How? Well, just look at the foil the next day. Any wrinkles or folds mean someone messed with your door. It’s like a silent message saying, “Hey, someone tried to get in.” This visual cue is a discreet but effective way to spot unauthorized access.
But that’s not all. If you’re inside your home, the foil makes a crinkling sound if someone tries to open the door. It’s like an alarm that immediately tells you, “Hey, something’s not right.” This noise can help you act quickly, whether by calling for help or making sure you’re safe.
