Hi Jim,
I saw the recent link in SurvivalBlog to the review of Waterbricks [1]. As a beekeeper I use proprietary 5 gallon 180 degree heat tolerant plastic containers [2] for mixing and feeding sugar syrup to my bees during various times of year when there is no nectar flow.
These containers have a ¾ inch threaded bung in the cap that will accept a plastic valve/faucet which costs $2.75 each (you must ask for them) and there is a smaller cap and provision for a vent to allow fluids to flow easily. At $8.75 each they are about half the price of a Waterbrick. If you buy them in batches of 30, the price is $6.85 each. They are stackable to a limited extent and have a heavy duty carry handle. The opening is 70mm wide so these containers can be used for storing most dry goods as well. I have done business with Kelly for a number of years and they are great folks to work with and provide great customer service & products at great prices.
On another note, beekeeping is not only essential to a healthy environment, the bees make a garden and food crops much more productive, and bees provide a great source of sugar (via honey) in an SHTF [3] scenario, not to mention the many benefits, health and otherwise honey provides. Bee stings are a whole “nuther” story. :O) – Nighthawk
