No this is not a commercial for some diet beer or soda, rather a different way to shed pounds....from your backpack.  I came across this -

while reading Gizmodo.  Looks like Pat's Backcountry Beverages is going to release a powdered soda mix and highly concentrate beer mix.  Why lug around the weight of all that water in your soda and beer while hiking and camping?  You get a specially designed bottle that features a pump on the lid for pressurizing its contents, and then to make soda you just mix the soda powder, carbonizing agent and some water and boom - instant soda!

The beer is actually a highly concentrated liquid.  Add some water and instant beer.  You can read all about it on the Pat's Backcountry Beverages site.

So, what do you think?  Good idea?  Would you shed the pounds and try this out?  The key to me is the taste - if it taste like the real thing, sounds like a very cool idea!
