Silica causes fine vibration when given constant electricity and pressure. Silica is an important material used in electronics, and it is used in semiconductors, solar cells, LEDs, cars, and airplanes. The flowing stream has dark ordinary stones with slippery water moss, but the white brisket, which contains a lot of silica, hides science that does not contain water moss. The reason why water molecules are known to be effective in preventing dementia because of its semiconductor properties. It is because of the silica which is known to be effective in preventing semiconductor properties and dementia that activates the mole molecules by vibrating minutely in a stream flowing with solid white brisket.
