Actually it wouldn't work that way, if you want to carbonate any liquid you have to make it in an air tight environment, co2 passing trough a liquid will do nothing at all, it has to dissolve in to the liquid, no way it will do that if it has an alternative escape route, also it will take some time, i could estimate a couple of hours for the process, maybe even longer.

When i was a kid i used to blow out corks from bottles with vinegar and baking soda, and i can tell you that if you put the cork on too hard the bottle will…go boom, so you might want to do this in pressure kegs.

i give you 2 good alternatives, put coolaid in sparkling water (bought)
or in some stores you can find digestive, or mineral additives that will put the bubbles in for you (it's the equivalent of alkaselzer without the medication)

*Also… if you get stung by a bee… make a little water and baking soda paste and put it on your sting. it will ease the pain and suck out venom.

Does this mean you are adding laundry detergent and vinegar to your orange juice? It sounds like it will really mess it up!

actually, if you make this, improve on it by letting the tube hang at the bottom of your beverage, exposing the CO2 to as much fluid as possible. just don't forget to add a vent at the top!
