This is not your grandfather's tin foil hat...

Tin foil hats just got way more interesting. Italian designers made a hat, a collar and a visor that look fancy but also serve a classic tinfoil hat purpose. The accessories actually work to ward off neuroimaging surveillance.

If a brain scan is detected, the device will distract the wearer for a second to scramble their brain activity and protect their privacy. How? In one case, by hitting the wearer with an electric shock.

Small price to pay for protecting your privacy for a millisecond?
