocus pocus, muons could be used to contain the spooks.

If you could find a way, and of anyone can it's Holtzmann, of converting the electrons in the ghost's form into muons, it would shrink the atomic radius down by 200 times without changing any of their properties and conserving mass.

In short: It's a compression field.

This supernatural trash compactor allows the ghostbusters to wrestler a 30 foot spook into a container the size of a lunchbox by cutting its electrons down to size.
