Forget the tin foil; that’s obsolete. She needs the latest in high-tech thought projection: a colander. It will keep the WiFi’s thoughts out of her head, while still allowing her to project her own thoughts out through the holes.
But she should not get a plastic one; those don’t work. It has to be metal.
Better have that be mu metal.....there could be magnetic effects from the earth here too! :0)
Yes, and the nice thing about a colander is that you can run a rubber band through the handles to fashion a nice chin strap. Now you’re EMF shielded hands-free!
