Most notable is a study of 20,000 Seventh-Day Adventists, who were followed for six years to look for impact of fluid intake on mortality. The researchers found that drinking more water lowered the risk of dying. For women, the risk was lowered by having three or more cups per day, versus fewer than three. For men, three to four cups was much better than fewer than three, and five or more cups was a bit better than that. And at least one study has found that more than six cups of water a day lowers bladder cancer risk relative to less than one cup.
One gallon is about 128 ounces, so if one tea bag is good for 10 oz  of water, then about 10 teabags is good for a gallon. Start with 10  and adjust accordingly with water. 4 people found this useful.
There are four bags to a set. Each set should be identifiable from the other; different colors work well. Bags should be filled with one pound (US) of corn and measure 6 by 6. The final weight of the bag may vary due to the material of the bag itself. Each platform is 2 ft x 4 ft, with a 6-inch hole centered 9 inches from the top.
