This is the one thing in my life which I could never give up... Even though I broke my back and hurt my hands carrying the bottles up the stairs, even though I felt guilty about the absurdity of using all the energy and materials necessary to produce the innumerable bottles I'd consume and the gas necessary to ship them, even though the modest cost of a bottle was adding up to several hundreds of dollars a year, I could still not give up the habit.
I'd thought of building some sort of seltzer making set-up, and found a few descriptions of how to do it, but they all seemed too involved, (and dangerous) to be practical for me. Then I found the soda club
, and it did, literally, change my life. In a way it is DIY because I now make the selzer... I don't need to carry the weight or pay for the water. I use tap water (transported via the force of gravity) and just pay for the bubbles -- about 20 cts per liter. Not only do I save a whole lot, but I don't have to carry the water and I never run out! Safe, easy, cheap. What more can you ask for?
