I've seen these machines in the stores that advertise the ability to make your own soda pop flavors and carbonated drinks. But some of the machines run as much as $99 for the whole set up. This got me thinking. Isn't there an obvious and cheaper way to do this. This is what I came up with. Its my First inscrutable so let me know if it was helpful!

Step 1: Buy Carbonated Water...

I said it was obvious.... buy a 2 liter of plain carbonated water, or soda...

Step 2: Buy Concentrate...

The concentrates for these machines are not that expensive, and when you consider that you can mix and match em or make your soda as sweet as you want, its not a bad deal. 1 bottle of concentrate will make 12 liters of soda.
