Water Stone will charge up to
1 Gallon of water in 6-8 hours.
The water stones are made from a Carnotite stone, to use this stone you simply let it soak in a gallon of water for at least 8 hours, then drink during the day. The water stone idea is based on a old device from the 1920’s, The Revigator.
Note: The water will only remain irradiated for up to 3 hours when removed from stone.
