EMF Blocking Crystals-Rocks and Foil?
I tested the EM radiation blocking ability of these crystals/rocks: shungite, black tourmaline, selenite, hematite, pink Himalayan salt rock, and also Aluminum Foil.
I was skeptical about the blocking ability of the crystals/rocks and their practical use, if they were able to block radiation.
Since I understood you could use metals to build a Faraday cage that would be able to block EM radiation, I thought using aluminum foil would be more effective.
