The Trick Using Aluminum Foil on Door Handles
The Investigation
The next day, curiosity got the better of me.
I searched online and found dozens of strange theories. Some people claimed foil could prevent static electricity. Others said it was a homemade security trick.
One explanation appeared again and again.
According to several posts, if someone tries to quietly turn a door handle while you’re inside, the foil will crinkle loudly and alert you. It may also make it harder to get a firm grip on the handle.
The idea sounded simple, but I wasn’t completely convinced.
Still, it made more sense than any of the other explanations I found.
Maybe my neighbors were simply being extra cautious while away.
Or maybe there was another reason entirely.
