Many of our users ask about obtaining a suitable large container in which to make the colloidal waters. Although purists would argue that it is better to use glass, we have found that a good quality container made of drinking water quality plastic works perfectly well not only for charging the water but also for long-term storage. We can provide you with a lightweight 7.56 liter (2 gallons) plastic container which also has a tap at the bottom. It has a 3.5-inch opening upon which our generator sits. Because they are so light, we can mail them inexpensively to any country in the World
