Yes, Wiz, in the generic sense it does.
However, in the real reality, real tin foil is hard to come bye.
Consequently, I use Aluminum foil as it is readily available.
But that's good, because of it's greater inherent electrical conductivity
combined with occular reflectivity,
it is plenty many much better than real tin foil.
I wear my
under my cowboy hat all the time.
I'm able to work with out the distraction of those who are trying to control my mind.
These really work.
One caution however: when I take my monthly shower,
I have to ground myself and the deflector beanie to the toilet.
For a double check, ask Hoxlund and Monte.
They wear them all the time and I heard about it from them.
