What is wrap foil around your doorknobs?

Wrapping foil around doorknobs is a common hack used to avoid getting shocked by static electricity. This hack is more commonly used in dry climates as the lack of moisture in the air contributes to the build-up of static electricity. By wrapping foil around the doorknob, it acts as a conductor that dissipates the static charge. It is also recommended to touch a grounded object before touching the doorknob to discharge any static charge. Additionally, foil around doorknobs can also be used as a decorative element during special occasions or holidays.
