go buy a tank of carbon dioxide.
on the valve attatch a 2L pop bottle lid.
make coolaid, juice, whatever.
attatch the 2L bottle of coolaid to the CO2 bottle. Turn on CO2. shake for 5 minutes or so.
bam, its done!..
for grape/orange/lime/etc use coolaid.
you can get rootbeer flavour syrup and make that (watkins sells it i think, but your rootbeer will be clear)
gotta buy coke or pepsi syrup if you want that.
you can obtain a co2 tank from a pop distributor. i think theres $25 or $50 deposit on the tank, and the CO2 to refill it is pretty cheap.
(my uncle makes his own pop all the time) 😀
oh yeah, carbonated Ice tea with lemon is REALLY good. 🙂
