A viral hack suggests wrapping aluminum foil around door handles to detect possible tampering. The foil may crinkle, tear, or show marks if someone touches or turns the handle, giving homeowners a simple, low-cost way to notice unusual activity.
However, experts warn it is not real protection and won’t stop a break-in. It should only be a small awareness tool, while actual home security relies on strong locks, secure doors, lighting, cameras, and other proven safety measures.
