What is the salt trick?

The "salt trick" often refers to a method, sometimes considered a home remedy, to allegedly test for paranormal activity or the presence of spirits. It typically involves sprinkling salt, often in a line or circle, in a specific area where paranormal activity is suspected.

The idea behind the salt trick is that salt is believed by some to have purifying or protective properties, thus acting as a barrier that spirits cannot or will not cross. If the salt is disturbed overnight, it is interpreted as potential evidence of paranormal intervention.

It's important to note that there's no scientific basis to support the effectiveness of the salt trick. Any disturbances in the salt could easily be caused by natural phenomena such as drafts, insects, animals, or even settling of the building. Therefore, it's generally viewed with skepticism by scientists and paranormal investigators who rely on more empirical methods.
