is another experiment that other investigation groups have
used in the past which has given interesting results. The
idea is to spinkle talcum powder down over a floor where footsteps
have been heard or things have moved to see if any imprints
will be made. Also, such powder can be sprinkled onto trigger
objects to see if anything appears if said trigger object
moves during the investigation. To be able to clearly see
the talc on the floor (and to ensure that absolutely no mess
is made) the talc is spread evenly over a black sheet of lino
or bin liner. Slightly crude but by no means less effective.
The best place to set the floor experiment up is undoubtedly
where people have reported seeing figures or hearing footsteps.
