so im thirsty. i go to the fridge, looking for OJ. all we have is some Berri 'Creations: morning up'n'go juice" read the ingredients and its OJ, pineapple, mango, passionfruit, all that. the thing is, the plastic container is swollen and pressurised. so i open it and it fizzes and froths up. now, i remeber seeing this container outside for a couple of days, in the sun i think. my brother brought it back from camping or i dont know where. i pour myself a glass once it has calmed down, have a sip, and its farking carbonated well it bloody seems like it. not listed on the container as carbonated, but i think it's fermented that much that it has a fair CO2 store in it now yummy :?
