What is wrap doorknob in foil when alone?

Wrapping a doorknob in foil when alone is a simple trick that can help prevent unwanted access into a room or space. It works by disrupting the electrical circuit that is necessary for opening the door. Essentially, the foil acts as a barrier that prevents the electrical current from flowing through the doorknob, making it impossible to turn.

To wrap a doorknob in foil, you will need a sheet of aluminum foil that is large enough to cover the entire knob. Simply wrap the foil tightly around the doorknob, smoothing out any creases or folds as you go. Be sure to cover every inch of the knob, including the back and sides, so that the foil creates a complete barrier.

While wrapping a doorknob in foil is a temporary solution that is not foolproof, it can provide an extra layer of security when you are home alone. It is important to remember that this technique should not replace other home security measures, such as locking doors and windows and installing an alarm system.
