The holy hand grenade is made of a material Ken Rohla developed called ormusite, based on the work of Wilhelm Reich, Karl Hans Welz, Nikola Tesla, and many others that creates a subtle energy field called scalar energy. Scalar energy of proper frequencies can reduce stress, promote deeper sleep, promote accelerated healing, and strengthen physiological functions in any living organism: humans, animals, plants, insects, beneficial microbes, mushrooms, and fungi. The ormusite scalar energy disk can improve the taste and properties of water and water-based liquids, and improve the taste and properties of food. The HHG will also structure and reduce the damaging effects of electromagnetic radiation, aka electromagnetic field (EMF) pollution. For sleep issues, see our Rest Shield device for a much more powerful solution.
