What is wrap foil on door knob when alone?

Wrapping foil around a door knob when alone can help prevent intruders from gaining access to the room or house. The foil makes it difficult for burglars to turn the door knob as it reduces the friction between the knob and the hand. This makes it hard for someone who is not authorized to enter the room or house without a key.

However, it is important to note that wrapping foil around the door knob is not a foolproof security measure, but it can provide some level of deterrence against unwanted entry. Other security measures such as locking the door or installing a security system should also be considered to ensure optimal safety and security.

It is advisable to seek professional advice and install high-quality security equipment to ensure maximum protection against intruders.
