Tinfoil Hat

Tinfoil Hat is a headwear item, typically constructed from one or more sheets of aluminum foil, or a similar metallic material. It is often worn in the belief that it can protect the brain from threats such as electromagnetic fields, mind control, or mind reading.

The tinfoil hat is primarily used by individuals who believe they are subject to such external influences and seek to shield themselves. It is also widely recognized as a cultural symbol, often used in media and popular culture to represent paranoia, conspiracy theories, or eccentric behavior.
