Things to use for ghost show

Hello folks!

As I've already stated once before I am soon to be starting a ghost show.


Here's the general persona of the whole thing,


It's just two people, and one night vision camera.


No other pieces of equipment, whatsoever. But I'm lookin for surprising methods,


E.G Flour on the floor to detect any footprints or whatnot.


Anybody got any ideas?


Much love
