Petroleum Jelly and Black Light As An Invisible Detection System
This unusual science experiment of how Petroleum jelly reacts under black light can be used as an invisible detection system.
You could smear it in a entrance to a room that you want to check back on later to see if the petroleum jelly has created footprints trail upon the floor . If there are no glowing footprints throughout the room, it was not entered. If you have suspicion that someone has been stealing, looking through or just poking around in your private living quarters – use this method to test if you are correct. Another idea, you could lightly smear an outline around an object on a glass table top, if the item is moved outside the outline upon checking…
This is a low tech option over installing a video camera…. it is not perfect but another bit of knowledge to store in case of need. There is risk of a person slipping, clean up issues and you may not exactly who which person who has invaded your space.
