We have a co 2 machine that we hook up to a bottle filled with COLD water and shake until it’s as fizzy as you want it then you’r done “fizzing” as all the boys call it. Next we put soda stream flavoring in it and there you go. There is about 8g of sugar in it and about 35 calories. Now Joseph loves this stuff and he has it about three or four times a week and one day he walks up to me and says “Maria will you fizz?” and looking at his adorable face with his pretty please face on and can’t say no, so I start to fizz and I notice a ssssssssssss sound coming out of the machine and I think it must be leaking to I take the bottle off and taste it and it is not very fizzy. So I tell Joseph the machine is leaking and his water isn’t very fizzy but he tastes it and says “Oooooooooh Maria it tastes very romantic.”
