And it keeps sparkler sparks out of your hair, too!
An Aluminum Foil Deflector Beanie (AFDB) is a type of headwear that can shield your brain from most electromagnetic psychotronic mind control carriers. AFDBs are inexpensive (even free if you don't mind scrounging for thrown-out aluminium foil) and can be constructed by anyone with at least the dexterity of a chimp (maybe bonobo). This cheap and unobtrusive form of mind control protection offers real security to the masses. Not only do they protect against incoming signals, but they also block most forms of brain scanning and mind reading, keeping the secrets in your head truly secret. AFDBs are safe and operate automatically. All you do is make it and wear it and you're good to go! Plus, AFDBs are stylish and comfortable.
